    摘要: A variable-displacement, axial piston-type hydraulic fluid pump having a pump housing (12) is provided with co-operating pump rotational speed, thrust plate position, and working pressure operating-condition sensor assemblies (100) that are partially contained within the pump housing (12), that are partially contained within a separate position sensor housing (110) which is removably secured to the pump housing (12), and that are sealed against high-pressure fluid leakage using only static resilient fluid pressure seals (114).

    摘要: The variable displacement axial piston pump (10) has a plurality of piston bores (32) each connected to an inwardly angled fill port (120). The fill ports (120) extend from the piston bores (32) inwardly to the working face of the barrel (22) to reduce the diameter of the fill circle of a pump. This decreases the velocity that must be attained by incoming fluid to thereby increase the operating speed at which the pump may be driven where the pump is filled at atmospheric pressure.
