Abstract:
An axial piston machine is provided. A housing of the machine receives an eccentric disk and a rotatably mounted cylinder drum. The drum has cylinders and pistons. The pistons are reciprocatable in the cylinders. The ends of the cylinders project from the cylinders and are supported via sliding blocks against a sliding surface on the eccentric disk. The sliding blocks are held in abutment with the sliding surface through a holding-down device. A pressure prevailing in a pressure chamber under the sliding blocks by a throttle point partially compensates a force that is exerted by the holding-down device on the sliding blocks, through a hydraulic pressure between an annular seating surface of the sliding blocks and a support surface of the holding-down device.
