Abstract:
1. A dual input valve comprising: a valve stem having a first end and a distal end; a compressed air valve formed on the valve stem between the first end and the distal end, a captured o-ring is held in a circumferential groove on the compressed air valve; a catalyst valve ball interfaced with the distal end of the valve stem; a dual valve housing, the dual valve housing having a catalyst input port in fluid communication with a catalyst valve seat, a compressed air input port in fluid communication with a compressed air valve seat, a mixing chamber in fluid communication with the catalyst valve seat and the compressed air valve seat, and an output port in fluid connection with the mixing chamber; and a spring, the spring urging the catalyst valve ball towards a closed position, therefore urging the compressed air valve towards the closed position, in which the compressed air valve and captured o-ring are seated against the compressed air valve seat and in which the catalyst valve ball is seated against the catalyst valve seat, thereby blocking flow of a catalyst from the catalyst input port into the mixing chamber and blocking flow of compressed air from the compressed air input port into the mixing chamber.
