METHOD FOR REDUCING RECOIL FORCE OF FIREARMS AND GUN WITH FOLDING BARREL CHAMBER FOR IMPLEMENTATION THEREOF (EMBODIMENTS) Russian patent published in 2020 - IPC F41A1/08 

FIELD: weapons.

SUBSTANCE: method for reducing the recoil force of firearms consists in the fact that removal of shot cartridge by pressure of powder gases is carried out at the deflected cartridge simultaneously with projectile projection from the barrel. Shell extraction and flapping is performed by means of high pressure of powder gases acting on the cartridge case and slide chamber bottom. When the cartridge chamber leaves the wedge the cartridge opening channel is opened. Gun with swinging cartridge chamber for implementation of method comprises: loaded barrel; barrel receiver, in which the chamber with rocking shafts is installed with possibility of tilting, radial sliding element, gate, sliding gate plating of gate wedge lifting, return spring. Barrel chamber is equipped with grooves of Revelli. Cartridge feed mechanism selector makes it possible to select shell type during firing from two feeding channels. Punching mechanism produces direct inertial throwing of cartridge from link. Drive of energy-intensive mechanisms is carried out by two spring accumulators of mechanical energy. Gun also comprises system of electric or mechanical ignition of cartridge fuse, hydraulic brake, cooling system, electric pyrotechnic mechanisms for recharging and ignition of axial cartridge, collector, balancing mechanism, gas-dynamic stabilization system in form of nozzle and/or muzzle devices.

EFFECT: technical result is reducing recoil force, increasing automatic firing rate, reducing gun weight, enabling gun to be mounted on light mobile platforms, increased safety, increased reliability, increased combat efficiency of gun, simplified design, possibility of automatic firing of non-useless and/or telescopic cartridges.
