RU2231730C1 - Multifunctional pneumatic gun - Google Patents

Abstract

FIELD: pneumatic weapon shooting not only by pneumatic bullets, but also by low-power cartridges of various purpose: signal, gas-light, etc, using an impact primer for ignition of the powder charge.

SUBSTANCE: the weapon has a housing, barrel with a bullet located in the housing, gas chamber with a valve for feeding of a portion of gas, mechanism for opening the valve for feeding of a portion of gas. Installed in the front section of the weapon housing coaxially with the bore before the muzzle end is a guide cavity in the form of an open cartridge chamber for an alternate feed of low-power cartridges of various purpose to it with the primer to the muzzle end.

EFFECT: enhanced functional potentialities of the pneumatic weapon.

Description

The invention relates to pneumatic weapons firing bullets having a spherical or conical warhead, in particular ball bullets, and can be used in pistols, revolvers, shotguns, etc.

Known pneumatic pistols MP654 K (1), "ANICS" (2) and others containing a body, a barrel with a bullet, a gas chamber with a gas portion valve, cocking and descent mechanism.

The disadvantage of these pistols is the inability to use other ammunition for shooting from them, except for pneumatic bullets.

An object of the invention is the creation of a new design of airguns, allowing you to shoot from it not only with pneumatic bullets, but also with various types of low-pulse cartridges with an impact-type igniter capsule, triggered by an impact of an air bullet flying out of the barrel, in particular a ball bullet.

This problem is solved in that in a pneumatic weapon containing a housing placed in the barrel for the placement of a bullet, a gas chamber with a gas portion valve, a mechanism for opening the gas portion valve, a guide rail is mounted coaxially with the barrel bore in front of its barrel muzzle a cavity in the form of an open chamber with the possibility of alternately feeding a capsule into the barrel muzzle section of low-pulse cartridges for various purposes.

This design of airguns allows you to fire from it with various low-pulse cartridges: signal, gas, liquid, light, noise, that is, those cartridges that have a slight recoil momentum and which, when fired, serves as a chamber.

Thus, pneumatic weapons are transformed into signal, gas, barrelless self-defense weapons, etc. depending on the type of ammunition used.

The destruction of the igniter capsule and the removal of the spent sleeve or axial cartridge is carried out due to the energy of the pneumatic bullet flying out of the barrel.

The guide cavity can be mounted directly on the barrel in the form of a muzzle attachment.

The supply of cartridges in the guide cavity can be done either manually with a single-shot version of the weapon, or automatically - from magazines of various designs - with a multi-charge version of the weapon.

The guide cavity can also be made in the form of a chamber of a revolving drum with the possibility of alternately combining the axis of each chamber with the axis of the barrel channel.

On the guide cavity can be installed a mechanism that prevents the loss of cartridges from it, and a mechanism that regulates the range of the ejection of cartridges.

A reflector (or trap) of a pneumatic bullet can be provided on the body of the weapon, preventing it from ricocheting back into the barrel.

Diagram of a multifunctional airgun with a magazine depicted:

figure 1 - initial position;

figure 2 - the time of departure of the pneumatic bullet along with the cartridge from the guide cavity.

The weapon comprises a housing 1, a barrel 2 with a bullet 3 located in the housing 1, a gas chamber 4 with a valve 5, a drummer 6 of a gas portion valve opening mechanism (not shown), a magazine 7 with a spring-loaded feeder 8, a guiding cavity 9 with a cartridge 10 located on the line of fire.

The proposed weapon works as follows.

The drummer 6 of the opening mechanism of the gas supply valve strikes the stem of valve 5, while valve 5 opens briefly, releasing a portion of gas that exerts pressure on the bullet 3 located in the barrel 2 and accelerates it. The first pneumatic shot occurs.

Next, the bullet 3 when flying out of the bore of the barrel 2, in turn, hits the capsule of the cartridge 10, igniting it, and simultaneously knocks the cartridge 10 out of the guide cavity 9 forward, in the direction of its movement. There is a shot from the cartridge 10 and the simultaneous release of the spent sleeve.
