Abstract: The valve is designed for the ejection of a plurality of different gases from within the valve, simultaneously, by having a plurality of plenum chambers within the chamber of the valve, and a poppet therein, that are charged with gases under pressure. The gases are sealed within the respective plenum chambers by the action of a spring that urges the poppet against a gas exit port associated with each plenum chamber. Ejection of the gases is accomplished by the application of an electrical current into a coil surrounding the poppet which produces an electromagnetic field that causes a non-ferrous hammer to be driven away from the coil and strike the poppet. Upon being struck by the hammer, the poppet is driven off of the plurality of gas exit ports thereby allowing the gases to be ejected, simultaneously, from the respective plenum chambers into a region of lower pressure.
