  • Patent number: 6866058
    Abstract: A fuel tank vent apparatus comprises a housing. The housing comprises inner and outer sleeves providing a fuel vapor transfer passageway therebetween so that liquid fuel entrained in fuel vapor is shed therefrom as fuel vapor flows from a fuel vapor transfer port formed in the outer sleeve through the fuel vapor transfer passageway to a fuel vapor inlet port formed in the inner sleeve to produce a flow of demoisturized fuel vapor for discharge from the housing.

  • Patent number: 6796451
    Abstract: A cap for use on the threaded filler neck of a coolant reservoir, such as an automobile radiator, comprising a cover and main body and including: a means for transmitting torque from the cover to the main body to screw the cap onto the filler neck. The cap but for preventing excess torque from being transmitted. The cap includes a second torque transmission means for unscrewing the cap, which does not limit the torque that can be transmitted. The cap also includes a means for preventing the cap from being unscrewed when the coolant is under pressure; a pressure relief means to prevent the coolant pressure from exceeding a predetermined level; and a vacuum relief means for preventing the coolant pressure from falling below a second predetermined level.

  • Patent number: 6782911
    Abstract: A vent valve for use in controlling discharge of fuel vapor from a fuel tank. The vent valve includes a housing for attachment to the fuel tank includes a wall defining a cavity therein. The float is contained in the cavity of the housing and is responsive to the level of liquid in the fuel tank. The level in the fuel tank rises, the float rises within the housing. When the level of liquid in the fuel tank drops, the float moves downwardly in the housing. A passage is provided in the housing which communicates with an external portion of the tank. The vent valve includes at least one vent positioned proximate to and communicating with the passage for providing venting passage of vapor therethrough and to the passage. The vent valve includes a vent assembly having a flexible diaphragm which is displaceably positioned proximate to the passage to control the flow of vapor through the vent and through the passage.

  • Patent number: 6779544
    Abstract: A tank vent valve apparatus includes a valve housing formed to include an inlet port, an outlet port, and an interior region. The interior region is partitioned to define an intake chamber communicating with the inlet port, a discharge chamber communicating with the outlet port, and a float chamber containing a vent port valve and receiving liquid fuel and fuel vapor from the intake chamber. An interior wall defines a boundary between the float chamber and the discharge chamber and includes a valve seat formed to include a vent port therein. The vent port valve is buoyant and moves up and down along the interior wall as liquid fuel rises and falls in the float chamber to close and open the vent port.

  • Patent number: 6763966
    Abstract: A torque-limit signal cap for a filler neck includes a handle, a filler neck closure, and a torque-limit signaler. The torque-limit signaler operates during cap installation to interrupt temporarily a driving connection established between the handle and the closure to provide a tactile and/or auditory signal to a user turning the cap in the filler neck indicating that sufficient torque has been applied to the handle to seat the closure in a filler neck-closing position in the filler neck.

  • Patent number: 6755057
    Abstract: A filler neck closure assembly for a vehicle fuel tank filler neck includes a filler neck closure housing adapted to be coupled to the fuel tank filler neck. The filler neck closure housing is formed to include an outer aperture sized to receive a fuel-dispensing pump nozzle therein. The assembly also includes a dust shield mounted for movement relative to the filler neck closure housing to open and close the outer aperture of the filler neck closure housing. A lock of the assembly is coupled to the filler neck closure housing and is movable between a locked position to prevent the dust shield from opening the outer aperture and an unlocked position to allow the dust shield to open the outer aperture.

  • Patent number: 6701950
    Abstract: A vent apparatus is adapted for use with a fuel tank to control venting of fuel vapor from the fuel tank. The vent apparatus comprises a fuel vapor vent outlet to discharge fuel vapor from the fuel tank. The vent apparatus comprises a normally open first valve module to serve as a fuel fill limit valve and close when the liquid level in the tank reaches a predetermined fill limit and a normally open second valve module to serve as a fuel fill limit valve and close when the liquid level in the tank reaches the predetermined fill limit. The first valve module and the second valve module cooperate to block communication between the fuel tank and the fuel vapor vent outlet when the vent apparatus is positioned in a non-tilted orientation relative to a horizontal and the level of liquid fuel in the fuel tank reaches the predetermined fill limit to close both valve modules.
