摘要： The invention relates to a percussion device having a frame, a tool mounted movable in its longitudinal direction, the percussion device containing a work chamber having a movably mounted transmission piston to compress the tool so that a longitudinal stress pulse is generated to the tool, inlet and outlet channels for conducting the pressure fluid to the percussion device and away from it and a control valve that alternately directs the pressure fluid from the inlet channel to the work chamber to act on the transmission piston and, correspondingly, discharges the pressure fluid from the percussion device. The percussion device and trans-mission piston have channels that connect the pressure fluid that acted on the transmission piston to flow during the return movement of the transmission piston through the control valve and transmission piston to the pressure fluid outlet channel and cut off the flow when the transmission piston has returned to its initial position.

摘要： The invention concerns a rock drill (2) for activating a rotatable and reciprocable drill steel assembly (FIG. 1 ). A reversible motor (50) is coupled to a striking bar (3) for rotating the drill steel. The striking bar is struck by a percussion piston (10). A rotary fluid valve (15) is operating the piston. A disconnectable coupling (37,38,43) in normal operation couples both the valve (15) and the striking bar (3) with the motor (50). In special modes the motor operates only the percussion piston, e.g. for retracting a drill rod, or only rotates the striking bar (3), e.g. for connecting and disconnecting drill rods.
