Abstract:

A system is disclosed for dispensing fuel, e. g. gasoline, from a reservoir tank into a consumption tank as in an automobile. The system incorporates two fluid flow channels, first a channel for liquid fuel and second a return line for fluid vapors. The channels include flexible hoses extending from a pump to a dispensing nozzle with rotatable or swiveled couplings. The couplings include two mating members affixed together to provide a fluid seal and relative rotation to accommodate swivel movement. One coupling member includes a fastening section which may be threaded to affix the coupling to a rigid structure, e. g. pump or nozzle. Also, the one member includes a somewhat cylindrical section defining an external, concentric groove for receiving a ring of nylon-like material. The cylindrical section of the one member is telescopically received within the other member which defines an internal groove for locking engagement with the nylon-like ring. The second member further includes a plurality of O-rings to accomplish a fluid seal with the cylindrical section.
