ABSTRACT:
The pump assembly comprises means defining a fluid retention chamber having an inlet opening and an outlet opening therein, and check valve means adjacent the inlet and outlet openings, which are operative to limit the fluid flow therethrough to relatively inward and outward of the chamber, respectively, when there is a fluid pressure differential thereacross. The pump assembly also comprises hollow pulse generating means in the chamber, having a volume of less than that of the chamber, but including a normally contracted, resiliently flexible portion which is responsive to a fluid pressure pulse in the hollow of the pulse generating means, to flex in relation to the normally contracted condition thereof. It also comprises inpulsing means which are operative to impart a fluid pressure pulse to the hollow of the pulse generating means, to cause the flexible portion of the pulse generating means to flex and impart a fluid pressure output pulse to a fluid medium retained in the chamber.
