摘要: A torque limiter control sets the limit of power which may be absorbed by a pump. A feedback system adjusts the displacement of the pump in responses to changes in the pressure of working fluid at the pump outlet to maintain a set power.

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.
