摘要:
A hydraulic control system for a variable displacement pump, comprising a prime mover for driving the variable displacement pump, a fixed displacement pilot pump driven by the common prime mover, a pressure compensating valve connected to the pilot pump and the variable displacement pump, a cut-off control valve connected to the pressure compensating valve and the variable displacement pump, and a servo booster connected to the cut-off control valve and the pilot pump for controlling the displacement of the variable displacement pump.
