Abstract

A pressure control valve assembly for controlling fluid pressure to an actuator, the pressure control valve assembly being in fluid communication with an actuating fluid pump and being disposed intermediate the actuator and the pump, includes an energy storage component, the energy storage component acting on a certain volume of actuating fluid under pressure, the stored energy being selectively releasable to the actuator for augmenting the actuating fluid pressure in the actuator. A method of control is further included.
