  • Piston unit
    Patent number: 9334956
    Abstract: A piston unit for a radial piston machine includes a piston and a roller or a roller element. The roller or roller element has a circular cylindrical jacket apart from a chamfer. A hydrostatic pressure- or force-relief element is provided in a contact area between the piston and the roller. The hydrostatic pressure- or force-relief element forms a pressure field in the contact area. The roller or roller element also has one or two end-face holes. Due to the hole(s), the roller is slightly weakened at the associated end section such that Hertzian stress is reduced at the same associated end section.
