Abstract:
A hydrostatic axial piston machine having a drum-like cylinder block which is supported in a manner fixed against rotation on a driving or output shaft and is provided concentrically and parallel to its center line with cylinder openings (8) in which axially displaceable pistons (10) are arranged which are supported via spherical heads on a slanting disk,wherein the cylinder openings (8) opposite the slanting disk sweep over roughly kidney-shaped low pressure (3) and high pressure (2) control openings of a control body (1), between which reversing regions boreholes (4, 5, 6, 7) are located, at least one (5) of the boreholes (4, 5) opening in the reversing region of the control body (1), is connected to a high pressure side or the high pressure control opening (2) by a line, and a control piston restrictor (12) controlled by the high pressure is arranged in the line (18, 19) which varies a restrictor opening (20) in response to the high pressure in the line.
