A hydrostatic positive-displacement machine, in particular a hydrostatic axial piston machine, having a cylinder drum with at least one cylinder, in which a longitudinally displaceable piston is received, which is supported directly or indirectly by a support portion on an inclined plane of the positive-displacement machine. An outer circumferential surface portion of the piston is in bearing contact with an inner circumferential surface portion of the cylinder.

Hydrostatic positive-displacement machine piston for the hydrostatic positive-displacement machine, and cylinder drum for the hydrostatic positive-displacement machine

A hydrostatic positive displacement machine has a cam ring for adjusting the displacement volume thereof. This cam ring is guided in translation by approximately diametrically arranged outer circumferential surface segments on associated inner surface segments of a housing of the positive displacement machine.

A cooling and lubricating arrangement of tribological contact areas is disclosed. The arrangement includes tribological contact areas that slide over one another, of which at least one contact area has a surface contour with surface depressions in which a lubricant is stored. The surface contour forms a number of elongate grooves, the gap heights of which, at least in respect of respectively two adjacent grooves, are preferably different.

Rinsing arrangement for tribological contact areas and rotary vane pump with such an arrangement

A pump unit includes a main pump () and a charge pump (), the pump capacity of which is adjustable via an adjusting element. To adjust the pump capacity of the charge pump (), an adjusting element of the charge pump () is acted upon by an adjusting force which is dependent on the inlet pressure of the main pump ().
