摘要： A vapour recovery nozzle (10) is disclosed in which the main body (11) of the nozzle has the vapour passage (36) located above the fluid passage (16), so that the fluid valve (22) is separated from the top of the nozzle by the vapour passage. Thus the valve may only be removed through the bottom of the nozzle by removing the trigger mechanism (73) and removing the vacuum tripping mechanism (81) which is also connected to the trigger mechanism. Removal of the tripping mechanism is also made easily determinable by the use of a soft aluminium seal (123) over the top opening of the trigger mechanism. The tripping mechanism is responsive to displacement of the vapour recovery shroud (30) to prevent dispensing fuel unless the nozzle is in the fill tank. Other improvements include an improved trigger mechanism having a camming surface (80) to engage the stem (55) of the fluid valve (22).
