VAPOR RECOVERY NOZZLE Abstract of the Disclosure. A vapor recovery nozzle for dispensing fuel, such as gasoline, that can be latched to the filler neck of a tank to be filled. An articulated seal is provided that sealingly engages the filler neck and, when so engaged, forces a piston relatively toward the nozzle to open the flow passageway through the nozzle for the vapors. A valve is provided that is actuated by the piston which, when the nozzle is not in the filler neck, closes to prevent the escape of any vapors that might be contained in the vapor recovery system. Furthermore, the piston carries a valve operating means that functions in conjunction with a flow valve that is located in a conduit ex- tending through the nozzle. This conduit is utilized to sense when the liquid level in the tank rises above the end of the conduit extending from the nozzle to automatically shut off the nozzle and prevent flow of fuel therefrom. The arrangement of the nozzle is such that the vapor recovery passageway extending therethrough is sealed to prevent the entrance of air or other vapor into the system except as may come from the fuel tank. -1a-
