Abstract:
1. A poppet valve assembly for preventing the exit of compressed gas from a container through a flow control valve, said poppet valve assembly comprising: a hollow member constructed and arranged to be retained within the flow control valve; a spring-less sliding valve retainable in a normally open condition by physical contact with said hollow member, said normally open condition allowing compressed gas to flow out of the container into the flow control valve; said spring-less sliding valve including a surface in contact with the compressed gas within the container; said spring-less sliding valve further including a fixed portion including at least one passage therethrough to enable the compressed gas to contact said spring-less sliding valve; wherein when said hollow member is removed, the force of the compressed gas within the container causes the spring-less sliding valve to change from its normally open condition to a closed condition, thus preventing the rapid escape of gas from the container.
