Abstract
A liquid dispensing nozzle has a bellows secured to its body and disposed in spaced surrounding relation to its spout to form vapor return means therebetween. Sealing means, which can be integral with the bellows or separate therefrom, is disposed in surrounding relation to the spout so as to be movable relative thereto. The spout has a retainer thereon between the free end of the spout and the sealing means. The retainer has a curved surface, which is preferably spherical, on its end for engagement with a sealing surface of the sealing eans to form a seal therebetween to seal the vapor return means formed between the bellows and the spout from the atmosphere when the spout is not disposed in a fill pipe of a vehicle tank to be filled. When the spout is disposed in the fill pipe opening of the tank to be filled, the sealing surface of the sealing means engages the fill pipe to seal the fill pipe opening so that the vapors escape from the tank to the vapor return means formed between the bellows and the spout and from there to a vapor recovery passage in the nozzle body.
