Abstract
A hydraulic piston machine includes a plurality of pistons (12, 14) which are driven by a drive/output shaft (40), guided in an axially displaceable manner in a piston barrel (4) of a housing (2), and, in each case, bound one working chamber (44) into which the pressure medium may be fed via a suction valve (46), and from which the pressure medium may be discharged via a pressure valve (48). The housing (2) includes at least one further housing part (6) which is connected to the piston barrel (4) on the front side. The suction valves (46) and pressure valves (48) are situated in the region of a parting plane (50) between the housing parts (4, 6), in housing receptacles (52, 54), approximately axially parallel to the longitudinal axis of the piston machine.
