ABSTRACT:
A liquid dispensing nozzle has an eccentrically mounted seal at one end of a bellows, which is disposed in spaced relation to the spout of a nozzle to form an annular vapor return passage therebetween, to engage a fill pipe of a tank to form a seal therewith when the spout is disposed therein so that vapor flows from the tank to the annular vapor return passage of the nozzle. The seal includes a compressible member for engaging the fill pipe, a swivel plate, and a cap surrounding the bellows whereby the seal is removably fastened to the bellows for easy replacement. The swivel plate is pivotally connected to a spring, which surrounds the spout, so that the seal can pivot about two orthogonal axes with respect to the spout. The pivotal connection of the swivel plate to the spring is on top of the spout so that the maximum force of the spring is applied to the maximum eccentric surface of the seal.
