Abstract
An apparatus for holding a fluid under pressure, including a container for containing the fluid under pressure and a valve mounted on the container. The container has a passage leading to the exterior of the container, and the valve has an actuator for moving the valve between closed and open positions. A locking device is responsive to movement of the actuator to a position in which the valve is open to lock the actuator against movement that would close the valve. Consequently, the valve is locked in the open position.
