Abstract
An axial piston machine has a central bore connected via a connecting duct with the pressure carrying duct of a mirror member. The central bore together with the central pivot acts as a pressure cylinder which exerts a central bearing pressure on the cylinder drum and the mirror member and acts against lifting forces which threaten to lift the mirror member off its slideway. With this additional force it is possible to enlarge the orifices or slots on the rear side of the mirror member so that the area of tilt of the cylinder drum with the mirror member is enlarged. The additional central bearing force applied by the present invention is supported on the drive flange via the central pivot and urges the mirror member against the slideway so as to ensure at all times a secure engagement of the mirror member even when the pressure sides change, that is, a changing direction of tilt of the cylinder drum in a reversing pump.
