ABSTRACT:
A one-way valve assembly including an axially extending valve body having an inlet end and an outlet end and with an expandable elastomeric sleeve tightly fitted about the valve body. A cover member encloses the elastomeric sleeve and valve body and presses the sleeve into fluid-tight contact with the valve body at two axially spaced locations. Further, the cover member is fitted tightly onto the valve body adjacent its inlet end. A flowable substance flows from a source through the valve body passing to the outlet and cannot flow back to the source.
