ABSTRACT:
A multi-compartment spout for a fuel dispensing nozzle includes a cylindrical, longitudinally extending outer wall, and at least one interior, longitudinally extending dividing wall. The dividing wall defines a fuel passageway within the spout which communicates with a fuel passageway in the body of the nozzle for dispensing fuel into the fuel tank of a vehicle, and a vapor recovery passageway within the spout which communicates with a vapor recovery passageway in the body of the nozzle for returning fuel vapor to an underground tank and thereby preventing the vapor from escaping into the atmosphere. In a preferred embodiment, the spout includes another interior longitudinally extending dividing wall which defines a shut-off passageway within the spout which communicates with a venturi-vacuum chamber in the nozzle for automatically shutting off the flow of fuel through the nozzle when the vehicle fuel tank is full. The shut-off passageway within the spout has a common interior, longitudinally extending dividing wall with the fuel passageway or the vapor recovery passageway. The spout is extruded of a lightweight metal and the body of the nozzle is molded of a composite resin.
