  • Radial piston engine with brake
    Patent number: 9777573
    Abstract: A radial piston motor comprises cylinder-piston units arranged in a star shape, a housing, an output shaft, an inner axial housing collar, an outer axial shaft collar, an output flange, an output shaft, and a brake positioned at least in certain sections between the inner axial housing collar and the outer axial shaft collar. The output flange is attached to the output shaft. The output flange is attached to the shaft collar radially outside the shaft collar.

  • 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.

  • TRIBO SYSTEM FOR A PISTON UNIT AND HYDROSTATIC RADIAL PISTON ENGINE EQUIPPED THEREWITH
    Publication number: 20140165825
    Abstract: A tribosystem for a piston unit includes the piston unit having a piston and at least one rolling body mounted rotatably in a rolling-body receptacle of the piston. The rolling-body receptacle is substantially comprised of a bearing material having a PEEK/PTFE matrix. A surface of the at least one rolling body is polished.
