Abstract
A hydrostatic radial piston machine is useable inversely. The hydrostatic radial piston machine has a distributor in which a flushing valve, a pressure-maintaining valve connected downstream of the flushing valve, and two nonreturn valves are arranged.
Claims15
A hydrostatic radial piston machine, comprising:
- a rotatable housing in which a cylinder block is arranged, cylinder block pistons displaceably arranged in the cylinder block, the pistons supportable on a housing-secured cam ring and each piston bounding a cylinder space in the cylinder block,
- wherein the cylinder spaces are connectable to a first and second main port via a housing-secured distributor configured to supply pressure medium,
- wherein a core element is inserted into the distributor and is configured to connect the distributor to the first and second main ports, the core element configured for rotation relative to the distributor, and
- wherein at least one of a flushing valve, a pressure-maintaining valve, and a nonreturn valve for the first main port is arranged in the distributor, and
- wherein a nonreturn valve for the second main port is arranged in the distributor.
