Friction-wedge locking device /6, 7/ contains two two shoulders of the locking lever 1 is located on pins in the side niches of the 2 receiver on both sides of the shutter. The rear shoulder of the locking lever 1 is made in the form of a narrow ridge with 3 sloping cut back edges of interacting with a lateral projection 4 rolling stop-plunger 5, which simultaneously re is it the recoil spring stop 6, and the front of his shoulder, his face party interacts with the breech with a sloped stepped ledge 7 of the shutter. For the passage of the ridge 3 during Shuttle movement of the shutter speed ledge 7 provided with a longitudinal groove 8.

Unlocking the device with a compensation mechanism to delay the moment of shutter release contains gas engine 9 on the piston rod which holds the plunger compensation spring 10 with a side bracket for flexible mounting of a spring-loaded ratcheting hook-pusher 11. The transverse vertical plane of the rotational movement of the ratchet hook-pusher 11 in its longitudinal movements occur under the action of the spring 12 and the inclined stationary ledge 13, acting in turn on his side of the ledge 14. Rolling stop-plunger 5 through the bolt rod 15, on the upper side of which is grooved emphasis for the kinematic connection with the ratchet hook-pusher 11. The mechanical part of the bolt rod 15 from the gate communicates with a lateral projection 16 of the rod extension 17. The lateral projection 16 is moved through the longitudinal groove of the wall of the shutter, which limits the magnitude of its displacement. If manual removal of the bolt in its rear position after removal of the side protrusions 4 a stop-plunger 5 from the od of the ridges 3 of the locking lever 1 bolt under the action of the bolt rod 15 through a lateral projection 16 on the rear wall of the longitudinal groove moves backward. The front part of the bolt rod 15 interacts with a movable carriage 19 of the reloading handle 20.

Return spring 6 is located inside the shutter /6, 7/. Shutter it interacts through the movable stop-plunger 5.

Udarnikov firing device with two firing modes /7/ is located inside the gate and inside the return spring 6 and is equipped with a drummer 71 from the rear spear tip 72 with placeables annular ledge hammer spring 73, two coaxially arranged sleeves - internal reference 74 and the outer movable 75. On the free end portion of the supporting sleeve mounted on the rear side of the receiver, made of spring clamps 76 leading whispered and 77 whispered timer, and a movable sleeve - terminal fork tabs 78 with slipped on easily on spring leading whispered 76 and change their current length and, consequently, power. The amplitude of longitudinal movement of the movable sleeve 75 is limited by the length of the longitudinal groove 79, made in the wall of the support sleeve 74, which includes a male protrusion 80, mounted on the inner side of the movable sleeve 75.

The mechanism of longitudinal movement of the movable sleeve includes a carriage 81 located inside the supporting sleeve 74, is placed inside on the axis of the spring-loaded plungers 82, carried out is in the form of two shoulders of the levers, rear shoulders which pass through longitudinal openings in the wall of the supporting sleeve and engages with the slot stops the movable sleeve, and the front shoulders equipped with a mechanical bevels with the possibility of occurrence between them spear tip 72 drummer 71, rotate them due to this axis and excretion rear shoulder out of engagement with the slot stops the movable sleeve 75. The carriage 81 is connected with the trigger pull 37 through two shoulders lever 83 and a short rod 84. When the output from engagement with the plungers 82 and a movable sleeve 75 under the action of the spring 85 will move forward and fork lugs 78 will move to the spring leading whispered 76 and reduce their effective length, thereby increasing their strength.

Combat spring 73 is located on the drummer 71 in the middle part of the inside of the guide sleeve 86 immediately adjacent to the head part of the bolt. With their outer side of the sleeve 86 is also provided with a mechanism for rolling a stop-pusher 5 return spring 6. Guide sleeve 86 at the rear of its parts has a hole through which passes the pin, and an internal annular ledge, which is the rear stop mainspring 73. On the opposite hand combat spring rests against the front annular projection 87 drummer. On the middle part of the inner surface of the guide sleeve 86 has kolicevo the ledge 88, valid when moving the shutter from the rear end position on the annular ledge 87 drummer and liberating his spear tip 72 of the spring grips whispered timer 77.

Firing mechanism operates as follows. When the waste gate in the rear end position when released the trigger spear tip 72 drummer 71 sequentially drops for hooks leading whispered 76, whispered timer 77, is included between the front end bevels two shoulders of the lever pushers 82 and rotates them, bringing them back shoulders out of engagement with the slot stops the movable sleeve 75. Fork lugs 78 slipped over the spring leading whispered, their current minimum length, and maximum power. When reverse motion of the shutter lever pushers again engages with the lugs of the movable sleeve 75, the spring hooks whispered timer 77 capture the spear tip 72 and hold it, resulting combat spring 73 is compressed. Near the front end position of the bolt under the action of the annular ledge 88 on the annular ledge 87 spear tip 72 disengages from hooks whispered timer and is caught by the hooks of the leading whispered 76. At this moment the shutter reaches the front end position, so that the impact annular ledge 8 on the annular ledge 87 drummer stops, the strength of the spring is insufficient to overcome the resistance of hooks leading whispered 76 with reduced current length and the drummer remains cocked.

When the trigger is pulled, the trigger rod 37 will rotate the trigger lever 83 and through an associated short rod 84 will take the carriage 81 ago, and along with it through two shoulders levers-pushers 82 and the sliding sleeve 75. Fork lugs 78 are moved from springs leading whispered 76, the effective length will increase, and the strength of the resistance will decrease and now spear tip 72 under the action of the hammer spring 71 is released from the hooks leading whispered 76, will break the capsule and will be shot.

Further work the trigger depends on full or partial rotation of the trigger, which corresponds to a full or partial movement of the carriage 81 ago. In case of incomplete move the carriage back interaction spear tip 72 with two shoulders levers-the pushers 82 is maintained and working mechanisms corresponds to the described technology. This technology determines the mode single shooting. Incomplete rotation of the trigger after executing the shot, you must release the trigger and press it. Under the action of the spring the trigger through the trigger pull 37 and 84, the carriage 81 moves the EAP is red and the rear shoulders of the lever pushers 82 will drop for interlocking lugs of the movable sleeve 75. The trigger mechanism is ready for the next shot.

At full turn trigger the carriage 81 is discharged in the rear end position and the spear tip 72 is not already comes to the front of the lever arms-pushers 82, rear shoulders remain in the slot stops the movable sleeve 75 and hold it in the rear position. Therefore, the spring hooks leading whispered not intercept the spear tip 72 and the drummer after his release from the hooks whispered timer 77 breaks the capsule and produces a shot. When fully pulling the trigger the cycle repeats and implemented by the continuous shooting. After the trigger is released, the striker remains in the position of the combat platoon. The calculation of the power characteristics of the interacting springs is made on the basis of the stated technologies.

The control mechanism firing modes through the trigger contains suspended on the cross trigger 31, executed on his sleeve bracket 47 and located ahead of him right and left of the bounding stops 48. When the longitudinal rotation of the trigger to bias one of the limit stops 48 is engaged with the bracket 47 and blocks full stroke the trigger. The bracket 47 is pivotally connected with the trigger pull of 37, which is at the same time centering the trigger Crouch is to spring. Incomplete course trigger match mode single shooting, full speed mode continuous shooting.

The mechanism of the shutter in the rear position is extremely simple and is entirely consumed in the last section of the longitudinal-line store. Mechanism /6/ is a magazine follower cartridges with high rear restrictive protrusion 89. After feeding the last round and a shot at the departure gate at the rear end position limiting protrusion 89 of the applicant cartridges takes place the last cartridge and locks the bolt in its rear position. After removing the magazine, the slide is moved to the forward position.

Rod reflector liner contains longitudinal spring-loaded rod, located inside the shutter so that its front end portion communicates with the opposite zacapu selector edge of the bottom of the cartridge, and the tongue 57 is moved longitudinally through the slot of the bolt and cooperates with the rear wall of the longitudinal groove of the balancer, as with the reflective focus.

Automatic fuse /6/ containing two two shoulders of the lever 59 and 60 connected by a thrust 61. The lever 60 is spring-loaded. The free arm of the lever 59 engages in the normal position with the ledge 62 of the sleeve trigger kr is CCA and block rotation. The free lever arm 60 extends beyond the front edge of the arm of the machine and is the push arm guard locking end positions. If it is pressed when performing combat grip the arms of the lever 59 rotates and releases the trigger from the lock.

The hinged shoulder 67 serves to stabilize the machine in different positions combat addressed. The machine uses a longitudinal multi store for 45-60 cartridges located in the rear of the weapon. The center of gravity also moves backward, without shoulder pads can lead to difficult-controlled changes of position when shooting and reduce its effectiveness. Fixing the tilted position of the shoulder is driven ratchet latch 68. Return tilted shoulder armour to its original position under the action of the spring /not shown/ when extracted from engagement with the ratchet tooth of the latch.

In many combat situations handguard is more preferable in comparison with extra grip. It is in some cases provide greater resilience weapons and maneuverability. When shooting over long distances in machine-gun mode requires, in addition, the rigid support in the form of a bipod. Field machine has an arm-forearm 69 with retractable bipod shown in Fig. The handle contains corpus, inside of which there are retractable telescopic parts 91, provided with inner and outer threaded belts 92 for screwing links in extended position. The last internal link on the outer end portion has a supporting annular space 93, and inside link is retractable abutment bayonet 94 spring 95. Extreme positions of the arm-forearm fixed latches /not shown/.

Jet-acoustic compensator /Fig.9/ includes axially spaced jet nozzles 96 and nozzle chamber 97, which are interconnected gas-dynamic nozzle 98 with high input impedance, such as nozzles Board, done in conjunction with diffusers 99, forming a Central gas channel. First from the muzzle Tresa jet camera also has an output channel 100 on the rear jet nozzle 101. In the output part of nozzle holes are arranged to frequency-convert grid 102 with elongated cells. Last /target/ jet chamber 103, in addition to the nozzle and gas Central channel also has the gas exits into the environment directly through the TV-cell frequency-converts the grating 104, made in the form of diffusers. The external surface of the device contains the longitudinal and transverse smoothing grooves /flute/forming the exposed area with nozzle orifices. In arena front smoothing grooves are made deeper. To further reduce the acoustic component reactive-acoustic compensator equipped with ejector casing, made in the form of a cylindrical grid cells which represent the ejector nozzles for each jet nozzle. Ejector shroud slightly increases the size of the reactive acoustic compensator, so it can be made removable. With the barrel of jet-acoustic compensator associated screw belt 105.

When fired, the powder gases, as anticipating the bullet and following it through the Central gas channel, sequentially go through all nozzle chamber 97, continuously reducing the pressure due to the expansion in the nozzle chambers, and outlet gas streams through cell-channels of a frequency transform of the grating 102 jet nozzles 96. The energy loss of the gas stream occurs also when to allow transition from one camera to another in the nozzle-diffuser 98-99. Sound energy shot, focused only on certain frequencies while passing the gas stream through the frequency transform of the lattice, is scattered in a wide area of the audio spectrum and shifts in the field of high frequencies with a high level of attenuation. In addition, along and transverse smoothing grooves together with the ejector nozzles create conditions for a more deeply what about the suction air of the gas jets and reduces turbulence, consequently, the level of the acoustic component. The latter allow cameras powder gases reached with great loss of energy and through diffusers front face into the air almost in a laminar mode, not arousing strong vibrations, the more that smoothing the slots in the front part is made deeper.

Locking with the locking mechanism and unlocking with compensatory mechanism to delay the moment when the bolt unlocking device /figure 10, 11/ include packing hooks 114, in the form of flat rods with lateral protrusions 115 on the end parts, a locking cutout 116 on the underside of the rear end portion and the protrusion of the plunger 117 is made directly behind the front side of the locking cutout 116. Lateral protrusions 115 of the bolt hook 114 moves: front - longitudinal, rear - inclined grooves 118 of the receiver. Under the front longitudinal grooves 118 to establish the s spring retainers 119 end position gate hooks. The shutter is equipped with side locking tabs 120, paired in a locked position with the locking notches of the bolt hooks, i.e. in the extreme forward position of the shutter /figure 10/ packing hooks are also in the front position, and the locking tabs 120 are in the locking notches 116. When you move the slide back to its locking tabs 120 are on the rear wall of the locking notches 116 and gate hooks 114 are moved together with the slide under the influence of inclined grooves 118 of the receiver on the side protrusions 115 of the locking notches disengage from the locking lugs and the bolt hooks are fixed in this position by a spring retainers 119 /11/. When you move the bolt forward before reaching the front end position to its locking tabs 120 are on the ledges-pushers 117 gate hooks and they move forward together with the bolt, under the influence of inclined grooves 118 of the receiver on the side protrusions 115 of the locking notches 116 engages with the locking tabs 120 and the shutter smothered.

Lock samouprave gate hooks are made at the initial moment of the shot and runs the locking mechanism containing gas engine 121, the annular pusher piston 122 of the spring 123, stenobrachius the plunger 124, the compensation pruzina and its emphasis 126, a saddle-focus-plunger 127, bilateral arcuate spring 128, beam bilateral plunger 129, located on the associated with the piston rod racks 130, releasing the protrusion 131, 132 fixed focus and locking 133 wedge gate hooks 114.

At the initial moment of the shot under the action of the powder gases on the piston gas engine 121, when the pressure is not enough to move the bolt, the piston rod through the beam pusher 129 acts on the saddle stops 127 and through it moves the locking wedge 133 under the fixed stop 132, getting jammed the bolt snaps into the locked position. When this ring plunger 122 will compress the spring 129 and will come close to takanohana the plunger 124 and beam pusher 129 under the influence on his right shoulder releasing protrusion 131 disengages with the left ledge saddle stop 127. With further increase in pressure of the powder gases, the piston rod through the ring and stenobrachius plungers 122 and 124 compresses the compensation spring 125 and will move the pusher beam 129 on this left side /drawing/ arched spring 128 acting on the left shoulder pusher beam, turn it clockwise and the right shoulder engages with the right saddle-shaped protrusion of the stop 127.

When the recession pressure p is rogovich gases to a predetermined value of the compensation spring 125 will open and will move the piston rod back to its original position, when this beam pusher 129, acting on the right ledge saddle stops 127, withdraws the locking wedge 133 from under fixed stops 132 and unlocks the bolt hooks 114, which is moving together with the bolt, under the action of the inclined grooves 118 of the receiver will be released from engagement with the locking protrusions 115 and the bolt will be thrown back.

Udarnikov firing device with two firing modes /Fig/ located inside the shutter and the inside of the return spring 6 and is equipped with a drummer 71 from the rear spear tip 72 with placeables annular ledge hammer spring 73, two coaxially arranged sleeves - internal reference 74 and the outer movable 75. On the free end portion of the supporting sleeve mounted on the rear side of the receiver, made of spring clamps 76 leading whispered and 77 whispered timer, and a movable sleeve - terminal fork tabs 78 with slipped on easily on spring leading whispered 76 and change their current length and, consequently, power. The amplitude of longitudinal movement of the movable sleeve 75 is limited by the length of the longitudinal groove 79, made in the wall of the support sleeve 74, which includes a male protrusion 80, mounted on the inner side of the movable sleeve 75.

The mechanism of longitudinal movement of the movable sleeve of the content is it the carriage 81, located inside the supporting sleeve 74, is placed inside on the axis of the spring-loaded plungers 82, made in the form of two shoulders arms, back, shoulders which pass through longitudinal openings in the wall of the supporting sleeve and engages with the slot stops the movable sleeve, and the front shoulders are equipped with end bevels with the possibility of occurrence between them spear tip 72 drummer 71, rotate them due to this axis and excretion rear shoulder from engagement with the slot stops the movable sleeve 75. The carriage 81 is connected with the trigger pull 37 through two shoulders lever 83 and a short rod 84. When the output from engagement with the plungers 82 and a movable sleeve 75 under the action of the spring 85 will move forward and fork lugs 78 will move to the spring leading whispered 76 and reduce their effective length, thereby increasing their strength.

Combat spring 73 is located on the drummer 71 in the middle part of the inside of the guide sleeve 86 immediately adjacent to the head part of the bolt. Guide sleeve 86 in the rear part has a hole, through which passes the pin, and an internal annular ledge, which is the rear stop mainspring 73. On the opposite hand combat spring rests against the front annular projection 87 drummer. On the middle part of the inner surface of the guide sleeve 86 is calcev the first ledge 88, valid when moving the shutter from the rear end position on the annular ledge 87 drummer and liberating his spear tip 72 of the spring grips whispered timer 77.

Firing mechanism operates as follows. When the waste gate in the rear end position when released the trigger spear tip 72 drummer 71 sequentially drops for hooks leading whispered 76, whispered timer 77, is included between the front end bevels two shoulders of the lever pushers 82 and rotates them, bringing them back shoulders out of engagement with the slot stops the movable sleeve 75. Fork lugs 78 slipped over the spring leading whispered, their current minimum length, and maximum power. When reverse motion of the shutter lever pushers again engages with the lugs of the movable sleeve 75, the spring hooks whispered timer 77 capture the spear tip 72 and hold it, resulting combat spring 73 is compressed. Near the front end position of the bolt under the action of the annular ledge 88 on the annular ledge 87 spear tip 72 disengages from hooks whispered timer and is caught by the hooks of the leading whispered 76. At this moment the shutter reaches the front end position, so that the impact annular ledge 8 on the annular ledge 87 drummer stops, the strength of the spring is insufficient to overcome the resistance of hooks leading whispered 76 with reduced current length and the drummer remains cocked.

When the trigger is pulled, the trigger rod 37 will rotate the trigger lever 83 and through an associated short rod 84 will take the carriage 81 ago, and along with it through two shoulders levers-pushers 82 and the sliding sleeve 75. Fork lugs 78 are moved from springs leading whispered 76, the effective length will increase and the resistance force will decrease and now spear tip 72 under the action of the hammer spring 71 is released from the hooks leading whispered 76, will break the capsule and will be shot.

Further work the trigger depends on full or partial rotation of the trigger, which corresponds to a full or partial movement of the carriage 81 ago. In case of incomplete move the carriage back interaction spear tip 72 with two shoulders levers-the pushers 82 is maintained and working mechanisms corresponds to the described technology. This technology determines the mode single shooting. Incomplete rotation of the trigger after executing the shot, you must release the trigger and press it. Under the action of the spring the trigger through the trigger pull 37 and 84, the carriage 81 moves the EAP is red and the rear shoulders of the lever pushers 82 will drop for interlocking lugs of the movable sleeve 75. The trigger mechanism is ready for the next shot.

At full turn trigger the carriage 81 is discharged in the rear end position and the spear tip 72 is not already comes to the front of the lever arms-pushers 82, rear shoulders remain in the slot stops the movable sleeve 75 and hold it in the rear position. Therefore, the spring hooks leading whispered not intercept the spear tip 72 and the drummer after his release from the hooks whispered timer 77 breaks the capsule and produces a shot. When fully pulling the trigger the cycle repeats and implemented by the continuous shooting. After the trigger is released, the striker remains in the position of the combat platoon. The calculation of the power characteristics of the interacting springs is made on the basis of the stated technologies.

Return spring 6 is located inside the shutter /figure 10, 12/ between the rear wall of the receiver and ring-fence, which is the front wall of annular groove formed by the guide sleeve 86 drummer and a side wall of the gate.

The external surface of the device contains the longitudinal and transverse smoothing grooves /flute/forming the exposed area with nozzle orifices, and a layer including ogen ejector shroud in the form of a lattice with ejector nozzles. In the front the front smoothing grooves are made deeper. With the barrel of the device is associated screw belt 105.

The dynamic interaction of the elements considered, the reactive acoustic compensator allows to obtain the following results:

1. To reduce the force of the recoil of the weapon due to the relatively opposite her thrust jet nozzles.

2. To reduce the power of frontal flow of the powder gases through a series-continuous leakage through the jet nozzle.

3. Expand the audio range shot as a set of sinusoidal waves with the largest proportion of energy at the fundamental frequency and move it to a higher part by dividing a wavefront many microprotol with mutually mismatched phases through the use of frequency-converts arrays.

4. To reduce the turbulence of the gas stream at the outlet due to the longitudinal and transverse smoothing grooves /ribs/ on the surface of the device and ejector nasdaw providing a deeper air entrainment gas jets and more efficient mixing, including due to the mismatch of the phases of the gas jets on the frequency-converts arrays.

5. To reduce the level of sound component of the gas flow due to losses in the channels of the frequency-converts arrays.

6. Fell is ü the level of sound energy shot due to the absorption of high-frequency oscillations in the air and reflecting surfaces.

7. Change the directional characteristics of the sound radiation of jet nozzles due to deviations in the opposite direction of the shot side.

When fired, the powder gases, as anticipating the bullet and following it through the Central gas channel, sequentially go through all nozzle chamber, continuously reducing the pressure due to leakage through the jet nozzle. This is a reorganization of the sound component of the gas stream. Several fundamental frequency, which is where most of the energy shot, scattered on the frequency-converts the grids on a wide sound spectrum and shifted to higher frequencies. Energy gas stream is lost in the Central gas channel passing through gas nozzles and diffusers. On the surface level of the acoustic component is reduced both due to the smoothing of grooves and ejector Asadchev, and by reducing the mixing zones in separate gas streams. The latter allow cameras powder gases reached with a large pressure loss, therefore, through the output nozzle and through the front part of the frequency-converts the grid out in the air almost in a laminar mode, not arousing strong sound waves, especially in front of spaziali the grooves /flute/ made deeper.
