Abstract:
According to one aspect of the invention hydraulic pressure pulses are created in a rock drill machine utilizing a rod (7, 7a, 7b) made of a magnetostrictive material arranged in one or more actuators (5, 5a, 5b), which exposes an impulse piston (3) in a pulse cylinder (1) to said hydraulic pressure pulses, whereby mechanical pressure pulses being transferred to a drill steel of the rock drill machine are generated in the impulse piston (3).
