<p>A one-way valve assembly including an axially extending valve body (24) having an inlet end (18) and an outlet end (20) and with an expandable elastomeric sleeve (14) tightly fitted about the valve body (24). A cover member (16) encloses the elastomeric sleeve (14) and valve body (24) and presses the sleeve (14) into fluid-tight contact with the valve body (24) at two axially spaced locations. Further, the cover member (16) is fitted tightly onto the valve body (24) adjacent its inlet end (18). A flowable substance flows from a source through the valve body passing to the outlet (54) and cannot flow back to the source.</p> |
