Description

The invention relates to the field of weapons technology, in particular, to the self-loading pistols and can be used for combat use in any kind of troops.

A known design of a self-loading pistol according to the patent of the Russian Federation No. 2088879, IPC F41C 3/00, publ. 08/27/97, containing a movable barrel, frame, free gate, return spring and firing mechanism. The disadvantage of this gun is a large weight with ammunition, the inertia of the firing mechanism when fired.

Of the known, the closest in technical essence is a pistol containing a frame, a barrel, a free bolt with a trigger mechanism and a spring-loaded larva, a magazine and a return spring. The barrel is mounted in a frame with the possibility of longitudinal movement together with the shutter and bolt larva so that their impact in the rearmost position on the frame occurs sequentially. The shutter has a protrusion for consistent interaction with the barrel and frame. The force of the spring of the trunk is significantly greater than the effort of the return spring (Patent RU No. 2453787 IPC F41C 3/00, F41A 3/56 publ. 06/20/2012).

The disadvantages of the pistol is a relatively high mass, the trigger release with a drummer and cartridge case that does not provide a smooth descent, reduces the accuracy of shooting.

The present invention is aimed at reducing the mass characteristics of the gun, ensuring smooth descent and increasing the accuracy of shooting.

This is achieved by the fact that the device proposes the use of a cartridgeless cartridge and electrostart using a piezoelectric generator. The charge is ignited by an electric igniter connected to a circuit with high-voltage capacitors and a microcontact, triggered by a trigger.

The use of caseless cartridges of unitary loading in the store allows you to consistently send a bullet with a charge into the barrel when the bolt moves forward.

The use of electric ignition provides stable charge ignition without capsule.

FIG. 1 shows a general view of the device from the side; FIG. 2 - view from the muzzle. Electrically-driven pistol consists of a barrel 1, a frame of the bolt 18, a recoil spring 2, a bolt 4, a pistol grip 12, a trigger 16, a magazine 14, in which unitless charging cartridges 5 are located, preloaded by a tray through the supply spring 15, the magazine is located a power supply unit consisting of a package of piezoelectric sensors 8 divided by cup springs, which are affected by a loading spring 6 and connected to a circuit with a converter 10, a high-voltage unit 11, a switch 17, a package of high-voltage capacitors 13, are connected with electric spark device 3.

The device works as follows. To produce the first shot, the bolt 4 is manually retracted, freeing the movement of the cartridge from the magazine to the discharging line. In this case, the return spring 2 and the loading spring 6 are compressed. When the shutter moves under the action of the compressed spring 2, the cartridge is sent to the chamber, which interacts with the shell of the sleeve with the electric-spark device 3 and provides direct contact with the powder charge. When a loading spring 6 is pressed onto the piezoelectric sensors 8, an electric current arises, which enters the converter 10 through conductors, then into the high-voltage unit 11 and into the package of high-voltage capacitors 13. The capacitors are charged. When you press the trigger closes the contacts of the switch 17, while the voltage is applied to the electric-spark device 3, there is a spark discharge, which ignites the charge of the sleeveless cartridge of the unitary loading 5.

The present invention uses bezgilzovy cartridge, therefore, on the spot firing does not remain fired shells, reduced curb weight of the gun, fatigue during long firing, increases the accuracy of fire.

The use of caseless cartridges saves non-ferrous metals in the mass production of cartridges.
