FIELD: building. SUBSTANCE: hydraulic hammer has power cylinder, distributing device with rotary spool valve provided with channels disposed in plane perpendicular to axis of rotation and directed perpendicularly to spool valve radius. Channels are positioned at a distance from valve generatrix and are connected with discharge line. Valve has two pairs of additional sockets of different length. This makes it possible to control double-acting power cylinder with piston rod serving as striker, featuring asymmetrical movement, i. e. slow idle stoke upwards and rapid working stroke downwards. Rotation is effected with the aid of waste liquid. EFFECT: improved efficiency and simplified design. 5 dwg
