ABSTRACT:
A valve nozzle structure include a valve stem. On the valve stem is a collar flange and along both sides of collar flange is a series of tapered retainer lips. A passage is formed through the valve stem, a flexible valve sleeve is inserted on the tapered retainer lips on one side of the valve stem, and a slit is incised in the valve sleeve, with the slit normally in a sealed state of closure. The foregoing structure permits gas to flowing towards the valve sleeve to travel only in a single direction through the passage.
