  • Hydrostatic axial piston machine and retention plate
    Patent number: 9506456
    Abstract: An axial piston machine has a cylinder connected to a shaft and a multiplicity of pistons guided by the cylinder and supported by sliding shoes on a swashplate. Each sliding shoe has a sliding shoe collar and a sliding shoe head, and is held in place in a direction of a contact position by an annular retraction plate. An end face segment of the retraction plate engages an annular surface between the sliding shoe collar and the sliding shoe head, and each sliding shoe collar passes through an associated aperture in the retraction plate and connects to a corresponding piston. A surround is formed in the retraction plates at the head of each sliding shoe, and is configured to fit around an axial segment of a circumference of the sliding shoe head in a direction toward the swashplate.
