The invention relates to firearms and particularly to structures of small automatic weapons.

Currently in service with the Russian army is 5.45 mm AK-74.

Machine gun can fire single shots or rapid fire, the queue length is determined by the shooter.

The lack of machine - low efficiency of firing due to the large dispersion of bullets.

A large dispersion of bullets determined by the following factors:

- the recoil after each shot, sending the arrow through the receiver box and butt, periodically moves the system "Rifleman weapons" in space. When the machine moves back and to the side, scattering the trajectory of bullets;

- moving parts of machine (bolt, bolt carrier), moving inside the receiver and against the front and rear positions on the walls of the box, create long-term disturbance, altering the position of the instrument in space;

- low rate of fire rapid fire system "Rifleman weapons" greatly moved, increasing the dispersion of bullets.

Arrows, determining independently the number of shots in the queue, can make from 2 to 5 shots in the queue. The last bullet shots (3, 4, 5) due to the large deviations of the machine in between shots much otklonyayutsya goals and reduce the effectiveness of firing.

The rate of fire of the described machine is not high enough due to the low recovery rate of speed of the reel when the hard blow of moving parts in the back plate.

Known automatic weapons (Eurasian patent No. 000100, publ. 27.08.1998), selected as a prototype, containing movably mounted in the casing of the spring-loaded barrel group, including the barrel and receiver box, exhaust, engine, including the chamber and the gas outlet, a spring-loaded bolt carrier with the bolt, the buffer mechanism, a feeding mechanism, means for feeding the cartridge into the chamber, the percussion mechanism and the trigger mechanism septula.

The weapon is provided with the angular movement of the receiver group relative to the shell and the striking mechanism has a trigger, made movable along the axis of the arms and mounted in the receiver with the ability to interact with the bolt carrier and trigger mechanism comprises a trigger, disconnector with copiers and sear spring-loaded finger, while the trigger is arranged to interact with the disconnector mounted in the casing for movement, copiers disconnector is designed to interact with the spring loaded finger whispered that has the opportunity to interact with the trigger.

In a known machine of the receiver group Amort is optimized and the shot rolled back compressing the spring shock absorber. The locking mechanism consists of a bolt, bolt carrier and recoil.

The trigger mechanism allows for single fire, automatic fire, a series of two shots and continuous fire.

The machine has two rate of fire:

- 1800 rounds per minute for automatic queue a series of 2 shots;

600 rounds per minute for all subsequent shots in the queue.

Venting the engine consists of a gas chamber. A gas chamber is a single entity (a single item) and consists of two tubes connected by a jumper. Tube with a larger diameter zapressovyvajutsja on the trunk. In a tube with a smaller diameter is inserted into the cap to form a cavity. In order for the gas to reach from the trunk to the gas chamber in the barrel, cut the notch.

In the impact mechanism the trigger is moving forward steadily. For reliable firing of the cap on the entire length of the forward trigger coupled to the bolt carrier.

The disadvantage of this machine is a sharp decrease in accuracy of fire of the third and subsequent shots of the queue.

This is because at the end of a series of two shots of the receiver group with the accumulated impulse from two shots strike the casing in its rearmost position. Under the action of impact weapons dramatically pick up, resulting in p is WKR increases the dispersion of all subsequent bullets queue.

Also need to take into account the fact that, in addition to the impact of the receiver group in its rearmost position, there strikes the receiver group in the front position. All these attacks drastically reduce the accuracy of the third and subsequent shots of the queue.

The problem to which the invention is directed, is the reduction of dispersion when firing automatic queue a series of three shots.

The problem is solved constructive implementation of drums and trigger mechanisms for variable rate when shooting bursts, means for repayment of the residual pulses of the barrel and sliding parts, and use the angular movement of the barrel relative to the receiver, that reduce the deviation of weapons in space by shooting. In the claimed invention the increased accuracy is due to the fact that:

- the barrel is made movable, resulting in returns arising from the shot, only affects the trunk and not on all weapons in General;

- the barrel after the first shot hits in the device for the residual maturity of the pulses, which in turn made movable and spring-loaded;

- sliding part after the first and second shots in the extreme rear position of the hit in the device for repayment of the sliding parts, and not in the receiver box is;

- sliding part at the time of the second and third shots in the extreme forward position to hit the trunk;

Assembly under the trunk podruzamevaet the barrel, resulting in the sliding part at the time of the second and third shots in the extreme forward position to hit the barrel, not the receiver box.

The essence of the invention is expressed in the following essential features sufficient to achieve provided by the invention technical results.

Automatic weapons contains movably mounted in the receiver by a spring-loaded barrel, spring-tensioned means to repay the residual pulses of the barrel and sliding parts, exhaust, engine, bolt carrier with the bolt, the guides to the sliding part, Assembly, under the barrel, drums and triggers.

This is due to the fact that the release strap 92 and the disconnector 99 have different angles with different modes translator 109. When auto exhaust is E. the rotation angle of the shutter slats 92 with disconnector 99 less than with a single fire. As a result, the protrusion 60 of the right of stavish 53, located on the bolt carrier 51, passes over the protrusion 102 of the disconnector 99.

A few millimeters to its rearmost position, the rod 123 is cut in the bore 63 of the projection 62, which is located on the left stavishe 52.

In its rearmost position the bolt carrier Assembly 19 and the shutter Assembly 20 through the bearing surface 81 of the trigger 74 interact with the buffer mechanism 118, resulting kick sliding parts 19, 20 and trigger Assembly 69 on the end face of the stopper 121 with a device for the residual maturity of the pulses of the barrel and sliding parts 16.

After hitting the sliding part 19, 20 together with the trigger Assembly 69 and the sleeve 129 under the influence of the return spring 50 and two combat spring trigger (70, 71) are moving forward, while the device for the residual maturity of the pulses of the barrel and sliding parts 16 moves back.

The trigger Assembly 69 when it recovers its latch 75 abuts against the abutment surface 59 of the sealing frame 51, causing the latch 75 is turned to a certain angle.

At the time of the roll shutter Assembly 20 by the end docelowego protrusion 66 retrieves the top round from the magazine 2 and slams it into the chamber of the barrel 6.

In the beginning of the locking shutter Assembly 20, the latch 75, located on the trigger Assembly 69, comes in contact with that is Cetelem Assembly 43, located on the liner 25, causing the latch 75 rotates and comes to its end in the notch 61 of the right of stavish 53, which ultimately provides the coupling of the trigger Assembly 69 of the bolt carrier Assembly 19. Strike the firing pin 65 put together the trigger Assembly 69 and the bolt carrier Assembly 19. There is a second shot.

Hit with sliding parts 19, 20 and trigger Assembly 69 after the 1st shot, a device for repayment of the residual pulses of the barrel and sliding parts 16 rolled back together with the movable sleeve 166 and compresses the spring 165 return mechanism 164. Adatives back to the rearmost position, the device 16 begins to roll forward with the sleeve 166 under the action of the spring 165 return mechanism 164.

After production of the second shot sliding parts 19 and 20 together with the trigger Assembly 69 and the sleeve 129 go back. Similarly, as with the first shot, is a reflection of the sleeve. Due to the fact that the device for the residual maturity of the pulses of the barrel and sliding parts 16 after the first shot was rolled back, sliding parts 19, 20 with the trigger Assembly 69 and the sleeve 129 after the second shot rolled back already at a greater distance.

A few millimeters to its rearmost position, the rod 123 is cut in the bore 63 of the ledge 62, situated on the left is stavishe 52.

In its rearmost position the bolt carrier Assembly 19 and the shutter Assembly 20 through the bearing surface 81 of the trigger 74 interact with the buffer mechanism 118, resulting kick sliding parts 19, 20 and trigger Assembly 69 on the end face of the stopper 121 with a device for the residual maturity of the pulses of the barrel and sliding parts 16.

After hitting the sliding part 19 and 20 together with the trigger Assembly 69 and the sleeve 129 under the influence of the return spring 50 and two combat spring trigger (70, 71) are moving forward, while the device for the residual maturity of the pulses of the barrel and sliding parts 16 moves back. In the reel of the sliding parts 19, 20, trigger Assembly 69 and sleeve 129 happen the same processes that are similar to forward the first shot.

The barrel 6 after the second shot is slightly shifted ago. Under the influence of return spring 28, the shaft 6 in the future, returns to its original position.

The sliding part 19, 20 with the trigger Assembly 69 and the sleeve 129 reach the extreme front position. Strike the firing pin 65 put together the trigger Assembly 69 and the bolt carrier Assembly 19. The third shot. Sliding parts under the action of return and work BGD go back.

Hit with sliding parts 19, 20 and trigger Assembly 69 after the second shot, a device for repayment of the residual pulses of the barrel and sliding parts 16 rollback is provided for backward together with the movable sleeve 166 and compresses the spring 165 return mechanism 164. Adatives back to the rearmost position, the device 16 begins to roll forward with the sleeve 166 under the action of the spring 165 return mechanism 164.

This device 16 has time to come is in forward position before sliding part 19, 20 with the trigger Assembly 69 and the sleeve 129 has time to fully recover. A joining device for the residual maturity of the pulses of the barrel and sliding parts 16 in the front end position is accompanied by a shot of this device 16 on the receiver box 1. So at this point, the device 16 through the switch 128 acts on the ledge 163 of the latch shaft 158. From the applied load latch shaft 158 rotates and releases the barrel 6. The shaft 6 under the action of its return spring 28 moves forward and rests in front ledge 162 of the latch shaft 158.

Sliding parts 19, 20 and the trigger Assembly 69 after the third shot also hit the end of the limiter 121 with a device for the residual maturity of the pulses of the barrel and sliding parts 16.

As for subsequent shots in the queue, then it is possible to note the following:

- sliding part 19 and 20 together with the trigger Assembly 69 will always hit the end of the limiter 121 with a device for the residual maturity of the pulses of the barrel and sliding parts 16. The difference from shot to shot will only be in the om, at what point will kick sliding parts 19, 20 and trigger Assembly 69 on the end face of the stopper 121 with a device for the residual maturity of the pulses of the barrel and sliding parts 16;

interaction between sliding parts 19, 20 of the trigger Assembly 69 and sleeve 129 in all subsequent shots after the second will be identical to each other according to the degree of interaction of the parts with each other and with other parts and mechanisms;

the shaft 6 after each shot will have a slight offset, but under the influence of return spring 28 will return.

Automatic weapons, in the fuse

For transfer of automatic weapons in this position translator 109 is installed in the third slot shaped grooves 111 and 112 in the housing of the trigger mechanism 82 and the receiver 1. Together with the translator 109 moves the trigger strap 92 and the disconnector 99.

As a result, the inability of the shot is on 5 parameters:

- rear projection 107 shutter slats 92 comes under the tail 89 whispered 84, causing the sear 84 cannot rotate;

the lower ledge 108 shutter slats 92 rises flush with shaped ledge 83 located on the housing of the trigger 82, resulting in the release strap 92 cannot rotate;

- rear projection 107 shutter slats 92 comes into the cutout 9 of the trigger 90, in the result, the trigger 90 cannot rotate;

- there is no point of contact of the support surface 88 whispered 84 with the contact surface 101 of the disconnector 99 and the guide 104, located on the axis 103;

- there is no point of contact between the lip 95 of the lever 93 and the lower ledge 108 of the trigger strap 92.

Thus, the claimed invention in comparison with the prototype improves the efficiency of firing, i.e. the increase in the number of affected targets for the same number of shots.

The decrease in dispersion when firing automatic queue a series of three shots in the claimed invention is achieved by that:

- the barrel is made movable, resulting in returns arising from the shot, only affects the trunk and not on all weapons in General;

- the barrel after the first shot hits in the device for the residual maturity of the pulses, which in turn made movable and spring-loaded;

- sliding part after the first and second shots in the extreme rear position of the hit in the device for the repayment of the residual pulses sliding parts, and not in the receiver box;

- sliding part at the time of the second and third shots in the extreme forward position to hit the trunk;

Assembly under the trunk podruzamevaet the barrel, resulting in sliding hour and at the time of the second and third shots in the extreme forward position to hit the barrel, and not in the receiver box.
