ABSTRACT:
In combination, a pressurized-gas container having a port and a diaphragm valve having a hollow elongated body. A flexible diaphragm is sealingly positioned in the valve. The diaphragm forms a first chamber and a second chamber in the hollow valve. A valve stem is rotatably positioned in the first chamber. A port located in the side of the valve communicates with the second chamber. A short member, affixed in the port, has a central passageway. One end of the short member is adapted to be connected to a source of pressurized gas. A second elongated member, having a central passageway, is positioned in the second chamber of the valve. One end of the elongated member is sealingly affixed to the inside of the wall of the container around the port of the container. One end of the second elongated member forms a valve seat, which is positioned near but not in contact with the diaphragm. A cup member is positioned in the first chamber of the valve. The valve stem can be rotated into a closed position whereby the flat bottom of the cup member sealingly presses the diaphragm against the valve seat.
