摘要
A load sensing circuit of a load responsive direction control valve including a device for sensing load pressure signals identifying those load pressure signals as positive or negative and transmitting those identified positive or negative load pressure signals to the throttling compensator control of the load responsive valve, while also transmitting the positive load pressure signal to the pump control. The load pressure signals from individual cylinder ports, together with the signals related to the direction of displacement of the controlled load, are transmitted electrically to an electrical logic circuit, which identifies the load pressures as positive or negative and generates the required electrical signals to the electrohydraulic controls, which connect the positive or negative load pressure to throttling compensator controls of the load responsive direction and flow control valve.
