The invention relates to firearms handguns weapons, namely revolvers with watershed recharge scheme (the barrel rotates with the drum down without opening the housing). Closest to the invention analogue can be considered released IZHMEH" revolver MP 412 "Rex" with the barrel rotates with the drum relative to the perpendicular to the bore axis. The distinctive feature of this revolver is a composite steel and cast thermoplastics and design, and in fact revolver complicated by the classical scheme of the "Russian Smith-Wesson". Cm. article by Michael Dragunov "the Return of Russian revolver" magazine Rifle No. 4, 2000, p.38-40.

Revolver with watershed recharge scheme (the barrel rotates with the drum down without opening the housing) with simultaneous automatic ekstragirovaniem cartridge contains a barrel, drum shop, body, arm, firing mechanism is double action hammer type, the rotation mechanism and the fixing drum, locking and safety mechanisms.

The disadvantage of this revolver are large dimensions, low weight sbalansiroavnnosti, rapid wear of the hinge joints connecting the barrel with the body.

The aim of the invention is to reduce the overall dimensions of the gun, shoulder recoil, improving the weights of the th balance, improving the reliability of the hinge joints connecting the shaft with the housing, locking and safety devices without increasing the overall weight of the revolver.

The technical problem is solved due to the fact that the revolver with the barrel rotates with the drum without tripping the case with simultaneous automatic ekstragirovaniem cartridges containing barrel, drum shop, body, arm, firing mechanism is double action hammer type, the rotation mechanism and the fixing drum, locking and safety mechanisms, release the clamp according to the invention the trigger guard and the handle is moved forward and upward relative to the shaft and drum, while the trigger guard is under the trunk and the neck of the handle and located in her shock trigger - under the drum, and the gate lock has a lever control and a spring-loaded slider, tab, concatenated with the axis of the drum in the closed position of the barrel with enclosure, lock and trigger are under-barrel box body between the axis of hinge rotation shaft and a cylindrical cavity under the drum, and a spring-loaded slide lock is mounted for locking it in closed position of the barrel and the housing by pressing the trigger.

In addition, the slider of the lock in case of incomplete stroke of the locking barrel to what bosom blocks the trigger, and in its extreme rear position locks the extractor Cam and the axis of the drum is made as one integral part, and performs the function of the extractor rod, and in the closed position of the shaft with the housing axis end enters the hole of the breech ring under the spring force of the slide of the lock.

When the cocking lever, the sear, the dog turning drum and the clamp drum set in the handle, and the cocking lever is connected with a trigger operated, in which there is a ledge leading into effect the release of the drum, and whispered connected with a pull of the trigger earring.

In addition, the dog turning drum installed on a separate starting from a hook on the lever and is actuated from a Cam with a roller mounted on the cocking lever, and a spring pawl fixed in the breech ring body, and on the rear end of the barrel has two lateral protrusion mating with the ledges in the housing, and a tooth with a groove that includes a slide lock, and the Central hole axis of the drum ends fitting with thread.

In the Central hole of the drum with the front end there is a thread, wrapped around a drum fitting of the barrel with the possibility of free rotation, combat coil spring acts to pull the trigger force directed downwards, and the reactive force of the mainspring by means of the lever returns to the similar position of the trigger and the safety bar of the trigger.

In addition, the Cam extractor installed spring-loaded dog, and the total length of the gun is limited to the front end of the stem and the end of the trigger.

Differs significantly from the known models of the barrel, the method of installation and locking of the barrel. Differ significantly from the famous castle of the shutter and the mechanism extractiona sleeves, acting on one lever, the rotation mechanism and the fixing drum, cocking the hammer and drive the safety of the strap remote from the trigger.

The number of original details revolver (without the axes of the pins and screws) - 50. Weight - 900,

Comparing with the revolver MP 412 "Rex" (journal publications) with the same caliber 357 Magnum and the length of the barrel 102 mm from the proposed revolver distinctive parameters are the following:

- overall length is less than 62 mm

- height is less than 25 mm

- shoulder recoil by 15 mm

- significantly shifted to the arm center of gravity, and in the author's opinion should be better strength and ballistic characteristics.

Figure 1. and figure 2 shows the sections and the General appearance of the revolver.

The housing 1 1. - solid steel part that grenade box, gradually expands and moves into the cylindrical recess under the drum, ending in a wall of the breech ring. Under them, not leaving the envelope in length, are the trigger guard and frame rucola the key, and the bottom plane grenade boxes over the trigger guard coincides with the lower generatrix line of the drum and the axis of the trigger is located above this line. The shape and location of the neck of the handle is made so that when gripping the arm segments of the casing and the drum are recessed between the thumb and forefinger of the hand, contributes to this high relative to the drum the location of the trigger. Advanced power components of the case: under-barrel box, segments, covering the drum bottom, the side walls of the neck of the handle allowed to use the open (without detachable frame) case when upper (non-inverted) the location of the shaft relative to the drum. The axis of the hinge barrel shifted forward relative to the drum, which allowed us to apply a longitudinal guide shaft and install the lock bolt between the axis of the hinge and the drum. The hooks 2 figure 2 barrel housing unload hinge at the shot. The shaft 3 1 is made in a single piece (the variant with the receiver coupling) with hinge lugs, front and hole with the groove under the axis of the drum (aka rod extractor), acting at the rear end of the stem in the form of a fitting threaded and smooth neck 4 figure 1. The drum is wrapped around a fitting, then gets free rotation. Thread locks the drum against axial movement disclosed in the m position of the revolver and ekstragirovanie. In the rear part of the trunk in addition to hooks have a tooth 5 1 castle gate. The castle is a slider 6 1, sliding in the slots on the chassis, located in the radial direction from the axis of rotation of the groove in the tooth, under the action of the spring 7 figure 1. The slider has a hole, which includes a lever arm the trigger with a pull of 8 figure 1 during the descent, when the slider is locked in the locked position of the lock, and the descent, if the slide is not fully inserted into the groove of the tooth. Disclosed revolver rotate the lever down and, if the lever is rotated approximately one-half turn, the revolver disclosed without departing from the extractor, with the full rotation of the lever with the output of the extractor, then the lever is released, and the extractor arm is returned into the slot of the drum. With the closure of the trunk with the body slider lock your ledge 11 1 enters the opening in the axis of the drum, the spring force pulls it behind him, and the end of the axis is in the Central hole of the breech ring, the dog 12 1 Cam extractor allows him to occupy its original position. This design cancels its own locking device extractor Cam.

Accordingly, the layout of the revolver arranged firing mechanism is double action and the mechanism of rotation and fixation of the drum. Between the trigger and septula 34 figure 1 has the cocking lever 13 figure 1, combined the with the first thrust of 8 figure 1. On the cocking lever has a roller 15 figure 1, which drives the Cam 16 figure 1 dogs of rotation of the drum 17 figure 1. The dog tightened to the ratchet drum by the spring 18 figure 1 installed still in the breech ring of the housing. Pull 8 1 located actuates the latch drum 19 figure 1. Spring 20 figure 1 draws the clamp to the drum, and the protrusion 21 figure 1 is designed to lock the latch when passing underneath the ledge 14 figure 1 of the cocking lever, that is, when the shutter trigger, and Vice versa blocks the descent, if the latch is not properly seated in the groove of the drum or the drum has not reached a fixed position. The trigger 22 figure 1 is driven by the thrust of 23 figure 1, which is associated with septula earring 24 figure 1. Spiral hammer spring 25 figure 1 rests against the bottom turn in the adjusting nut 26 figure 1, and the top round in the lever 27 figure 1, which is hinged to the plunger 28 figure 1 of the cocking lever and a safety strap 29 figure 1. Thus, the battle reactive spring force returns to its original position, the cocking lever, trigger and a safety bar that separates the trigger and firing pin 30 figure 1. At the top of the breech ring has adjustable for windage sight 31 figure 1. Grip plates fixed axis percussion firing mechanism and is fixed on the frame body side hooks 32 figure 1 and the back plate 33 of figure 1 with one screw.

Action is e revolver.

The right hand holding the handle, the thumb of the left hand to rotate the lever 9 figure 2 before the release of the wedge-shaped tooth of the slide 6 figure 1 from the groove of the housing. Together with the slide will move forward and exit holes of the breech ring, the axis of the drum 35 figure 1. Next, lightly touching the left hand barrel drum is rotated relative to the housing, the extractor is not out of the drum, since the lock lever was not rotated to the stop of the slide lock 6 in figure 1 the Cam extractor 10 figure 1, and is stopped in an intermediate position. Charging the drum and the barrel drum, turning down the tooth 5 1 press the spring-loaded slider, interlocks with the housing snaps into place. Revolver in readiness.

Discharge or extractiona sleeves differs in that the lever 9 figure 1 to turn on to the stop of the slide 6 in figure 1 the Cam extractor, then when the barrel rotates 90° extractor will bring all of the cartridges 20 mm from the end of the drum. To return the ejector to its original position, it is necessary to release the lock lever and light hand pressure to lower the extractor. Holding it in extended position only by friction.

Fires the revolver as well as a traditional double action revolvers. By pressing the trigger through thrust 8 1 rotates the cocking lever 13 figure 1, the sear 34 figure 1, the latch 19 figure 1 and the lever 16 figure 1 soback the 17 figure 1 rotation of the drum. Whispered connected by a shackle 24 figure 1 with a thrust of 23 figure 1 hammer, raises it up, squeezing combat spring 25 figure 1, vvodit the trigger 22 1 till failure and hitting the striker 30 1, i.e. there is a shot of a wound. The cocking lever 13 figure 1 apart from the basic functions by means of the pusher 28 1 rotates the lever 27 figure 1, clutching combat spring from the top through the saddle 37 figure 1, lower the safety bar 29 1 trigger, pivotally connected with the lever 27 figure 1. After the shot the combat spring returns to its original position, the cocking lever, the trigger, the dog turning drum, a safety bar and a hammer. The latch drum applies thrust 8 1 trigger spring-loaded tail. When reverse motion pull down the tail, compressing the spring, moves, passing the ledge thrust, not rosticceria drum.

When firing with the trigger Assembly by the hand mechanism is in the reverse order to install whispered in fighting trim, and the shot will follow after pressing the trigger small effort and progress.

The force on the trigger when firing a wound on the experimental layout, charged primer “revelo”, did not exceed 5kg.
