Abstract
An axial piston machine includes a housing part, a drive shaft, which is mounted in the housing part, and a cylinder drum, which is connected to the drive shaft in a rotationally fixed manner and which accommodates a plurality of pistons. Each of the pistons bound a working chamber and are supported on a swashplate. The working chambers can be connected in alternation to a high-pressure channel and to a low-pressure channel, which extend in the housing part. An insert part is rigidly inserted into the housing part. A control surface of the insert part is directly opposite the cylinder drum. The insert part has a high-pressure channel section and a low-pressure channel section, which have approximately kidney-shaped opening areas in the control surface. The other openings of the high-pressure and low-pressure channel sections opposite the opening area in the control surface are formed radially on the insert part.
