The following is a detailed description of the design and operation of the claimed automatic firearms with reference to the drawings.

Automatic firearms made with a movable barrel 2 and a chamber 9, placed in the receiver 5 (Fig. 1). The mobility of the barrel 2 is provided by an electromagnetic pulse generator 6, which is powered by an electric current accumulator 37 and a gas engine 8. The gas engine 8 is designed to return the movable barrel 2 to its original position, contains a gas piston 43, which is mounted on the movable barrel 2 and reliably fixed by means of a threaded connection using a muzzle device 1 (Fig. 1), (Fig. 2). The protective casing 4 of the barrel is designed to isolate the hands of the shooter from the movable barrel 2 and is fixed relative to the receiver 5 by means of a groove. The gas piston 43 moves due to powder gases in the gas tube 44, which, in turn, is secured by welding to the protective casing of the barrel 4 (Fig. 2).

The locking mechanism is formed by an electromagnetic pulse generator 6, a cartridge support with a support heel 18, which rests on the support sleeve 19, which has a protrusion under the damper safety spring 21 on compression, which supports the support sleeve 19 in the receiver tip 23, which, in its the turn is fixed in the receiver 5 with locks 22 of the receiver (Fig. 2). The connection of the support heel 18 and the support sleeve 19 into a single part is carried out using the connecting finger 17 (Fig. 2).

The trigger mechanism includes a stationary firing pin 20, which passes with a gap through the support sleeve 19 and the support heel 18 of the cartridge, is securely fixed to the body of the receiver tip 23 from the back side, and the trigger mechanism includes an electromagnetic pulse generator 6, a safety damper a spring 21, a trigger 39, which is installed in the response grooves of the holding element 7. The electromagnetic pulse generator 6 is mounted on the outside of the receiver 5, its front part abuts against the side the receiver, from the back it is locked by the housing of the battery 37 electric current, which, in turn, is fixed by locks 22 of the receiver. The trigger 39 contains a fuse 40 from an accidental shot and the contacts 38 of the trigger (Fig. 2).

The power supply mechanism for automatic firearms with cartridges 29 has a magazine 30 base, its lower part is closed by a magazine cover 35, on which an electric motor 31 is fixed in special grooves, which rotates in the absence of a cartridge 29 in the region where the cartridge position sensor 42 is installed with a certain gear frequency of 32 screw shafts, gears are connected by a toothed belt 33. The rotational movement from the electric motor 31 is transmitted to the movable shelf 36 by means of screw shafts 34. The rotation speed of the shaft of the electric motor 31 is adjustable Xia rheostat 41 of the motor shop. The magazine 30 is fastened on both sides by the cylinder locks 28 of the magazine, which are installed in the receiver 5. The opening of the cylinder locks 28 of the magazine is carried out by the lever mechanism 27 for controlling the magazine locks, which is installed in the corresponding protrusion of the receiver 5 (Fig. 2), (Fig. 3 )

The sighting device 3, consists of two elements (sighting strip and front sight), which are mounted on the protective casing 4 of the barrel and the generator 6 of electromagnetic pulses by means of screws (Fig. 1), (Fig. 2).

Removing the spent sleeve occurs after a shot when moving the movable barrel 2 to its original position. Removing the sleeve from the chamber 9, is due to the hooks 14 holding the sleeve, and removing from the receiver 5 - using the protrusion-extractor 25 (Fig. 2), (Fig. 3). Hooks 14 retention sleeve installed in the grooves of the supporting heel 18 of the cartridge, where there are also springs 16 of the hooks of retention (figure 3). The fastening of the hooks 14 holding the sleeve in the supporting heel 18 of the cartridge is due to the support fingers 15 of the hooks holding the sleeve (Fig. 3). The protrusion-extractor 25 is an element of the movable barrel 2 (Fig. 2), (Fig. 3).

The control mechanism of the generator 6 of electromagnetic pulses, has a slider 10, which is installed on the side of the receiver 5, in a special protrusion, which is closed from external influences by the cover 26 of the slider 10 (Fig. 3). The slider 10 has two locking positions, depending on which the contacts of the barrel position sensor 13, which is also located under the cover of the slider 26, are closed or open. The locking of the slider 10, occurs using the clamp 11 of the slider, which acts on the spring 12 of the clamp of the slider (Fig. 3). The translation of the slider 10, from one position of fixation to another occurs due to the protrusion 24 to determine the position of the movable barrel, which is an element of the movable barrel 2 (Fig. 3).

The proposed firearm works as follows.

To bring automatic firearms into combat condition, the shooter first equips the magazine with cartridges, then fastens it to the weapon. Next, takes the weapon in a convenient position for shooting and brings the sighting device 3 in accordance with the shooting conditions. During firing, the weapon is held by the holding elements 7. To remove the weapon from the fuse 40 from an accidental shot, you must press the trigger 39. The removal from the fuse occurs automatically due to the fact that in the trigger 39, which is made of dielectric material, there are two unbound between themselves metal rods, which from the back, when you press the trigger 39, each connect with its contact 38 of the trigger, and the connection of the rods themselves occurs in front of the trigger th hook 39 by abutting the metal rods fuse contact washer 40, on which the shape of the trigger 39 may affect only the index finger or the closest to the subject of his anatomy. Next, the electric current from the electric current accumulator 37 is supplied to the cartridge position sensor 42, if the cartridge 29 is in the desired position, the electric motor 31 in the magazine 30, supplying the cartridges 29 is turned off, then the electric current is supplied to the barrel position sensor 13. If the movable barrel 2 is in the initial position, then the contacts of the barrel position sensor 13 are in the closed position, as a result of which electric current is supplied to the input of the electromagnetic pulse generator 6, which drives the movable barrel 2 backward, while the cartridge 29, which is located, is captured at the right angle to the movable barrel 2, leading it from the magazine 30 to the chamber 9, while resting the cartridge 29 in the support heel 18 of the cartridge, after one fifth of the distance traveled by the mobile barrel 2, the holding hooks are released tions of the sleeve 14, which is actuated by springs 16 and retaining hooks grip chuck 29 for a special groove. Next, the protrusion 24 to determine the position of the movable barrel is driven by a slider 10, which is translated into the second position and is fixed by the latch 11 of the slider. The slider 10, in turn, opens the contacts in the sensor 13 of the position of the barrel, and the electric current ceases to flow to the input of the electromagnetic pulse generator 6, but the movable barrel 2 continues to move by inertia. The cartridge 29 completely enters the chamber 9 and transfers the action of the movable barrel 2 to the support heel 18 of the cartridge, which in turn acts on the support sleeve 19. The sleeve 19 abuts against the damper safety spring 21, which is compressed by the inertia of the movable barrel 2 hammer 20, pricks the capsule in the cartridge 29, as a result of which a shot occurs. Gunpowder gases from the movable barrel 2 enter the gas tube 44 and displace the gas piston 43, which is rigidly connected to the movable barrel 2 and drives it forward to its original position. In this case, the sleeve of the cartridge 29 is held by the hooks 14 to hold the sleeve, as a result, it is removed from the chamber 9. Through the required distance traveled by the movable barrel 2, the protrusion 24 to determine the position of the movable barrel affects the slider 10, and the slider goes into the first position. When this happens, the contacts are closed in the sensor 13 of the position of the barrel, and electric current begins to flow to the input of the generator 6 of electromagnetic pulses, as a result of which the movable barrel 2 is partially braked, then at some point the hooks 14 of the sleeve hold open due to the entry of their special protrusions into the this grooves on the back of the movable barrel 2 and the sleeve of the cartridge 29 is removed from the receiver 5 by exposing it to the protrusion-extractor 25. Next, the movable barrel 2 rises to its original position , begins the flow of electric current into the electric motor 31 of the store 30 and the next cartridge 29 in turn, rises to its original position.

The cycle is repeated until the trigger 39 is held in the shot position, or until the cartridges 29 are consumed, their absence in the magazine 30.
