摘要:
A radial piston machine and a piston for a radial piston machine include pistons that are movable in the radial direction and are guided along a lifting surface of a cam ring by a roller. The roller is hydrostatically supported by a pressure groove in a sliding bearing surface of a roller cage. The geometry of the pressure groove is configured such that both the leakage is reduced and the lateral support is improved by enlarging hydrostatic and hydrodynamic surface sections.
