Load sensing circuit of load compensated direction control valve

In a load responsive system including a fluid power actuator operable to control a positive or negative load W, a source of pressure fluid, fluid exhaust means, flow control means of said load responsive system including a positive and a negative load pressure throttling control and first valve means operable to selectively interconnect said actuator with said source of pressure fluid and said fluid exhaust means and to direct the flow of fluid subjected to positive type and negative type load pressures, actuating means responsive to a control signal and operable to control direction of displacement and position of said first valve means, first signal generating means operable to generate a first electrical signal in response to direction of displacement of said first valve means, second signal generating means operable to generate second electrical signal in response to said laod pressure in said fluid power actuator, electric logic means having a positive and a negative load pressure identifying means and operable to process said first and said second electrical signals and to identify the type of said load pressure and operable to produce at least one actuating signal, and second valve means responsive to said actuating signal and operable to supply said identified load pressure to the respective positive or negative load pressure throttling control.
