| 20090165870 | Manifold assembly - A manifold assembly for use with compressed gas cylinders, apparatus having CGA-870 compliant fittings and refilling/conserving apparatus to permit a user to selectively direct compressed gas from the refilling/conserving apparatus to the CGA-870 compliant apparatus and/or coupled compressed gas cylinder. The assembly includes a housing having a fill interface having at least one fill port, an outlet interface having at least one outlet port, and a cylinder interface having at least one port where a first fluid conduit fluidly coupling the outlet interface with the cylinder interface and a second fluid conduit fluidly coupling the inlet interface with the cylinder interface wherein the second fluid conduit has no unidirectional flow restriction means. To prevent back flow from the outlet port to the cylinder port, a one-way valve is used. In certain embodiments, one end each of the first and second fluid conduits separately terminate at the cylinder interface. | 07-02-2009 |
