Abstract

A diaphragm pump especially suited for use in a high pressure application. The pump is devised to replenish any hydraulic fluid lost from a motor chamber, especially that fluid forced past the seals circumscribing a reciprocating plunger that is partially inserted into the motor chamber and is used as a means to alternately generate and release the high pressure that must be generated in the motor chamber to overcome the opposing high pressures existing in a pumping chamber containing a transient fluid. The motor chamber and the pumping chamber are separated by a diaphragm that is displaced according to the pressures in the motor chamber and the pumping chamber. Whenever the pressure generated in the motor chamber is such that the pressure in the pumping chamber is overcome, the pumping chamber shrinks in size and the transient fluid is expelled from the pumping chamber. Whenever the pressure in the motor chamber is released, the pumping chamber increases in size and the transient fluid is drawn into the pumping chamber.
