    摘要： 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.

    摘要： A vent apparatus is adapted to be coupled to a fuel tank and includes a valve housing made of a non-weldable plastics material and containing a valve. The vent apparatus further includes a tank mount made of a weldable plastics material and coupled to the valve housing. The tank mount is adapted to be welded to an underlying fuel tank to support the valve housing within a mounting aperture formed in the fuel tank. The tank mount is coupled to the valve housing by a retainer ring formed to include an annular channel opening toward the valve housing. The valve housing includes an annular upper flange extending into an upper region of the annular channel formed in the retainer ring. The tank mount includes an annular lower flange extending into a lower region of that annular channel to mate with the overlying annular upper flange and trap a flange seal therebetween.

    摘要： A vent apparatus is opened to allow free flow of fuel vapor from a vehicle fuel tank through the vent apparatus to a fuel vapor recovery canister during tank refueling until a predetermined level of liquid fuel is reached in the vent apparatus. Once refueling has been completed, the vent apparatus is closed to block or limit further flow of liquid fuel to the vent apparatus. At the same time, fuel vapor discharge passageways in the vent apparatus that had been closed once the fuel tank had been filled to a predetermined capacity with liquid fuel are reopened so that fuel vapor can flow freely from the fuel tank to the canister even though the volume or height of liquid fuel in the fuel tank has not decreased since the tank was filled during refueling.

    摘要： An apparatus is provided for controlling discharge of fuel vapor from an interior region of a vehicle fuel tank and preventing unsatisfactory liquid fill levels within the interior region of the vehicle fuel tank. The apparatus includes a housing adapted to be mounted in the vehicle fuel tank and formed to include a housing inlet, a vapor-inlet opening, and a passageway therebetween, a float valve disposed in the housing, and a skirt defining a channel around the float valve. Additionally a perforated baffle plate is coupled to the skirt and is formed to include a plurality of openings therethrough.

    摘要： 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. The diaphragm is attached to the float making it responsive to the rise and fall of liquid level in the tank. The diaphragm is generally concentrically peeled from a position overlying at least the vent or progressively opening and closing the vent.
