DIFFERENTIAL PRESSURE CONTROL

摘要

Disclosed is a load sensing hydraulic control system for use with a vehicle. The load sensing hydraulic control system comprises an orifice receiving a maximum pressure signal, the orifice being in fluid communication with a pump displacement controller, a check valve receiving the maximum pressure signal and bypassing the orifice when the maximum pressure signal is greater than the pump control signal, and a load sense regulator in fluid communication with the pump displacement controller, the load sense regulator maintaining a pressure differential over the orifice below a predetermined level.
