Abstract:
A hydrostatic axial piston motor, comprising:a plurality of axially movable pistons mounted in a cylinder drum, each piston having a bore in flow communication with a pressure chamber,wherein each piston is supported on a slide face by an associated sliding block and is hydrostatically compensated,wherein each sliding block has a sliding block plate facing the slide face and is in communication on a side opposite the sliding block plate with an associated piston,wherein a sealing web is formed on the sliding block plate,wherein each sliding block includes a bore extending from a piston side to a sliding block plate side of the sliding block, the sliding block bore being in flow communication with the piston bore of the associated piston such that hydraulic fluid can flow from the pressure chamber so that each piston is hydrostatically compensated on an associated sliding block,wherein the sealing web includes a substantially concave surface, andwherein each sliding block has an outside perimeter, with the concave surface of the sealing web starting from the outside perimeter of the sliding block and extending substantially continuously to the bore of the sliding block.
