Abstract

A one-way valve for dispensing fluid assures, after the fluid has been dispensed, that any flow of contaminants into the source of the fluid is prevented. The one-way valve has a disc shaped valve body enclosed about the circumferential edge by an elastomeric membrane. Separate passageways conduct the fluid through the valve body with the fluid flowing from one passageway to the other between the circumferential edge and the elastomeric membrane. The valve body has a greater diameter than axial length.
