ABSTRACT:
A gas spray valve permits easy recharging of gas containers after use. The gas spray valve is of considerable strength and rigidity and can be manufactured in a less costly manner. One of the openings of a gas conduit of a valve pin is positioned so that, when the valve pin is in the raised position, the opening is positioned above a second seal ring and, when the valve pin is pushed into a first stop position, the opening is positioned below the second seal ring. When the valve pin is in the raised position, a bottom end of the valve pin is positioned above a first seal ring, and as the result, the interior of a gas container is connected with a metering chamber. When the valve pin is pushed into a second stop position, the opening of the gas conduit is positioned below the first seal ring so that the interior of the gas container communicates with the gas conduit. This permits recharging of the gas container with the gas.
