ANTI-RECOIL DEVICE WITH BRAKE, BRAKE COMPENSATOR AND RECUPERATOR

摘要

The invention concerns anti-recoil device for cannons and mortars, comprising a brake with a main cavity (1) containing a main piston (2) bored with holes (20). The brake small chamber (11) is connected by an orifice (C) to an annex chamber (61) closed by a sealed piston (60). The main cavity and the auxiliary chamber are filled with a liquid (4) while a pressurised gas (6), at the other side of the sealed piston relative to the auxiliary chamber, tends to push back the auxiliary piston. A valve (21) partly closes the main piston bores, when the firing position is restored, so as to brake said return. The invention is applicable to the firing tubes of cannons and mortars.
