Abstract
A filler neck includes a housing adapted to be coupled to a fuel-delivery conduit coupled to a fuel tank inlet of a vehicle fuel tank. The housing includes a passageway that defines an axis of the filler neck and is adapted to receive a pump nozzle. The filler neck further includes a shuttle positioned for movement in the passageway along the axis between a closed position to close the passageway and an opened position to open the passageway in response to engagement with the pump nozzle
Claims19
A filler neck for use with a fuel-delivery conduit defining an axis disposed transversely to an axis of the filler neck and adapted to be coupled to a vehicle fuel tank, the filler neck comprising
- a housing adapted to be coupled to the fuel-delivery conduit, the housing including a passageway that defines the axis of the filler neck and is adapted to receive a pump nozzle, and
- a shuttle positioned for movement in the passageway along the axis of the filler neck between a closed position to close the passageway and an opened position to open the passageway in response to engagement with the pump nozzle, the shuttle including a side wall and a guide surface, the side wall defining an outlet aperture adapted for communication with the fuel-delivery conduit when the shuttle is positioned in the opened position, the guide surface being positioned to direct liquid fuel dispensed by the pump nozzle through the outlet aperture into the fuel-delivery conduit when the shuttle is positioned in the opened position.
A filler neck for use with a fuel-delivery conduit adapted to be coupled to a vehicle fuel tank, the filler neck comprising
- a housing adapted to be coupled to the fuel-delivery conduit, the housing including a passageway that defines an axis and is adapted to receive a pump nozzle, and
- a shuttle positioned for movement in the passageway along the axis between a closed position to close the passageway and an opened position to open the passageway in response to engagement with the pump nozzle, the shuttle including a side wall, the side wall including a first half and a second half which are defined by a first plane on which the axis lies, the first half defining an outlet aperture through which liquid fuel dispensed by the pump nozzle flows into the fuel-delivery conduit in a direction transverse to the axis when the shuttle is positioned in the opened position, the second half being apertureless so that liquid fuel dispensed by the fuel pump flows through the outlet aperture.
A filler neck of a fuel system including a vehicle fuel tank, a fuel-delivery conduit coupled to a vehicle fuel tank, and a fuel vapor re-circulation conduit coupled to the vehicle fuel tank, the filler neck comprising
- a housing defining a nozzle-receiving chamber adapted to receive a pump nozzle, a mixing chamber, and an aperture positioned in communication with the nozzle-receiving chamber and the mixing chamber, the housing being adapted to position the mixing chamber in communication with the fuel-delivery conduit and the fuel vapor re-circulation conduit, and
- a shuttle positioned for movement in the aperture between a closed position to close the aperture and an opened position to open the aperture in response to engagement with the pump nozzle, the shuttle defining an outlet aperture positioned in the nozzle-receiving chamber when the shuttle is positioned in the closed position, the outlet aperture being positioned in the mixing chamber when the shuttle is positioned in the opened position so that liquid fuel dispensed by the pump nozzle can flow through the outlet aperture into the mixing chamber to mix with fuel vapor from the fuel vapor re-circulation conduit to provide a mixture of liquid fuel and fuel vapor for delivery through the fuel-delivery conduit to the vehicle fuel tank.
