Abstract

FIELD: systems of automatic weapon, weaponry and systems of automatic small arms. SUBSTANCE: the oblique-grooved device for bore locking has two modifications: with one kinematic pair within the drive and driven links, and with two kinematic pairs within two drive links and a driven link with a two-sided engagement located between them. The links have bulges and grooves inclined relative to the breechblock longitudinal axis. Engagement of the links and locking of the breechblock are effected when the bulges enter the conjugate grooves and blockings of the driven link in the position of complete engagement of the links. The trigger mechanism with control of the modes of firing through the trigger does not need any use of a special change lever to pass from single-shot fire to continuous fire. Fire control is effected by changing the trigger stroke. At an incomplete pressing of the trigger single-shot fire is conducted, at a complete pressing - continuous fire. To ensure an absolute reliability of conducting of single-shot fire, the trigger mechanism is provided with a keeper of the mode of firing. At a pressed pedal the possibility of complete pressing of the trigger is blocked. The machine gun with a balancing gear has four modifications formed by two methods for cartridge feed-belt-feed and magazine-feed ones, and by two methods of breechblock unlocking a compensation one and with a direct drive from a gas engine. The compensation method of breechblock unlocking is featured by the initial period of the shot counteracts the force of pressure of powder gases and ensures a delay of the moment of breechblock unlocking in accordance with the weapon ballistic requirements. In the compensating mechanism of breechblock unlocking use is made of a low-power gas engine operating for compensating spring compression only. Automatic action of the weapon is effected due to the half-free breechblock. In the machine gun modifications with breechblock unlocking directly from a gas engine automatic action of the weapon is effected due to the use of the energy of powder gases rejected from the bore to the gas engine with a drive mechanism to the breechblock. In all machine gun modifications use is made of a device for balancing of the masses of the weapon movable parts, making it possible to prevent the influence of impact moments of the loading mechanism on fire. In machine gun modifications with a magazine feed of cartridges use is made of a longitudinally multiple- row magazine with a doubled capacity as compared with a box standard magazine. To provide the universality as far as the ammunition stock is concerned, the machine gun is provided with a magazine adapter which make it possible to use also drum-type and box magazines beside the longitudinally multiple-row one. EFFECT: simplified automatic action of the weapon, reduced weight of the weapon and enhanced adaptability to its manufacture. 53 cl,10 dwg, 1 ex

Description

 The invention of a machine gun with a balancer relates to the field of automatic small arms.

 Famous Kalashnikov machine gun with a tape feed of cartridges / Manual on a small business. - M .: Military Publishing House, 1987, p. 351-394 /. The machine gun comprises a barrel, a receiver, a cartridge receiver, a bolt carrier, a cartridge extractor from a belt, a gas engine, a bolt, a return spring with a guide rod, a trigger, a bipod, or a machine tool. The supply of ammunition in the receiver is made of a metal tape laid in a box, mounted on an arm on the underside of the breech gun. Automation of the machine gun operates on the basis of using the energy of powder gases discharged from the bore to the gas engine with a drive rod to the bolt frame. Locking and unlocking the shutter is made by turning it around the longitudinal axis under the action of the bolt frame using combat projections and combat stops of the shutter and receiver. The trigger sear interacts with a platoon located on the underside of the slide frame. The trigger mechanism of the machine gun serves to hold the bolt on the axial platoon, lowering it from the combat platoon and putting it on the fuse. The drummer interacts with the slide frame and has no mainspring.

 The technical result of the claimed invention is to increase the combat effectiveness of the machine gun, reducing weight, improving manufacturability and reducing the cost of production.

 The specified technical result is achieved by the fact that the functioning of the automatic machine gun is ensured by shuttle movements of the half-free shutter under the influence of powder gases after it is unlocked through a gas engine with a compensation mechanism for delaying the release moment of the shutter or without it directly through the piston rod of the gas engine, used as a locking device kinematic pair with oblique engagement, the use of mass balancing devices of the moving parts of the gun.

 The claimed invention differs from the known weapon in that it comprises a locking device with an oblique engagement, a unlocking device with a compensating mechanism for unlocking the shutter, a belt feeding mechanism with a shutter drive, a jumping cartridge bridge, a cartridge feed lever for the sending line with the combined function of the hammer of the projectile firing pin with a mainspring located inside the bolt, mass balancer of moving parts, balancer with cocking, flat return spring, trigger m cooperating with cocking balancer reflective stem disposed within the valve.

 The reduced weight of the inventive machine gun is the result of the lack of a bolt carrier with a powerful gas drive. In the claimed invention uses a gas engine, however, significantly less power and with a different purpose. It serves only to disengage the spring-loaded lock from the locking ledge of the driven link in the extreme locking position.

 Improving the combat effectiveness of the claimed invention is a consequence of the use of mass balancing devices for moving parts. The use of this device can significantly increase the stability of the weapon during firing, to exclude the impact on the shooting of shock pulses of moving parts in extreme positions and reduce scattering. The high stability of the weapon, the absence of oscillations creates the possibility of effective use of an optical sight on it, which will significantly improve the accuracy of aiming, and will effectively hit small targets, such as loopholes, viewing slots of armored vehicles, etc. In addition, comfortable conditions are created for the shooter, which has great psychophysical significance.

 Lower production costs and higher manufacturability are associated with a certain decrease in the number of complex parts, and especially with the absence of a shutter frame with a large number of conjugate curved surfaces.

The essence of the invention is illustrated by drawings, which show:
Figure 1 - Machine gun, the composition of the mechanisms.

 Figure 2 - Handle reloading.

 Figure 3 - Receiver cartridge tape.

 Figure 4 - Shutter with a locking mechanism.

 The locking device is a kinematic pair with oblique engagement. Inclined protrusions 1 of the driving link are located in front of the shutter 2 and are made together with it. The inclined slots of the driven link are located on the inner surface of the hub 3 / Fig. 1, 4 /, located between the annular stop 4 of the weapon body and the breech section of the barrel. When the kinematic pair is engaged, the protrusions of one link enter the inclined grooves of the other link, while the drive link, which has freedom of only longitudinal movement, kind of screws on the driven link, which has freedom of only lateral movement. When the kinematic pair is fully engaged, the freedom of the lateral movement of the driven link at the initial stage of the shot is blocked by the end position lock - the movable stop 5, as a result of which the driving link loses the freedom of longitudinal movement, i.e. shutter locks.

 The automatic unlocking mechanism of the shutter 2 comprises a gas engine 6 with a piston rod 7, a movable frame 8, a compensation spring 9 located together with its stop 10 inside the movable frame, a spring hook 11 rigidly connected to the movable frame, inclined copy protrusions 12 located on the spring the hitch 11, the copy pins 13, the thrust rod pusher 14. The thrust rod 14 has a trailing protrusion at one end, beyond which the hook 11 slides. Its other end part interacts with the end push rod 15 (Fig. 2/) pulling 16. The middle part of the rod-pusher 14 is connected with the position lock - movable stop 5 of the hub 3. To return to its original position, the rod-pusher 14 is equipped with a spring 17.

 The manual shutter release mechanism comprises a carriage 18 / Fig. 2/, moving in the longitudinal guides of the weapon body / not shown /, equipped with a leading protrusion 19, interacting with the driven protrusion 20 of the shutter. On the adjacent leading ledge 19, the side / outer / the carriage has a stand 21 for hinging the reloading handle 16 and the spring 22. The reloading handle is equipped with a rotation limiter 23. When the bolt is retracted, the reloading handle is rotated at a certain angle allowed by the rotation limiter 23 and its lower shoulder with the pusher 15, acting on the rod-pusher 14, brings the movable stop 5 out of engagement with the locking ledge of the hub 3 and unlocks the shutter.

 The cartridge belt feed mechanism is shown in FIGS. 1, 3. It is a conventional receiver for moving the belt, and does not have features except for the feeder drive 24, the arrangement of which is shown in FIG. 1 by dashed lines. The feeder drive consists of a spring-loaded single-arm longitudinal lever 25 with an upper inclined edge located under the shutter, and a pusher 26 located on the lower side of the front of the shutter. When the shutter moves back, the pusher 26, running onto the inclined face of the longitudinal arm 25, lowers its front part down and, acting on the lower arm 27 of the feeder 24, rotates the feeder counterclockwise (according to the drawing), as a result of which the cartridge strip moves one link to the left .

 The jumping cartridge bridge 28 is shown in FIGS. 3, 4. It serves to support the bottom of the cartridge sent by the bolt to the chamber. The cartridge bridge is a spring-loaded longitudinal panel that interacts with the bolt through the cam kinematic connection in such a way that when the bolt moves to the rear position, it is located in its place along the sending line and supports the front part of the cartridge being sent until the cartridge reaches the chamber, after of which the shutter, acting on the cam cut of the panel, shifts it down (for itself) and completely sends out the cartridge. The upper position of the cartridge bridge is shown in figure 3.

 The lever 29 for supplying cartridges, in addition to its regular function, also plays the role of a whispered combat platoon 30 of the striker 31 (Fig. 4). When the shutter is moved to the forward position, the lever 29 catches the cocking unit 30, while the shutter continues to move forward, as a result of which the mainspring 32 is compressed. When the shutter reaches the front extreme position, the lever 29 is disengaged from the striker cocking by the wedge-shaped protrusion 33 of the shutter on the trigger pin 34, located on the end of the lever 29. The drummer 31, as can be seen from the drawing (figure 4), is located inside the bolt, which has a longitudinal through groove 35 in the upper wall for moving the combat cock 30.

 Instead of a fixed wedge-shaped protrusion, rigidly connected with the bolt to disengage the combat cock 30 and the cartridge supply lever 29, it is possible to use a movable trigger wedge moving in the upper part of the bolt along guides with limiters of its movement at the end parts. Since the trigger wedge has a certain mass, during shutter movements with great acceleration, trying to maintain a state of rest at the beginning of the movement, the trigger wedge will always be located in the rear parts of the guides relative to the direction of movement of the shutter. When the shutter stops in the front extreme position, the trigger wedge will continue to move along the guides under the action of inertial forces and, having moved its wedge-shaped part under the trigger pin 34, the lever 29 will release the supply of cartridges from the engagement with the combat cock 30 of the hammer 31, as a result of which a shot will be fired.

 The mass value of the trigger wedge should be such that the force of its action on the trigger pin 34 is sufficient to remove the lever 29 for supplying cartridges from engagement with the combat platoon 30.

 Since it takes a certain amount of time to move the trigger wedge from one extreme position to another, the use of such an inertial mechanism will increase the interval between shots. Thus, the trigger wedge simultaneously serves as a moderator of the rate of fire.

 The mass balancing device for the moving parts comprises a balancer 36, gear racks 37 of the shutter and 38 balancer and a gear wheel 39 interacting with them. The balancer is equipped with a machine gun platoon 40 interacting with the trigger mechanism. The balancer is simultaneously a pusher of the return spring 41, consisting of a multi-package assembly of arcuate leaf springs.

 The reflection mechanism of the sleeves includes a rod 51 (figure 4) with a ridge 52 (figure 1) and a stationary reflective protrusion (not shown) of the receiver. The rod 51 is located in a longitudinal hole inside the front of the bolt parallel to the elongated striker of the hammer 31 on the opposite side of the ejector ejector relative to the axis of the bolt. The comb 52 is located in a through longitudinal groove of the shutter wall with the possibility of longitudinal movement and protrudes above the shutter wall to the height necessary for interaction with the reflective protrusion.

 When the shutter moves forward, the bottom part of the cartridge being sent drowns the rod 51 into the longitudinal hole of the shutter, and therefore the ridge 52 of the rod 51 in the longitudinal through groove is shifted back. After the shot, the hook of the ejector 50 will remove the sleeve from the chamber, the ridge 52, when the shutter moves backward, will encounter the reflective protrusion of the receiver, as a result of which the rod 51 will move forward, strike the edge of the sleeve opposite from the ejector hook and throw it out.

 The trigger mechanism includes a trigger lever 42 with a spring 43, a trigger with a hook 44 that interacts with the trigger lever 42, and a fuse 45.

 The considered devices and mechanisms of the inventive machine gun interact as follows. During the initial loading, it is necessary for the reloading handle 16 to take the bolt back to failure, putting the balancer 36, and therefore the bolt on the cock, then return the reloading handle to its original position.

 1. When the bolt is retracted back, the reload handle 16 will initially rotate by a certain angle (approximately 20 degrees) and with its lower pusher arm 15, acting on the pusher rod 14, will move the movable stop 5 out of engagement with the hub 3 of the follower link, as a result of which the hub of the driven link will receive freedom of lateral movement. In this case, the spring 17 is compressed.

 2. The leading link, moving together with the bolt back, with its inclined projections 1 will turn the driven link around the longitudinal axis and will disengage from it. The driven link in this extreme position will be blocked by a double-sided spring lock / not shown /.

 3. The extractor 46 with its hooks will remove the cartridge from the tape and move it back, while the cartridge will raise the lever 29 up; the cartridge, having reached the bottom of the sleeve to the feed ridge 47, under the influence of its bevel and spring-loaded lever 29 will lower down in front of the bolt, and the front of the cartridge - on the cartridge bridge 28 that has moved upwards.

 4. When moving back the bolt with its lower pusher 26, acting on the upper inclined face of the longitudinal arm 25, it will shift its front part down and through the lower arm 27 of the feeder 24 will turn the feeder counterclockwise; feed finger 48, resting on the link of the tape, will move it to the left / according to the drawing / and install the next cartridge against the hooks of the extractor 46; the spring-loaded upper fingers 49 will jump over the next link and hold the tape in the receiver from shifting back.

 5. The backward movement of the shutter through the gear racks 37 and 38 and the gear wheel 39 will be transmitted to the balancer 36, which, compressing the return spring 41, will occupy the front extreme position; the trigger lever 42 under the action of its spring rises up and pops over the cocking position 40 of the balancer 36.

 The machine gun is loaded. For arming, it is necessary to move the bar 45 back under the trigger lever 42, as a result of which it will lose the ability to get out from under the cocking of the balancer.

 When you press the trigger, the following actions will occur.

 1. The trigger with its hook 44 will release the trigger lever 42 from the engagement with the cocking 40 and the return spring 41 will throw the balancer 36 back, and the shutter 2 forward.

 2. The bolt, moving forward, will withdraw the cartridge from under the lever 29, the lever under the action of its spring will drop to the top edge of the bolt and stand in the way of the cocking cock 30 of the striker 31, as a result of which its combat spring is compressed; however, with the bolt moving forward further when it reaches the front extreme position, the wedge-shaped protrusion 33, acting on the trigger pin 34, will raise the lever 29 up and out of engagement with the cocking 30 of the striker 31.

 3. In the forward position of the shutter, the inclined projections 1 of the driving link will enter the inclined grooves of the hub 3 of the driven link and turned counterclockwise, as a result of which the links will mesh; the movable stop 5, under the action of the spring 17, will drop behind the locking ledge of the hub 3 of the driven link and its prohibition, as a result of which the driving link and, consequently, the shutter will be locked; the hammer striker will break the capsules and a shot will occur.

 4. Powder gases passing through the gas hole in the barrel will actuate the gas engine 6, which through the piston rod 7 will move the movable frame 8 back and compress the compensation spring 9; together with the movable frame, the spring hook 11 will also move back, while the copier pins 13, escaping from the inclined copier protrusions 12, will engage the hook 11 with the traction protrusion of the traction pusher 14.

 5. After the pressure in the barrel is reduced to a predetermined value, the compensation spring 9 will be unclenched and move forward the movable frame 8, the spring hook 11 and the push rod 14 which is engaged with it, which, acting on the movable stop 5, will disengage it from the follower link and unlock the shutter.

 6. The leading link, moving together with the bolt back, with its inclined protrusions 1 will turn the hub 3 of the driven link around the longitudinal axis and will disengage from it. The driven link in this extreme position will be blocked by the end position lock / not shown /.

 7. The shutter, moving backward, with the hook of the ejector 50 / Fig. 4/ will remove the sleeve from the chamber; the reflective rod 51, having encountered its crest 52 on the reflective protrusion / not shown / of the receiver, will strike at the opposite end of the sleeve from the ejector hook and throw it out.

 Further, the considered automation cycles of the claimed machine gun will be repeated until the trigger is released.

 The invention - a machine gun with a balancer relates to the field of automatic weapons.

 Famous Kalashnikov machine gun with a store supply of cartridges / Manual on a small business. - M .: Military Publishing House, 1987, p. 235-279 /. The machine gun contains a barrel, receiver, bolt, bolt, return spring, trigger mechanism, sights, butt and bipod. Automation of the machine gun operates on the basis of using the energy of powder gases discharged from the bore to the gas engine with a drive rod to the bolt frame. Locking and unlocking the shutter is made by turning it around the longitudinal axis under the action of the bolt frame using the combat protrusions of the shutter and the combat stops of the receiver. The trigger mechanism is used to pull the trigger from a combat platoon or from a self-timer platoon, strike a striker, change the firing mode, prevent a shot with an unlocked shutter, and set it to a fuse.

 The technical result of the claimed invention is to increase the combat effectiveness of the machine gun, reducing weight, improving manufacturability and reducing the cost of production.

 The specified technical result is achieved by the fact that the functioning of the automatic machine gun is ensured by shuttle movements of the half-free shutter under the influence of powder gases after it is unlocked through a gas engine with a compensation mechanism for delaying the release moment of the shutter or without it directly through the piston rod of the gas engine, using as a locking devices of a three-link mechanism with two kinematic pairs with oblique engagement, mass balancing devices under mobile parts of the gun and the longitudinally multi-row magazine.

 The claimed invention differs from the known machine gun in that it comprises a locking device with oblique engagement, a unlocking device with a compensation mechanism for delaying the release of the bolt, a trigger mechanism with control of firing modes Talco through the trigger, a device for balancing the masses of moving parts, a flat return spring, a mechanism sending rounds from a longitudinally multi-row magazine and a longitudinally multi-row magazine.

 The reduced weight of the weapon is a consequence of the lack of a bolt carrier with a powerful gas drive. In the claimed invention uses a gas engine, however, significantly less power and with a different purpose. It serves only to remove the spring-loaded latch - the movable stop from engagement with the locking ledge of the driven link in the extreme locking position.

 Improving the combat effectiveness of the claimed invention is a consequence of the use of mass balancing devices for moving parts. The use of this device can significantly increase the stability during firing, to exclude the impact on the shooting of shock pulses of moving parts in extreme positions and reduce scattering.

 Lower production costs and higher manufacturability are associated with a certain decrease in the number of complex parts, and especially with the absence of a shutter frame with a large number of conjugate curved surfaces.

The essence of the invention is illustrated by drawings, which show:
Figure 5 - Machine gun, the composition of the mechanisms.

 6 - The mechanism of fire control.

 7 - Handle reloading.

 The locking device is a three-link mechanism with two kinematic pairs containing two oncoming driving links, made in conjunction with one of the shutter, the other with the breech of the barrel, and the driven link located between them. The links of the mechanism contain protrusions and elongated grooves inclined relative to the longitudinal axis. The driven link is made in the form of a hub 3 with bilateral engagement, the protrusions and grooves of which are made on the inner surface. The engagement of all three links occurs when the protrusions of one link enter the inclined grooves of the other link when the shutter 2 moves to the front end position. In Fig. 5, the lines of the invisible contours of the inclined grooves are shown by dashed lines. When the links come closer, the hub of the driven link is sort of screwed onto the leading links of the shutter and barrel. The position of the full engagement of the links is fixed by a movable stop 5, which pops up under the action of the spring 17 behind the stop ledge of the hub, and the shutter is in the locked position.

 The automatic unlocking mechanism of the shutter comprises a gas engine 6, a compensation spring 9, a movable frame 8, an emphasis on the compensation spring 10, a spring hook 11, rigidly connected to the movable frame 8, inclined copy projections 12, the copy pins 13 located on the tooth of the spring hook 11, and traction pusher 14. At one end of the traction pusher 14 a movable stop 5 is made, two protrusions are located on the other, one for engagement with the tooth of the spring hook 11, the other protrusion 53 for engagement with the reload handle.

 The manual shutter release mechanism comprises a reload handle 16 / FIG. 7 /, located on the axis on the rack 21 of the pusher of the shutter 18, interacting with the protrusion 20 of the shutter. 5, the projection of the reload handle is shown by dashed-dotted lines. The reloading handle has a spring 22, a rotation limiter 23 and a pusher 15. When the bolt is retracted back, the reloading lever 16 is rotated by a certain angle allowed by the rotation limiter 23, and with its lower arm with the pusher 15 disengages the movable stop 5 from the engagement with the stopper ledge of the hub 3 of the driven link and unlocks the shutter.

 The trigger mechanism (Fig. 5, 6) is intended for descent of the striker from a combat platoon, control of single and continuous firing modes. A feature of the trigger mechanism is the way to control firing modes through the trigger. When the trigger is incompletely pressed, a single firing mode is provided; when fully pressed, the continuous firing mode is provided. The trigger mechanism contains a firing pin with a mainspring located inside the bolt, a cocking platoon 30 of the striker, the crest of which moves in the longitudinal through groove of the upper wall of the bolt, a trigger 54 with a spring, a firing limiter 55, a trigger chain 56, consisting of two levers, trigger rod 57, the end of which is connected to the firing control panel 58, moving in guides above the shutter. On the firing control panel, there is a control mechanism for the leading sear 59 and the striker 60 catcher. The leading whisper and the platoon catcher are made in the form of two shoulders levers located on the stand 61, and the leading whisper 59 is somewhat shorter than the platoon catcher. Their right / drawing / shoulders contain lateral protrusions 62, 63, interacting with the firing control panel 58. The lead sear interacts with the copy path formed by a cutout 64 to the protrusion 65 of the firing control panel, while moving it longitudinally, and the combat platoon catcher 60 interacts with trigger lever 66, mounted on an axis on the firing control panel. The trigger lever 66 on the right / according to the drawing / end part has a roller 67 that interacts when moving to the left with the protrusion 68 of the shutter, and when moving to the right with a fixed protrusion 69 of the weapon body.

 The mass balancing device of the moving parts comprises a balancer 36, gear racks 37 and 38 located on the shutter and balancer, and a gear wheel 39 interacting with them.

 A flat return spring 41 is located above the bolt and barrel and contains a multi-package assembly of arcuate leaf springs and a stop-slider connected to the balancer, through which the balancer removes the return spring when fired.

 The suction mechanism comprises three spring-loaded longitudinal feeders 71 located on the lower side of the shutter, and a guide cartridge bridge 72 located in front of the front section of the longitudinally-row magazine 73.

 The reflective mechanism of the machine gun consists of a longitudinal rod located inside the bolt in such a way that its front end part interacts with the edge of the sleeve opposite the ejector engagement, and its crest 52, which moves in the longitudinal through groove of the bolt and interacts with the reflective protrusion (not shown) / receiver.

 The fuse is located above the trigger. It is a single-arm lever 74 with an angular hook on the free end and has two positions. In the lower position shown in figure 5, the lever prevents the trigger 54 from moving, in the upper position of the lever, its hook is disengaged from the trigger.

 The sighting device of the machine gun consists of two racks connected by a jumper. There is a front sight on the front desk, and a sight on the rear desk. The sight has a moving rear sight with a slot for aiming and a mechanism for entering corrections in distance and direction. Corrections are entered using two handwheels 75 located on the side of the rear pillar. On the rear side of the rack facing the arrow, there is a correction scale. Racks with a jumper serve simultaneously as a mounting point for an optical sight.

 The machine gun is equipped with a counter 76 remaining cartridges in the store. The drive rod 77 of the counter interacts with the hub 3.

 Longitudinally multi-row magazine 73 contains interacting cartridge sections, equipped with devices for blocking the supply of cartridges in the upper horizontal row of the sections that are next in order in the presence of cartridges in the presence of cartridges in the previous section.

 The machine gun is designed to use a longitudinally-row three-section store for 60-70 rounds. However, standard box and drum single-row magazines can also be used in it. For this purpose, an adapter 79 is provided in the machine gun (FIGS. 5, 10), comprising a fastening mechanism for single-row magazines.

 The adapter consists of two carriages, front and rear, which move along the guide grooves made on the inner side of the walls of the installation window of the longitudinally multi-row magazine. The carriages are the front and rear walls that form the installation window for single-row magazines in the area of any section of a longitudinally multi-row magazine. For fixing at the selected positions, the carriages are equipped with spring-loaded latches, which are released from the engagement with the walls of the installation window of the longitudinally multi-row magazine by pressing handles.

 When using a longitudinally multi-row magazine, the front carriage is moved to the front extreme position, and the rear carriage retracts into the internal niche of the stock. When using single-row box or drum magazines, the carriages form an installation window identical to the installation window of the prototype. In FIG. 5, 10, the rear carriage is shown in two positions in the butt recess (dashed lines) and in the middle section area (dashed lines). The front carriage forms the front wall of a longitudinally multi-row magazine and is not shown in the drawings.

 The considered devices and mechanisms of the inventive machine gun interact as follows. During the initial charging, it is necessary for the reloading handle 16 to take the shutter back to failure and release it.

 1. The reloading handle will rotate at a certain angle allowed by the rotation limiter 23, and its lower shoulder with a pusher 15, acting on the protrusion 53 of the thrust-pusher 14, will withdraw the movable stop 5 from engagement with the stop ledge of the hub 3 of the driven link. The shutter unlocks.

 2. Under the action of the reloading of the shutter pusher 18 connected to the handle on the protrusion 20, the shutter will begin to move backwards, as a result of which under the influence of the protrusions of the leading links on the inclined grooves, the hub 3 of the driven link will begin to move in the longitudinal direction and rotate around its axis, disengaging (making up) with leading links. A spring clip (not shown) will mesh with the hub 3 and lock it in the extreme position for the cyclic shutter stroke.

 3. Longitudinal feeders 71 pop over the trailing edges of the cartridges in all sections of the longitudinally multi-row magazine; the platoon 30 will move with the bolt to the rear extreme position and will drop behind the leading sear 59.

 4. The balancer 36 under the action of the gear racks 37 and 38 and the gear 39 will move to the front position and compress the return spring 41.

 5. Having reached the rear extreme position, the shutter under the action of the return spring 41 will begin to move forward. During the reverse stroke, the shutter will send the upper cartridge of the front section to the chamber, move the cartridges from the middle section to the front, from the rear section to the middle, and the cartridge of the next second row will take the place of the moved cartridge in the rear section.

 6. The leading sear will stop the cocking unit 30, as a result of which, when the bolt moves further forward, the hammer spring will compress.

 7. The projections of the links will go into the mating grooves and the hub 3 of the driven link, having depressed the spring clip, will screw onto the leading links of the barrel until they are fully engaged; the movable stop 5 pops over the retaining ledge of the hub 3 and the prohibition of it, and therefore the shutter.

 The machine gun is ready to fire.

 Single shooting is performed when the trigger is incompletely pressed. As an indicator of incomplete depression, a spring limiter of the firing mode 55 is used, which at the end of incomplete depression of the trigger provides additional resistance. To ensure the absolute reliability of a single shot, the machine gun is equipped with a firing limit pedal located on the left side of the handle. When you press the pedal with the thumb of your right hand without changing the grip of the weapon, the spring limiter of the firing mode 55 with the pusher 78 connected with the pedal is fully extended and prevents the trigger from being fully pressed. When the trigger is incompletely pressed, the interaction of the devices and mechanisms of the machine gun will be as follows.

 1. The firing control panel 58 will shift to the left / according to the drawing /, the roller 67 will escape from the stationary protrusion 69 and the trigger lever 66 will turn clockwise, but the position of the catcher 60 of the combat platoon 30 will not change, since its left end part is located on top of the combat platoon; as the firing control panel is moved further, the host whisper 59, acting on its right shoulder with the protrusion 65 of the copier road, will turn clockwise and will disengage from the cocking, resulting in a shot.

 2. When fired, the powder gases, entering the gas engine through the gas hole in the barrel, compress the compensation spring 9 through its piston and rod and move the movable frame 8 and the spring hook 11 connected to it, backwards, while the copier pins 13 run off along the inclined copier protrusions 12, enter the tooth of the hook 11 into engagement with the end protrusion of the rod-pusher 14.

 3. After the pressure drop in the barrel to a value less than a predetermined threshold, the compensation spring 9 will be unclenched and, together with the movable frame 8 and the spring hook 11, will move the push rod 14 forward, as a result of which the movable stop 5 will come out of engagement with the stop ledge of the hub 3 of the follower link and unlock the shutter; the copying pins 13, having run onto the inclined copying protrusions 12, will bring the spring hook out of engagement with the push rod 14.

 4. The comb 52 of the reflective rod, upon encountering the reflective protrusion of the receiver / not shown /, will strike at the opposite edge of the bottom of the sleeve from the ejector hook and throw it out.

 Further, the devices and mechanisms of the machine gun interact in the same way as during the initial loading, except that the combat platoon 30 will be stopped not by the lead sear 59, but by the catcher 60.

 In order to fire the next shot, release the trigger and press it again. When the trigger is released, the firing control panel 58 will shift to the right / according to the drawing /, the side protrusion 62 of the leading sear will move from the protrusion 65 of the copy path to the notch 64, as a result of which the leading sear will turn counterclockwise and its end part will stand against the military platoon 30; the roller 67 of the trigger lever 66, having run onto the stationary protrusion 69, will turn counterclockwise and disengage the catcher 60 from the engagement cock, which, having moved a little forward, will engage with the drive sear 59.

 When the trigger is fully pressed, the firing control panel 58 will move even further to the left extreme position. The presenter whispered 59 under the action of the protrusion 65 of the copy path after the first shot will remain in the raised position, and firing control will move to the movable protrusion 68 of the shutter. When the bolt reaches the front extreme position, the protrusion 68 will move under the roller 67, which will cause the trigger lever 66 to turn counterclockwise and disengage the catcher 60 from the engagement cock 30, as a result of which a shot will occur. This kinematic pattern will be repeated and will provide continuous firing until the trigger is released.

 The machine gun is designed to use a longitudinally-row three-section magazine for 60-70 rounds. However, standard 40-round cartridges and drum magazines can also be used in it. For this purpose, an adapter 79 / Fig. 5/ is provided in the machine gun, comprising a fastening mechanism for single-row magazines moving along longitudinal guides along the butt of the magazine. When using a longitudinally multi-row magazine, the adapter is shifted to a niche located in the end of the butt. When using single-row box or drum magazines, the adapter moves, for example, to the zone of the second section of the longitudinally multi-row magazine and is fixed in this position by a latch. In the case of single-row magazines, the first cartridge is sent to the chamber after twisting the shutter twice.

 Famous Kalashnikov machine gun with a tape feed of cartridges / Manual on a small business. - M .: Military Publishing House, 1987, p. 351-394 /. The machine gun comprises a barrel, a receiver, a cartridge receiver, a bolt carrier, a cartridge extractor from a belt, a gas engine, a bolt, a return spring with a guide rod, a trigger, a bipod, or a machine tool. The supply of ammunition in the receiver is made of a metal tape laid in a box, mounted on an arm on the underside of the breech gun. Automation of the machine gun operates on the basis of using the energy of powder gases discharged from the bore to the gas engine with a drive rod to the bolt frame. Locking and unlocking the shutter is made by turning it around the longitudinal axis under the action of the bolt frame using combat projections and combat stops of the shutter and receiver. The trigger sear interacts with a platoon located on the underside of the slide frame. The trigger mechanism of the machine gun is used to hold the bolt frame on the combat platoon, lowering it from the combat platoon and putting it on the fuse. The drummer interacts with the slide frame and has no mainspring.

 The technical result of the claimed invention is to increase the combat effectiveness of the machine gun, reducing weight, improving manufacturability and reducing the cost of production.

 The specified technical result is achieved by the fact that the functioning of the machine gun automation is ensured by shuttle movements of the half-free shutter under the influence of powder gases directly through the piston rod of the gas engine and the slide pusher, using a kinematic pair with oblique engagement as a locking device, using a mass balancing device for moving parts weapons.

 The claimed invention differs from the known weapon in that it comprises a locking device with oblique engagement, a locking device with a gate drive directly from the gas engine rod, a belt feeding mechanism with a gate drive, a jumping cartridge bridge, a cartridge feed lever for the transfer line with the combined function of a battle whisper firing pin, firing pin with a mainspring located inside the bolt, mass balancing device for moving parts, balancer with combat platoon, flat return spring, with Uskova mechanism cooperating with cocking balancer reflective stem disposed within the valve.

 The reduced weight of the inventive machine gun is the result of the absence of the bolt carrier and structural elements that ensure its functioning.

 Improving the combat effectiveness of the claimed invention is a consequence of the use of mass balancing devices for moving parts. The use of this device can significantly increase the stability of the weapon during firing, to exclude the impact on the shooting of shock pulses of moving parts in extreme positions and reduce scattering. The high stability of the weapon, the absence of oscillations creates the possibility of effective use of an optical sight on it, which will significantly improve the accuracy of aiming, and will effectively hit small targets, such as loopholes, viewing slots of armored vehicles, etc. In addition, comfortable conditions are created for the shooter, which has great psychophysical significance.

 Lower production costs and higher manufacturability are associated with a certain decrease in the number of complex parts, and especially with the absence of a shutter frame with a large number of conjugate curved surfaces.

The essence of the invention is illustrated by drawings, which show:
Fig - Machine gun, the composition of the mechanisms.

 Fig.9 - Handle reloading.

 Figure 4 - Shutter with a locking mechanism.

 The locking device is a kinematic pair with oblique engagement. Inclined protrusions of the driving link are located in front of the shutter and are made together with it. The inclined slots of the driven link are located on the inner surface of the hub 3 / Fig. 8/, located between the annular stop 4 of the gun body and the breech section of the barrel. When the kinematic pair is engaged, the protrusions of one link enter the inclined grooves of the other link, while the drive link, which has freedom of only longitudinal movement, kind of screws on the driven link, which has freedom of only lateral movement. The position of full engagement is fixed by a stop 80, made in conjunction with the slide pusher 81, which, under the action of a spring 82 located on the stand 87 of the shutter, moving to the front extreme position, is located under the stop ledge 83 of the hub 3 and locks the shutter. To improve the adhesion and disengagement of the stop 80 and the locking protrusion 83, their contact surfaces are made with a bevel.

 The shutter automatic unlocking mechanism comprises a gas engine 6 and a cam follower 81 connected to its piston rod 7 with a stop 80 located on it. The cam follower 81 has a longitudinal protrusion 84 from the inside, which, when the hub 3 of the driven link rotates, enters the groove 85 of the locking protrusion 83 and holds the hub in the unlocked position for the duration of the shutter shuttle cycle.

 The manual reloading mechanism / Fig. 9/ contains a reloading handle 16 and a carriage 18 with a double-sided latch that fixes its front position. The carriage moves in the longitudinal groove of the gun body. The carriage has a rack for mounting the handle 16 and the leading protrusion 19, interacting with the driven protrusion 86 of the slide pusher when the bolt is retracted back.

 The cartridge belt feed mechanism is shown in FIGS. 3, 8. It is a conventional receiver for moving the belt, and has no features except for the feeder drive 24, the arrangement of which is shown in FIG. 8 dash-dotted lines. The feeder drive consists of a spring-loaded single-arm longitudinal lever 25 with an upper inclined edge located under the shutter, a pusher 26 located on the lower side of the front of the shutter. When the shutter moves back, the pusher 26, running onto the inclined face of the longitudinal arm 25, lowers its front part down and, acting on the lower arm 27 of the feeder 24, rotates the feeder counterclockwise / according to the drawing /, as a result of which the cartridge strip moves one link to the left .

 Cartridge bridge 28 is shown in figure 3, 4. It serves to support the bottom of the cartridge, sent by the bolt to the chamber. The cartridge bridge is a spring-loaded longitudinal panel that interacts with the bolt through the cam kinematic connection in such a way that when the bolt moves to the rear position, it is located in its place along the sending line and supports the front part of the cartridge being sent until the cartridge reaches the chamber, after of which the shutter, acting on the cam cut of the panel, shifts it down / under itself / and completely sends out the cartridge. The upper position of the cartridge bridge is shown in figure 3.

 The lever 29 for supplying cartridges, in addition to its regular function, also plays the role of a whispered combat platoon 30 of the striker 31 / Fig. 8/. When the shutter is moved to the forward position, the lever 29 catches the cocking 30, while the shutter continues to move forward, as a result of which the mainspring 32 is compressed. When the shutter reaches the front extreme position, the lever 29 is disengaged from the cocking by the wedge-shaped protrusion 33 of the shutter acting on trigger pin 34, located on the end of the lever 29. The hammer 31, as can be seen from the drawing / 4 /, is located inside the bolt, which has a longitudinal through groove 35 in the upper wall for moving the combat cock 30.

 The mass balancing device for the moving parts comprises a balancer 36, gear racks 37 of the shutter and 38 balancer and a gear wheel 39 interacting with it. The balancer is equipped with a machine gun platoon 40 that interacts with the trigger mechanism. The balancer is simultaneously a pusher of the return spring 41, consisting of a multi-package assembly of arcuate leaf springs.

 The trigger mechanism includes a trigger lever 42 with a spring 43, a trigger with a hook 44 that interacts with the trigger lever 42, and a fuse 45.

 The considered devices and mechanisms of the inventive machine gun interact as follows. During the initial loading, it is necessary for the reloading handle 16 to take the bolt back to failure, putting the balancer 36, and therefore the bolt on the cock, then return the reloading handle to its original position.

 1. When the reloading handles 16 are retracted, the leading protrusion 19 of the carriage 18, interacting with the driven protrusion 86 of the shutter pusher 81, brings the stop 80 out from under the locking protrusion 83, i.e. unlocks the hub 3, and therefore the shutter.

 2. The leading link, moving with the bolt back, with its inclined projections will rotate the driven link around the longitudinal axis and will disengage from it. The longitudinal protrusion 84 will enter into the groove 85 and the ban slave link in the extreme unlocking position.

 3. The extractor 46 with its hooks will remove the cartridge from the tape and move it back, while the cartridge will raise the lever 29 up; the cartridge, having reached the bottom of the sleeve to the feed ridge 47, under the influence of its bevel and spring-loaded lever 29 will lower down in front of the bolt, and the front of the cartridge - on the cartridge bridge that has moved upwards.

 4. When moving back the bolt with its lower pusher 26, acting on the upper inclined face of the longitudinal arm 25, it will shift its front part down and through the lower arm 27 of the feeder 24 will turn the feeder counterclockwise; feed finger 48, resting on the link of the tape, will move it to the left / according to the drawing / and install the next cartridge against the hooks of the extractor 46; the spring-loaded upper fingers 49 will jump over the next link and hold the tape in the receiver from shifting back.

 5. The backward movement of the shutter through the gear racks 37 and 38 and the gear wheel 39 will be transmitted to the balancer 36, which, compressing the return spring 41, will occupy the front extreme position; the trigger lever 42 under the action of its spring rises up and pops over the cocking position 40 of the balancer 36.

 The machine gun is loaded. To put on the fuse, it is necessary to move the bar 45 back under the trigger lever 42, as a result of which it will lose the ability to get out from under the cocking of the balancer.

 When starting on the trigger, the following actions will occur.

 1. The trigger with its hook 44 will release the trigger lever 42 from the engagement with the cocking 40 and the return spring 41 will throw the balancer 36 back, and the shutter 2 forward.

 2. The bolt, moving forward, will withdraw the cartridge from under the lever 29, the lever under the action of its spring will lower to the upper edge of the bolt and stand in the way of the cocking cock 30 of the striker 31, as a result of which its combat spring is compressed; however, with the bolt moving forward further when it reaches the front extreme position, the wedge-shaped protrusion 33, acting on the trigger pin 34, will raise the lever 29 up and out of engagement with the combat cock 30.

 3. In the forward position of the shutter, the protrusions of the leading link will enter the inclined grooves of the hub of the driven link and turn it counterclockwise, as a result of which the links will mesh; the emphasis 80 under the action of the spring 82 will move under the locking protrusion 83 and the ban on the driven link, as a result of which the driving link will be locked, therefore, the shutter; hammer striker 31 will break the capsules and a shot will occur.

4. The powder gases, passing through the gas hole in the barrel, will actuate the gas engine 6, which through the piston rod 7, acting on the shutter pusher 81, initially compresses the spring 82 and removes the stop 80 from under the locking protrusion 83, and then discards the shutter to the rear end position. In this case, the inclined protrusions of the driving link will rotate the hub 3 of the driven link clockwise and the longitudinal protrusion 84 will enter the groove 85 of the locking protrusion 83,
5. The shutter when moving back with the hook of the ejector 50/4 / will remove the sleeve from the chamber; the reflective rod 51, having encountered its crest 52 on the reflective protrusion / not shown / of the receiver, will strike the opposite end of the sleeve from the ejector’s aim and throw it out.

 Further, the considered automatic machine gun cycles will be repeated until the trigger is released.

 The invention - a machine gun with a balancer relates to the field of automatic weapons.

 Famous Kalashnikov machine gun with a store supply of cartridges / Manual on a small business. - M .: Military Publishing House, 1987, p. 235-279 /. The machine gun contains a barrel, receiver, bolt, bolt, return spring, trigger mechanism, sights, butt and bipod. Automation of the machine gun is based on the use of energy of powder gases withdrawn from the barrel to a gas engine with a drive rod to the bolt frame. Locking and unlocking the shutter is made by turning it around the longitudinal axis under the action of the bolt frame using the combat protrusions of the shutter and the combat stops of the receiver. The trigger mechanism is used to pull the trigger from a combat platoon or from a self-timer platoon, strike a striker, change the firing mode, prevent a shot when the bolt is not locked and to set the fuse.

 The technical result of the claimed invention is to increase the combat effectiveness of the machine gun, reducing weight, improving manufacturability and reducing the cost of production.

 The specified technical result is achieved by the fact that the functioning of the machine gun automatics is ensured by shuttle movements of the half-free shutter under the influence of powder gases on it through the gas engine directly through the piston rod and bolt pusher, using a three-link mechanism with two kinematic pairs with oblique engagement as a locking device balancing macc of moving parts of weapons and longitudinally multi-row magazine.

 The claimed invention differs from the known machine gun in that it comprises a locking device with oblique engagement, a locking device with a gas engine, a trigger mechanism with control of firing modes only through the trigger, a device for balancing the mass of moving parts, a flat return spring, a mechanism for sending cartridges from longitudinal - a multi-row store and a longitudinally multi-row store.

 Reducing the weight of the weapon is a consequence of the lack of a bolt carrier and structural elements that ensure its functioning.

 Improving the combat effectiveness of the claimed invention is a consequence of the use of mass balancing devices for moving parts. The use of this device can significantly increase the stability during firing, to exclude the impact on the shooting of shock pulses of moving parts in extreme positions and reduce scattering. The high stability of the weapon, the absence of oscillations creates the possibility of effective use of an optical sight on it, which will significantly improve the accuracy of aiming, and will effectively hit small targets, such as loopholes, viewing slots of armored vehicles, etc. In addition, comfortable conditions are created for the shooter, which has great psychophysical significance.

 Lower production costs and higher manufacturability are associated with a certain decrease in the number of complex parts, and especially with the absence of a shutter frame with a large number of conjugate curved surfaces.

The essence of the invention is illustrated by drawings, which show:
Figure 10 - Machine gun, the composition of the mechanisms.

 6 - The mechanism of fire control.

 The locking device is a three-link mechanism with two kinematic pairs with oblique engagement, containing two counter leading links made one together with the shutter, the other with the breech of the barrel, and the follower link located between them. The links contain protrusions and elongated grooves inclined relative to the longitudinal axis. The driven link is made in the form of a hub 3 with bilateral engagement, the protrusions and grooves of which are made on the inner surface. The engagement of all three links occurs when the protrusions of one link enter the inclined grooves of the other link when the shutter moves to the front end position. When the links come closer, the hub of the driven link is sort of screwed onto the leading links of the shutter and barrel. The position of full engagement is fixed by an emphasis 80, made in conjunction with the slide pusher 81, which, under the action of the spring 82, moving to the front end position, is located under the locking protrusion 83 of the driven link of the locking device. To improve the adhesion and disengagement of the stop 80 and the locking protrusion 83, their contact surfaces are made with a bevel. When fixing the position of full engagement emphasis 80, the shutter locks in the extreme forward position.

 The automatic gate unlocking mechanism comprises a gas engine 6 and a cam follower 81 connected to its piston rod with an abutment 80 located on it. The cam follower 81 has a longitudinal protrusion 84 on its inside, which, when the hub 3 of the driven link rotates, enters the groove 85 of the locking protrusion 83 and holds the hub in the extreme unlocking position for the duration of the shuttle shutter cycle.

 The manual reloading mechanism / Fig. 9./ contains a reloading handle 16 and a carriage 18 with a double-sided latch that fixes its forward position. The carriage moves in the longitudinal groove of the weapon body. The carriage has a rack for mounting the handle 16 and the leading protrusion 19, interacting with the driven protrusion 86 of the slide pusher when the bolt is retracted back.

 The trigger mechanism / 6, 10 / is designed to lower the drummer from a combat platoon, control modes of single and continuous shooting. A feature of the trigger mechanism is the way to control firing modes through the trigger. When the trigger is incompletely pressed, a single firing mode is provided; when fully pressed, the continuous firing mode is provided. The trigger mechanism contains a firing pin with a mainspring located inside the bolt, a cocking platoon 30 of the striker, the crest of which moves in the longitudinal through groove of the upper wall of the bolt, a trigger 54 with a spring, a firing limiter 55, a trigger chain 56, consisting of two levers, trigger rod 57, the end of which is connected to the firing control panel 58, moving in longitudinal guides above the shutter. On the firing control panel, there is a control mechanism for the leading sear 59 and the striker 60 catcher. The lead sear and the platoon catcher are made in the form of two shoulders levers located on the stand 61. Their right / according to the drawing / shoulders contain lateral protrusions 62 and 63 interacting with the firing control panel 58. The lead sear interacts with the copy path formed by cutout 64 and the protrusion 65 of the firing control panel, during its longitudinal movement, and the catcher 60 combat cock interacts with the trigger lever 66, mounted on an axis on the firing control panel. The trigger lever 66 on the right / according to the drawing / end part has a roller 67 interacting when moving to the left with the protrusion 68 of the shutter, and when moving to the right with a fixed protrusion 69 of the weapon body.

 The mass balancing device of the moving parts comprises a balancer 36, gear racks 37 and 38 located on the shutter and balancer, and a gear wheel 39 interacting with them.

 A flat return spring 41 is located above the bolt and barrel and contains a multi-pack assembly of arcuate leaf springs and a stop-slider connected to the balancer, through which the balancer compresses the return spring when fired.

 The suction mechanism comprises three spring-loaded longitudinal feeders 71 located on the lower side of the shutter, and a guide cartridge bridge 72 located in front of the front section of the longitudinally-row magazine 73.

 The reflective mechanism of the machine gun consists of a longitudinal rod located inside the bolt in such a way that its front end part interacts with the edge of the sleeve opposite the ejector engagement, and its crest 52, which moves in the longitudinal through groove of the bolt and interacts with the reflective protrusion (not shown) / receiver.

 The fuse is located above the trigger. It is a single-arm lever 74 with an angular hook on the free end and has two positions. In the lower position shown in figure 10, the lever prevents the trigger 54 from moving, in the upper position of the lever, its hook is disengaged from the trigger.

 The sighting device of the machine gun consists of two racks connected by a jumper. There is a front sight on the front desk, and a sight on the rear desk. The chapel has a moving rear sight with a slot for aiming and a mechanism for entering corrections in distance and direction. Corrections are entered using two handwheels 75 located on the side of the rear pillar. On the rear side of the rack facing the arrow, there is a correction scale. Racks with a jumper serve simultaneously as a mounting point for an optical sight.

 The machine gun is equipped with a counter 76 remaining cartridges in the store. The drive rod 77 of the counter interacts with the hub 3.

 Longitudinally multi-row magazine 73 contains interacting cartridge sections, equipped with devices for blocking the supply of cartridges in the upper horizontal row of the sections that are next in order in the presence of cartridges in the presence of cartridges in the previous section.

 The considered devices and mechanisms of the inventive machine gun interact as follows. During the initial charging, it is necessary for the reloading handle 16 to take the shutter back to failure and release it.

 1. Under the influence of the reloading handle, the pusher 81 through the carriage 18 and the contact kinematic connection: the leading protrusion 19 - the driven protrusion 86, moving backward, will bring the stop 80 out from under the locking protrusion 83 of the hub 3. The shutter will unlock.

 2. The pusher 81 will compress the spring 82 and, acting on the protrusion 20, will move the bolt to the rear extreme position, while the hub 3 will rotate around its longitudinal axis and the driven and driving links will disengage; the longitudinal protrusion 84 of the pusher 81 will enter the groove 85 of the locking protrusion 83 of the hub and prohibiting it in the extreme position for the duration of the cyclic shutter stroke.

 3. Longitudinal feeders 71 pop over the trailing edges of the cartridges in all sections of the longitudinally multi-row magazine; the platoon 30 will move with the bolt to the rear extreme position and will drop behind the leading sear 59.

 4. The balancer 36 under the action of the gear racks 37 and 38 and the gear 39 will move to the front position and compress the return spring 41.

 5. During the reverse stroke, the shutter under the action of a return spring will send the upper cartridge of the front section to the chamber, move the cartridges from the middle section to the front, from the rear section to the middle, and the cartridge of the next second row will take the place of the moved cartridge of the rear section.

 6. The leading sear 59 will stop the cocking unit 30, as a result of which, when the bolt moves further forward, the hammer spring will compress.

 7. The protrusions of the links will go into the conjugate inclined grooves and the hub 3 will be screwed onto the leading links of the bolt and barrel until fully engaged; the emphasis 80 of the pusher 81 under the action of the spring 82 will move under the locking protrusion 83 and the prohibition of the hub 3, and therefore the shutter.

 The machine gun is ready to fire.

 Single shooting is performed when the trigger is incompletely pressed. As an indicator of incomplete depression, a spring limiter of the firing mode 55 is used, which at the end of incomplete depression of the trigger provides additional resistance. To ensure the absolute reliability of a single shot, the machine gun is equipped with a firing limit pedal located on the left side of the handle. When you press the pedal with the thumb of your right hand without changing the grip of the weapon, the spring limiter of the firing mode 55 with the pusher 78 connected with the pedal is fully extended and prevents the trigger from being fully pressed. When the trigger is incompletely pressed, the interaction of the devices and mechanisms of the machine gun will be as follows.

 1. The firing control panel 58 will shift to the left / according to the drawing /, the roller 67 will escape from the stationary protrusion 69 and the trigger lever 66 will turn clockwise, but the position of the catcher 60 of the combat platoon 30 will not change, since its left end part is located on top of the combat platoon; as the firing control panel is moved further, the host whisper 59, acting on its right shoulder with the protrusion 65 of the copy path, will turn clockwise and disengage from the cocking, resulting in a shot.

 2. When fired, the powder gases entering the gas engine 6 through the gas hole in the barrel, throw the bolt back through its piston and rod, acting on the pusher 81, and all actions will occur in the same way as when releasing the bolt through the reload handle, except that the firing squad 30 of the striker will be intercepted not by the leading sear 59, but by the catcher 60 of the combat platoon 30 / since the trigger is pressed /.

 3. When the bolt moves backward, the ridge 52 of the reflective rod, upon encountering the reflective protrusion of the receiver / is not shown /, will strike at the opposite edge of the sleeve bottom and eject it outward.

 In order to fire the next shot, release the trigger and press it again. When the trigger is released, the firing control panel 58 will shift to the right / according to the drawing /, the side protrusion 62 of the leading sear will move from the protrusion 65 of the copy path to the notch 64, as a result of which the leading sear will turn counterclockwise and its end part will stand against the combat platoon; the roller 67 of the trigger lever 66, having run onto the stationary protrusion 69, will turn the lever counterclockwise and disengage the catcher 60 from the engagement cock, which, having moved slightly forward, will engage with the lead sear.

 When the trigger is fully pressed, the firing control panel 58 will move even further to the left extreme position. The presenter whispered 59 under the action of the protrusion 65 of the copy path after the first shot will remain in the raised position, and firing control will move to the movable protrusion 68 of the shutter. When the bolt reaches the front extreme position, the protrusion 68 will move under the roller 67, which will cause the trigger lever 66 to turn counterclockwise and disengage the catcher 60 from the engagement cock 30, as a result of which a shot will occur. This kinematic pattern will be repeated and will provide continuous firing until the trigger is released.

 The machine gun is designed to use a longitudinally multi-row magazine for 60-70 rounds. However, it can also be used standard box-shaped for 40 rounds and drum for 75 rounds stores. For this purpose, an adapter 79 / Fig. 10/ is provided in the machine gun, comprising a fastening mechanism for single-row magazines moving along longitudinal guides along the butt of the magazine. When using a longitudinally multi-row magazine, the adapter is shifted to a niche located in the end of the butt. When using single-row box or drum magazines, the adapter moves, for example, to the zone of the second section of the longitudinally multi-row magazine and is fixed in this position by a latch. In the case of single-row magazines, the first cartridge is sent to the chamber after twisting the shutter twice.

 The invention - a method of locking the shutter relates to the field of automation systems of small arms.

 Analogues of the claimed method of locking the shutter is not found.

 The technical result of the claimed invention is to reduce the weight of weapons, improve manufacturability and reduce production costs, the possibility of using various systems of long-barreled and short-barreled weapons.

 The specified technical result is achieved by the fact that the locking of the shutter is based on a kinematic pair with oblique engagement containing the leading and driven links. The lead, made in conjunction with the shutter and the slave, made with the possibility of only lateral movement of the links are provided with protrusions and grooves inclined relative to the longitudinal axis of the shutter. The protrusions of one link enter the grooves of the other link while moving the links of the lead in the longitudinal, driven in the transverse directions. In the initial period of the shot, the counteraction mechanism, for example, in the form of a movable stop, blocks the reverse displacement of the driven unit under the influence of powder gases on it through the shutter and protrusions of the driving link, which locks the shutter in the forward extreme position. At a given moment, the countermeasure mechanism unlocks the driven link, as a result of which the driving link, moving back together with the shutter, with its protrusions interacting with the inclined grooves of the driven link, moves it in the opposite transverse direction, disengages from it and the shutter is thrown back, and for the duration of the shuttle shutter cycle, the driven link will remain in this extreme position under the action of the position lock.
