摘要
Damping device for a percussion device of a rock drilling machine (1) having a striking direction (R), including a damping piston (8) for action in an axial direction against a tool to be driven by the percussion device, wherein the damping piston (8) exhibits a piston portion (6), which is received in a damping chamber (7) whereto is connected a damping flow circuit including a supply conduit (14), and wherein an outlet conduit (15) is connected to the damping chamber. A damping flow regulator (10) being controllable in respect of damping flow in the damping flow circuit is arranged in said supply conduit (14), and a control means (11) is arranged to emit control signals to the damping flow regulator (10) for regulating said damping flow. The invention also concerns a percussion device, a rock drilling machine and a method.
