Abstract
A recoil-actuated gun scavenger for a gun having a bore, a breech, a recoiling mass, and a non-recoiling mass. The scavenger may include a pneumatic cylinder and a piston translatable therein. A rod may be fixed to the piston. The cylinder and rod may be fixed to respective recoiling and non-recoiling masses, or vice versa. The cylinder may include intake and exhaust ports with check valves, on both sides of the piston. The exhaust ports may communicate with an accumulator. The accumulator may discharge compressed air to jets located at the open breech end of the gun.

A recoil-actuated gun scavenger for a gun having a bore, a breech, a recoiling mass, and a non-recoiling mass, the scavenger comprising:
- a pneumatic cylinder having a piston disposed therein, the cylinder and the piston being translatable with respect to each other, the cylinder being fixed to one of the recoiling mass and the non-recoiling mass;
- a rod having one end fixed to the piston and another end fixed to another of the recoiling mass and the non-recoiling mass;
- a pair of air intake ports in the cylinder, the pair of intake ports being disposed on opposite sides of the piston, each intake port including a one-way valve;
- a pair of air exhaust ports in the cylinder, the pair of exhaust ports being disposed on opposite sides of the piston, each exhaust port including a one-way valve;
- an air accumulator in fluid communication with the pair of exhaust ports;
- a discharge valve in fluid communication with the air accumulator, the discharge valve having an open position and a closed position;
- and
- at least one jet disposed at a breech end of the bore of the gun, the at least one jet being in fluid communication with the discharge valve;
- wherein air compressed into the accumulator by the piston is discharged from the at least one jet into the breech end of the bore when the breech of the gun opens.
