  • Patent number: 7766039
    Abstract: A quick connect fuel hose connector for connecting an LP fuel hose to a threaded inlet fitting on a vehicle or appliance fuel tank comprises an annular body having an inlet for fuel at an inner end and an outlet for fuel at a recessed opening in an outer end. Latch members pivotally mounted in slots on opposite sides of the body engage and latch the connector to the fuel tank inlet fitting when the connector is fitted over the inlet fitting. A lost motion spring seal maintains a tight seal between the connector and the inlet fitting. A replaceable nose seal on an outlet valve in the connector provides an improved sealing connection between the connector outlet valve and the fuel tank inlet valve.

  • Publication number: 20100078084
    Abstract: A valve assembly includes a housing having a first chamber, a second chamber, and a valve seat disposed therebetween. A valve head disposed in the housing and is moveable between an open position and a closed position. The valve head defines a bore extending along an axis from the first chamber to the second chamber when the valve head is in the closed position. A valve stem is disposed in the bore and is coupled to the valve head in the bore for moving the valve head between the open and closed positions. The valve assembly allows for selective fluid communication between the first and second chambers to alleviate pressure differences between the first and second chambers. In one embodiment, the valve stem moves in the bore between a sealed position and an unsealed position. In another embodiment, a check valve is disposed in the bore.

  • Publication number: 20090250118
    Abstract: A self-cleaning bleeder valve comprises an annular housing that is mounted in an opening in a pressure vessel, and a valve member that screws into the housing for movement toward and away from an orifice opening in the housing. The valve member includes a gasket seal and orifice drill at an inner end of the valve member. The orifice is positioned such that when the valve member is screwed into the annular housing, the drill extends through the orifice, automatically cleaning the orifice while restricting the rate of gas flow out of the orifice to the space between the drill and the orifice.

  • Publication number: 20080135108
    Abstract: A gas convenience outlet for connecting an outdoor grill or other gas fired appliance to a home gas supply or other fixed position source of natural gas or liquid petroleum gas comprises a case having an open interior and an openable cover with a manifold mounted in the interior. The manifold has an inlet operatively connected with a supply of fuel gas and one or more outlets. A primary manual shutoff valve located in the interior is operatively connected with the manifold outlet. The outlet includes an outlet connector extending outside the interior. The connector has a standardized fitting that releasably couples in gas tight engagement with one or more gas fired appliances by means of standardized appliance connectors without adaptors and without loss of performance.

  • Patent number: 7051755
    Abstract: An adjustable floating seal piston type pressure regulator valve of the type wherein a spring biased piston engages a floating seal in a regulator body valve chamber to open and close a valve seat outlet in the valve chamber. The valve seat comprises a separate member from the regulator body and is adjustably movable in the valve chamber toward and away from the piston, such that movement of the valve seat toward the piston serves to lower a regulated outlet pressure and movement of the valve seat away from the piston serves to increase the regulated outlet pressure. The valve seat member is moved by an adjustment screw that is externally accessible by an adjustment tool. A tubular expansion chamber surrounds the regulator body and provides an enlarged expansion chamber that reduces valve recycle time. Convolutions or ribs in the expansion chamber housing enhance heat through transfer to the valve gases.
