ABSTRACT:
To facilitate the return of a percussion tool by the action of the striking mass, namely, a double-acting piston, without damage to the machine body, the tool is held by a casing attached to the body and the tool. The latter piston defines a chamber with a confronting face of the casing, the chamber being supplied with a liquid under pressure through a check valve. The chamber is connected to a reservoir by a pressure-relief valve.
