ABSTRACT:
A spout gland is provided for a vapor recovery fuel dispensing nozzle assembly having a nozzle body and a nozzle spout assembly. The nozzle body includes a body fuel flow path having an inlet and an outlet and a body vapor recovery path, and a venturi valve in the body fuel flow path. The spout assembly is connected to the body and defines a spout fuel flow path and a spout vapor recovery path in communication with the respective flow paths in the nozzle body. The spout assembly includes a spout tube defining the spout fuel flow path, the spout gland, and a vapor guard. The spout gland has a diameter, in part, that is larger than the diameter of said spout tube to define a generally forwardly opening annular channel around the spout tube. The gland has at least one opening in a wall thereof to place the channel in communication with an area external of said spout gland and the body vapor flow path. The vapor guard is secured to the spout gland so that the channel defined by the vapor guard and the spout tube is in communication with the channel defined by the spout gland and the spout tube, to define the spout assembly's vapor recovery flow path. The spout gland thus both secures the vapor guard to the spout tube, and places the spout assembly vapor recovery flow path in communication with the body vapor recovery flow path.
