Hydraulic axial-piston machine having rotating displacers

摘要

The hydraulic axial-piston machine having rotating displacers contains a casing (1) in which a cylinder block (2) with pistons is arranged. The cylinder block (2) has two rows of cylinder bores (7, 8) which are distributed on concentric circles. The cylinder bores (7, 8) are connected, by means of ducts (18, 19) fashioned in the cylinder block (2), to arcuate orifices (20, 22, 21, 23) of a control disc (24). The orifices (20, 22, 21, 23) communicate, by means of individual ducts (33, 31, 32, 30) fashioned in the control disc (24), with its inlet port hole (26) and outlet port hole (27), respectively. <IMAGE>
