<p>PURPOSE: To provide a hydraulic piston machine with better operational behavior and longer service life. CONSTITUTION: This machine includes a cylinder drum 3 and a control plate 5, wherein the control plate has at least one high-pressure part 6, at least one low-pressure part 7, and a contact surface 10 pressed against it while the cylinder drum is operating. This hydraulic piston machine 1 includes a friction- reducing layer 11 in at least the contact surface, and the contact surface 10 in the range of the low-pressure part includes a recessed range forming a gap 13 between the cylinder drum 3 and the control plate 5.</p> |
