Description

The invention relates to artillery and is intended for any guns, especially portable ones.

Known sliding and rolling devices in artillery, see, for example, US Pat. No. RU 2363908. The disadvantage of any of the existing sliding devices (hereinafter referred to as the “recoil device”) is that the energy of the recoil is dissipated, turning into harmful heat, without doing useful work.

At the same time, the guns overheat during intense shooting, which leads to a decrease in firing accuracy and to increased barrel wear.

The objective and technical result of the invention is to reduce the heating of the recoil device, as well as the beneficial use of recoil energy to purge the barrel and, possibly, to drive the aiming and reloading mechanisms of the gun.

The essence of the invention is the accumulation of air pressure and its use for these purposes.

To do this, this recoil device, in addition to the recoil energy conventional for barrel artillery and dissipator, for example a hydraulic cylinder, has a pneumatic cylinder connected to the barrel or with the movable part of the recoil device, or has a bellows or a membrane box, or several mechanically connected bellows and membrane boxes having an exhaust valve and an intake valve and air supply to the receiver, and several membrane boxes or bellows are connected in parallel with the receiver.

Several membrane boxes or bellows are connected mechanically in series because the stroke of the bellows or membrane box is small compared to the rollback length.

Since the atmosphere around the gun can be dusty, the air is sucked into the pneumatic cylinder, bellows or membrane box (hereinafter “pneumatic cylinder”) through the air filter.

The resulting compressed air can be spent on actuators of the aiming and reloading mechanisms, and on purging the barrel from hot powder gases. It’s better to use hydraulics for the drive, but this barrel is especially suitable for blowing the barrel.

For this, the recoil device has a protrusion on the barrel or on the movable part of the recoil device, which briefly interacts with a spring-loaded air supply valve from the receiver to the nozzle device / devices directed into the open shutter of the gun barrel.

To increase the purge efficiency, the nozzle device may have an ejector supplying additional air to the barrel.

In the case of using compressed air only to purge the barrel, the receiver can have a minimum size (approximately 1/3 of the volume of the pneumatic cylinder).

The invention does not need graphic materials.

The recoil device works as follows: during the rollback, the pneumatic cylinder contracts and supplies air through the exhaust valve to the receiver. When rolling, the protrusion on the barrel touches a spring-loaded valve, and a portion of air is blown into the barrel through an ejector device, blowing the barrel from hot powder gases.

In large-caliber guns, compressed air can also be used for a pneumatic drive supplying a projectile to the barrel.
