ABSTRACT:
In a liquid dispensing pump of the deformable diaphragm type, the diaphragm includes an encircling marginal flange which is clamped between the pump housing members to function as a sealing gasket, with integral portions of the flange extending across the inlet and discharge passages leading to and from the pump chamber to function as flap type intake and outlet valves having their free edges defined by apertures in the flange through which the liquid may pass when the valves are unseated.
