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