Abstract

In a rock drill, the feed force is transmitted from the housing 11 of the rock drill to the drill stem or drill stem adapter 14 via damping piston 17. The damping piston 17 rebounces by the reflected compressive shock waves and the rebounce is sensed and used to control a control pin 48 which adjusts the stroke length of the hammer piston 13 so that the reflected shock wave energy is minimized.
