ABSTRACT:
A valve is disclosed for selectively permitting passage of fluid media such as gaseous fuel, from a first location to a second location. A valve body has one end portion defining a cylindrical inner wall surface and a flat annular seat extending inwardly thereof. An end plug is positioned for axial movement toward and away from the valve seat and an annular seal ring is positioned between the end plug and the valve seat and adapted to provide gaseous sealing contact between the end plug and the valve body at a plurality of locations when the end plug is moved to a first closed position which prevents gaseous communication between the first and second locations. In one embodiment the seal ring moves axially with the end plug and in another embodiment the seal ring remains seated and the end plug moves in the axial direction away from the seal ring. Other embodiments provide alternative means to direct the gaseous media from the first location to the second. One application is disclosed wherein the valve is provided in a gas lighter for selectively permitting gaseous fuel to flow from the fuel reservoir to the burner nozzle.
