Abstract
A dual valve assembly for use with a dispensing apparatus including a pump and a plurality of fluid containers. The valve assembly includes a housing containing an elastomeric regulator wherein the regulator includes a diaphragm portion for controlling fluid flow through the housing, and a vent valve structure for opening and closing air passages to supply air to the containers. The diaphragm portion includes an orifice, and the diaphragm portion is movable into and out of contact with a seat defined on the housing to control fluid flow from the containers and through the orifice during actuation of the pump. In addition, the vent valve structure includes a pair of vent membranes which open vent openings to the containers in response to negative pressure applied from the pump.
