A fuel dispensing nozzle includes a housing having a hollow main body portion and a handle portion with a hand-grip spaced from the main body portion, an elongate nozzle body mounted in the main body portion of the housing and having a fuel passageway extending longitudinally therethrough in a generally straight line devoid of any abrupt changes in direction, a main valve for controlling the flow of fuel through the nozzle, a manually operable valve actuator, a spout having three integrally formed passageways comprising a fuel passageway, a vapor recovery passageway and a shut-off, venturi-vacuum passageway, a vapor recovery passageway through the main body and handle portions of the housing, a venturi-vacuum device for shutting off the flow of fuel through the nozzle when the vehicle fuel tank is full, an attitude responsive device for deactivating the main valve when the nozzle is not in the proper attitude for insertion of the spout into the fill opening of the vehicle fuel tank and an attitude responsive valve in the vapor recovery passageway for closing the vapor recovery passageway when the nozzle is not in position for insertion of the spout into the fill opening of the vehicle fuel tank.

Fuel dispensing nozzle

A fuel dispensing nozzle is disclosed and includes a housing having a hollow main body portion and a handle portion with a hand-grip spaced from the main body portion, an elongate nozzle body mounted in the main body portion of the housing and having a fuel passageway extending longitudinally therethrough in a generally straight line devoid of any abrupt changes in direction, main valve means disposed in the fuel passageway for controlling the flow of fuel through the nozzle, manually operable valve actuating means, a spout for insertion into the fill opening of a vehicle fuel tank and having three integrally formed passageways therethrough comprising a fuel passageway, a vapor recovery passageway and a shut-off, venturi-vacuum passageway, a vapor recovery passageway through the main body and handle portions of the housing, a venturi-vacuum means for shutting off the flow of fuel through the nozzle when the vehicle fuel tank is full, attitude responsive means for preventing the opening of the main valve when the nozzle is not in the proper attitude for insertion of the spout into the fill opening of the vehicle fuel tank and attitude responsive valve means in the vapor recovery passageway in the housing for closing the vapor recovery passageway when the nozzle is not in position for insertion of the spout into the fill opening of the vehicle fuel tank. The housing and nozzle body are molded of a composite resin and the spout is extruded of a lightweight metal.
