  • Patent number: 9879533
    Abstract: A spring return apparatus for elastically prestressing sliding pads against a sliding bearing face of an axial piston machine. The sliding pads are positioned on working pistons mounted axially movably in cylinders of a cylinder barrel that drives a drive shaft including a spring plate and a supporting plate. The spring plate includes a ring region surrounding a central opening, and levers extending radially from the ring region. The levers are arranged spaced apart or distributed uniformly in the circumferential direction, and are elastically flexible and/or elastically pivotable in the axial direction. Every two adjacent levers delimit a receiving region for receiving a tapered section of a working piston or a sliding pad. The supporting plate has a circular ring-shaped supporting region configured to support radially outer end sections of the levers if the supporting plate is arranged concentrically with respect to and axially adjacently to the spring plate.

  • Patent number: 9638180
    Abstract: An axial piston machine of swash plate design includes cylinder bores with respective longitudinal axes that are arranged at an acute angle with the rotational axis and that approach the rotational axis radially in the direction of their control plate-side ends. For each cylinder bore, a point of action of a resulting hydrostatic relieving force, which acts on the cylinder barrel, of the hydrostatic sliding bearing is spaced apart radially with regard to the rotational axis of the cylinder barrel further than a point of intersection of the longitudinal axis of the cylinder bore with the cylinder barrel-side bearing face of the hydrostatic sliding bearing.
