Abstract
A vapor recovery nozzle is disclosed in which the main body of the nozzle has the vapor passage located above the fluid passage, so that the fluid valve is separated from the top of the nozzle by the vapor passage. Thus the valve may only be removed through the bottom of the nozzle by removing the trigger mechanism and removing the vacuum tripping mechanism which is also connected to the trigger mechanism. Removal of the tripping mechanism is also made easily determinable by the use of a soft aluminum seal over the top opening of the trigger mechanism. The tripping mechanism is responsive to displacement of the vapor recovery shroud to prevent dispensing fuel unless the nozzle is in the fill tank. Other improvements to prior art vapor recovery nozzles include an improved trigger mechanism having a camming surface to engage the stem of the main valve.
