The hydraulic hammer (10) comprises a power cell housing 11 to form a hydraulic inlet 12 and hydraulic outlet (13). Equipment mounting portion 20 forming a plurality of pin receiving bore (21) is attached to the power cell housing (11). Work tools 30 is partially received in the power cell housing 11, it may be moved to the power cell housing (11). Switching the spool valve member 40 comprises a power cell is located in the housing 11, a first position and a second position, and movable between a control hydraulic surface 41. Sleeve / liner assembly 50 is located within the power cell housing (11) to form a center line (51). A piston (70) with a plurality of hydraulic surface is the center line between the sleeve / liner assembly is located in 50, work tool 30, a first position and a work tool that is not in contact with the second position 30, which is in contact with the (51 ) can move along. Switching spool control hydraulic surface 41 of valve member 40 is exposed to fluid pressure in the switching path (91) including a segment formed by the sleeve / liner assembly 50.
