More Information
Summary:The invention relates to an impulse generator (2) for a rock breaking tool, which comprises a propulsion chamber (6) for receiving a pressurizeable liquid volume (8), and an in the propulsion chamber (6) received impulse piston (10), where the impulse piston (10) is arranged for transfer of pressure peaks in the liquid volume (8) into impulses in the tool (12), whereby transfer of energy from a propulsion mechanism (14) into impulses in the tool (12) is effected by volume reduction of the propulsion chamber (6), whereby the impulse piston (10) is driven forward by a pressure peak in the propulsion chamber (6). The invention also relates to a hydraulic impulse tool comprising an impulse generator (2).
