Abstract

Improvements in hydraulic percussion apparatus with a working piston that moves inside a working cylinder and a regulating element that moves inside a regulating cylinder and that has at least one regulating surface on which the pressure acts of a regulation line connected to the working cylinder, with a pressure accumulator attached to the pressure line and with a pumping device that transports liquid under pressure in the pressure line, characterized in that to produce blows, the force of which percussion is constant regardless of the flow rate of the pumping device, a device is provided that after or in the course of raising the working piston allows a switching of the regulation element to that position that corresponds to the percussive movement of the working piston only when the pressure and volume inside the pressure accumulator have exceeded u n limit value.
