Abstract
A valve assembly for a fluid dispensing unit, particularly for a soap dispenser, comprising a resilient valve member secured within a chamber. Valve member comprises a sealing member, a support member and a securement member. The support member carries sealing member at one end and securement member at the other end. The valve member when secured within the chamber is under compression with the sealing member biased by the support member engaging and sealing the inlet port of the chamber to fluid flow therethrough other than fluid flow under a pressure differential across sealing member sufficient to resiliently deflect the sealing engagement. The valve member is formed entirely from recyclable plastic as an integral unit by injection molding.
