Abstract: A hydrostatic axial piston machine includes a pot-like housing, a connection plate that closes the pot-like housing, a rotatably mounted cylinder drum, and pistons arranged in cylinder chambers of the cylinder drum. The cylinder chambers are each alternately connected via a cylinder chamber opening to a low-pressure control opening and a high-pressure control opening of a resting control part. The control part has two switching regions located between the low-pressure and high pressure control openings. A piston reverses its movement direction in a dead center within the two switching regions. In the switching region, the cylinder chambers are connected via a connecting line to a fluid volume arranged in the housing. The fluid volume extends between the connection plate and the housing such that it is sealed to an interior by the connection plate and the housing.

Abstract: On an inner surface of a housing, a nozzle for jetting operation oil is provided at a position opposite to an outer circumferential surface of a cylinder block. With this configuration, by spraying the operation oil from the nozzle to the outer circumferential surface of the cylinder block during rotation of the cylinder block, this operation oil can remove frictional heat generated by sliding between a piston and a cylinder, and seizure of the piston and seizure of the cylinder can be prevented.

Abstract: A gap between an outer peripheral surface of a cylinder block and an inner periphery surface of a housing serves to reduce an agitation resistance of an operating oil with a simple arrangement. So this reduces an agitation loss and improves or increases a conversion efficiency between a hydraulic energy and a rotational energy.
