ABSTRACT:
A displacement pump bypass valve having an integral pressure modulator in a piston of the valve, the piston located in a bore formed through the pump housing between the pump inlet and pump outlet, the piston having an internal, cylindrical expansion chamber which fluidly communicates with the pump outlet via an opening formed through one end of the piston. A modulator disc is located in the expansion chamber for axial movement therein to vary the expansion chamber volume, and a spring in the expansion chamber urges the modulator disc toward the opening in the expansion chamber.
