Title: Refill-preventing valve for non-refillable containers
Inventor: BAKER GEORGE D
IPC: F17C13/04
Filed: 1993-11-10
Abstract: A non-refill valve for a non-refillable container, comprising a valve body having an inlet and an outlet and a passage through the valve body interconnecting the inlet and the outlet. A valve stem slides in the passage and has an axial passageway that extends partway therethrough and that terminates laterally in a passageway that extends through a side wall of the stem intermediate the ends of the stem. A ball in the stem rests on a seat on the stem and closes the valve stem passageway against the flow of gas froze the outlet towards the inlet. A first spring urges the ball against the seat to permit flow of gas only in a direction from the inlet to the outlet by displacing the ball from the seat against the action of the first spring in an open position of the valve.      A second spring urges the stem in the direction of the flow of gas from the inlet to the outlet, and a seal acts between the stem and the valve body. The second spring urges the seal into sealing relation with the valve body in a closed position of the valve, whereby when a coupling is attached to the valve body, the coupling urges the stem in a direction opposite the first-mentioned direction and against the action of the second spring to move the seal out of sealing relation with the valve body, thereby to establish communication between the inlet and the outlet when the pressure of a gas in the inlet is sufficient to move the ball off the seat against the action of the first spring.
