  • PRESSURISED FLUID CYLINDERS
    Publication number: 20090266816
    Abstract: A gas cylinder (100) in the neck (20) of which is installed a balanced valve (26). The valve is fitted in the outlet of the cylinder and its output emerges into a recess (22) which opens to the top surface (23) of the cylinder. Thus the valve is protected from physical damage. A thread (27) in the bore enables the attachment of fittings such as a regulator or a filling device (not shown) which cooperate with the valve (26) to control passage of gas from or into the cylinder.

  • Combination valve and regulator with vented seat for use with pressurized gas cylinders, particularly oxygen cylinders
    Publication number: 20050205140
    Abstract: A combined valve-regulator apparatus, for safely regulating the flow of combustible gases such as oxygen. A compressible o-ring is used to provide controllable sealed seating of the valve and regulator during operation. A system is provided in the valve-regulator apparatus for venting the o-ring seat elements, to minimize undesirable ballooning or extrusion otherwise resulting from dynamic pressures and changing forces due to rapid gas flows through the regulator.
