  • Patent number: 7543597
    Abstract: A vent valve assembly utilizes a lever arrangement that opens a vapor discharge opening such as during normal operation of a motor vehicle to permit fuel vapor venting and that seals the vapor discharge opening such as when the motor vehicle is inclined to prevent liquid fuel from discharging through the vapor discharge opening.

  • Patent number: 6918405
    Abstract: A valve assembly for attachment in an aperture of a fuel tank wall includes a cap member with a nozzle, a carrier stage, a float stage, and a float housing. The carrier stage has a carrier carrying a sealing element with a relatively larger orifice opposing a relatively smaller orifice. The float stage includes a pivot pin and a float defining a stem. The pivot pin is movably located on the stem with the sealing element located apart from the float. The float contacts a portion of the sealing element during a refilling condition, and the sealing element seals the nozzle to prevent overfilling the fuel tank. The orifices permit the valve assembly to reopen in stages.

  • Patent number: 6648016
    Abstract: A valve assembly for admitting a tube or fuel into a vehicle fuel tank is disclosed. The valve assembly has a fixed housing with an inlet, an outlet, a middle section and an inner surface with an opening. At least one projection depends from the inner surface between the inlet and the outlet. The projection deflects the tube toward and through the opening. A piston element, which is slidably mounted to the housing, is normally urged in a direction to close the outlet and the opening until the tube or fuel urges the piston element in an opposite direction.
