Abstract
A hydraulic pressure control system having a variable displacement pump fluidly connected to a hydraulic motor. The pump provides flow to a first circuit upon demand. Remaining flow is provided to a second circuit. The second circuit includes a pilot controlled pressure reducing valve that adjusts the pumps outlet pressure based upon a sensed loads taken from a conduit between the pressure control valve and an active flow regulator valve.
