ABSTRACT:
A combined unloading, relief, and load compensating valve has a poppet controlling flow between an inlet and an outlet and is spring biased to closed position. The poppet has a piston slidable in a cylindrical chamber in which the hydraulic pressure may be remotely controlled. The poppet is exposed over a small differential area to inlet pressure tending to open the poppet. The poppet and the piston are constructed as a cartridge which contains a second poppet valve and piston also controlling flow from the inlet to the outlet and is spring-biased to closed position, but openable by inlet pressure acting over a small area and the piston of the second poppet has approximately the same small area. Both pistons are connected to the common control passageway and the relative areas and spring bias forces are such that the first poppet acts as an unloading valve opening only when the control pressure is near zero and the second poppet acts as both a load compensator and a maximum pressure relief valve.
