Abstract

An axial piston machine may include a rotor having a shaft rotatably mounted in a housing. A plurality of cylinders may be arranged annularly around the rotor. A plurality of pistons may each be disposed within each of the plurality of cylinders and may be constructed and arranged to selectively translate within each of the plurality of cylinders. Each of the plurality of cylinders may be disposed within a cylinder head and may be in operative communication with an inlet opening defined in the cylinder head and at least one outlet opening defined in the housing. An auxiliary outlet rotary slide valve may be operatively connected to the shaft in a rotationally fixed manner. The auxiliary outlet rotary slide valve may comprises an auxiliary outlet rotary opening constructed and arranged to connect to a vent duct of one of the plurality of cylinders based on an angle of rotation, and may vent the one of the plurality of cylinders. At least a portion of the auxiliary outlet rotary slide valve may comprise a material constructed and arranged to reduce a sliding friction resistance, and wherein the material comprises one of a carbon containing material or a polymer containing material.
