ABSTRACT:
By externally mounting a resiliently flexible member about a valve stem so as to biasingly engage the valve stem with the valve housing in the closed position, a unique, self-contained, captured valve assembly is provided. In the preferred embodiment, the flexible biasing member comprises a rubber material which peripherally surrounds the valve stem and the valve housing. This valve assembly is particularly useful in gas lighters of the butane fuel type, since the preferred embodiment provides a seal against leakage and secondary ignition.
