ABSTRACT:
A pulse hydraulic system is disclosed comprising, in combination a hydraulic sump for supplying the system with hydraulic fluid, one or more hydraulic pumps taking suction on the sump for increasing the pressure of the hydraulic fluid exiting the sump, a pulse generator fed by the discharge from the pump(s) for creating pulsed pressure of the hydraulic fluid output therefrom, an actuator coupled to the pulse generator for doing work, and one or more accumulators coupled between at least one of the pump(s) and the pulse generator, between the pulse generator and the actuator, and between the pulse generator and the sump for storing and supplying pressurized hydraulic fluid to the system. The addition of one or more pulse intensifiers to a pulse hydraulic system increases the overall system efficiency.
