Hydrostatic axial piston machine and retention plate

A hydrostatic axial piston machine, comprising:

• a cylinder connected to a shaft such that the cylinder conjointly rotates with the shaft;
• and
• a multiplicity of pistons guided in the cylinder and supported via sliding shoes on a swashplate, wherein:
• each of the sliding shoes includes a sliding shoe collar and a sliding shoe head, and is held in a direction of a contact position by an annular retraction plate;
• an end face segment of the annular retraction plate engages an annular surface between the sliding shoe collar and the sliding shoe head of each of the sliding shoes;
• the sliding shoe collar of each of the sliding shoes passes through an associated aperture in the annular retraction plate and connects to a corresponding one of the multiplicity of pistons;
• a surround is formed at each aperture of the annular retraction plate;
• and
• each surround fits around an axial segment of a circumference of the sliding shoe head of a corresponding one of the sliding shoes in a direction toward the swashplate.
