COMBINED RECOIL ABSORBER Russian patent published in 2012 - IPC F41A25/02 F41A25/16 

FIELD: weapons and ammunition.

SUBSTANCE: combined recoil absorber comprises an outer and a working cylinder, a piston, a stem, a stuffing box. In a hollow stem on a rod rigidly joined to the body there is a piston installed, which develops an underpressure area when moving (a pneumatic part of the device), at the same time the hydraulic cavity of the inner cylinder via valves of recoil and counterrecoil braking is connected to cavities of the outer cylinder (a hydraulic-pneumatic part of the device). A spring is fixed on the hollow stem, which with one end rests against the piston, and with the other one - against the cylinder body, providing for recoil, counterrecoil and retention of recoiling parts in all corners of barrel elevation.

EFFECT: higher efficiency and reliability of a device due to recoil and counterrecoil, reduced length of recoil.
