Abstract
A liquid dispensing nozzle has a check valve mounted adjacent the front of the nozzle body to seal an annular vapor return passage, which is between the spout and a bellows, to prevent communication through vapor return passages in the nozzle to the vapor recovery equipment unless the spout is disposed in the fill pipe of a vehicle tank. One of the elements of the check valve for forming this seal is mounted on the spout and the other is mounted on a member, which is slidably supported by the nozzle body.
