Axial piston machine with housing filled with pressure medium

Abstract

The invention relates to a hydrostatic axial piston machine with a cylinder block rotatably arranged in the housing of the machine and capable of rotating around a rotational axis. The cylinder block is provided with at least one piston recess. A piston in operative connection with a cam plate is arranged longitudinally and displaceably in the piston recess. The cylinder block abutting against a control surface is pressed onto the control surface by means of a spring. The housing is at least partially filled with pressure medium. At least one housing-side resistor, preferably two housing-side resistors, are arranged in a gap between a rotary drive unit assembly formed by the cylinder block and / or the piston and the inner wall of the housing and filled with pressure medium, which is adapted to affect the pressure built up in the housing. The pressure is resulted from a volume current, wherein the volume current is formed in a volume-variable piston protruding area of the piston during the rotation of the cylinder block. The piston protruding area is disposed axially between the cam plate and the end side of a piston outlet opening of the cylinder block containing the piston recess, wherein the segment of the piston that extends out of the piston recess can be put into the piston protruding area.

Description

technical field [0001] The invention relates to an axial piston machine with a cylinder arranged rotatably about an axis of rotation in a housing, wherein the cylinder is provided with at least one piston groove in which a longitudinally slidable The way of shifting is respectively provided with a piston which is operatively connected with the stroke disc, wherein the cylinder body abuts against a control surface and is provided with a spring, which presses the cylinder body against the control surface , wherein the housing is at least partially filled with pressure medium. Background technique [0002] In the case of an axial piston machine, a housing is usually at least partially filled with a pressure medium, for example hydraulic oil, inside which is arranged a rotating drive component consisting of a cylinder and a piston. When the axial piston machine is in operation, disturbing forces arise when the cylinder rotates about the axis of rotation due to the centrifugal f...
