摘要： A check valve assembly is designed for insertion in an existing fuel tank filler tube having a mechanical nozzle seal and a vapor recirculation port. The insert has an integrally formed ground strap/tab for grounding a refueling nozzle and an attached flexible flapper positioned adjacent the recirculation port by an integrally formed spring tab. The insert has friction tabs for engaging the inner surface of the filler tube for retaining the check valve assembly in the filler tube.

摘要： A check valve for connection in a fuel tank filler tube. The valve has a tubular body with a plurality of radially inwardly extending projections on the inner surface of the tubular body or mounting adaptor. A valve seat is disposed downstream of the ribs, and an aperture is formed in the side of the tubular body. When the end of a siphoning hose is inserted into the check valve, the projections deflect the hose through the aperture to facilitate further insertion of the hose into the tank.

摘要： A fuel filler tube assembly including a one-way valve or check valve. The tube assembly is adaptable for pre-assembly on either a metal or plastic fuel tank and employs a common check valve with an adapter tube for plastic tanks. The valve employs a flapper with spaced ribs for deflecting a siphon hose away from the valve seal; and, the ribs are spaced to maintain the flow stream of he fuel during refueling and facilitating opening of the flapper.

摘要： A double shut-off refueling valve responds to a full fuel tank level by closing the recirculation line and the canister line. The valve includes at least one float having one or more sealing surfaces corresponding with the recirculation line and the canister line, respectively. The sealing surface is on the top of a float in the float valve. When the fuel in the tank reaches a full level, the float moves upward to close the recirculation line and the canister line substantially simultaneously. In one embodiment, the valve is a float valve having a coaxial seal where the two valve openings corresponding to the recirculation line and the canister line are arranged concentrically. In other embodiments, the sealing surfaces can be, for example, a ribbon seal, two separate sealing surfaces, or any other seal configuration that corresponds with the orientation of the recirculation line and the canister line within the fuel system.

摘要： A vent valve assembly at least partially disposed within an interior of a fuel tank is provided. The vent valve assembly comprises a housing, a first venting orifice, a float configured to close the first venting orifice when the level of fuel in the housing reaches a predetermined level, a second venting orifice, and a stop configured to close the second venting orifice to facilitate a pressure differential between the housing and the fuel tank.

摘要： A vapor emission control system includes an electrically operated shutoff valve in the fuel vapor vent recirculation line to the filler tube. The electrically operated valve is controlled by an electronic controller responsive to signals from a fuel level indicator and a fuel cap sensor in the tank. In one embodiment, the valve closes when the fuel level indicator indicates a full tank condition and when the fuel cap sensor indicates that the fuel cap is off the filler neck. The present invention thus provides a positive shutoff of fuel vapor to the filler tube during refueling.

摘要： A capless filler neck creates a vapor-tight closure for a fuel system using a spring-loaded door and a latch structure that anchors the door to create a vapor-tight seal. The filler neck includes a spring that biases the door shut and a wedge arrangement that acts as the latching structure. The wedge arrangement includes a movable plate that selectively engages with the door to pull the door shut with sufficient force to form and maintain the vapor-tight seal.

摘要： An onboard vapor recovery system for a vehicle fuel system having a fuel tank, a filler neck dynamically sealed by high pressure fuel flow from a filler nozzle, and a vapor recovery apparatus such as a carbon canister. The system includes a liquid level operated control valve which shuts off refueling with a two-stage closing operation providing an initial soft shutoff and a final shutoff. The system also preferably includes a valve in the fuel tank to maintain a predetermined pressure head sufficient to hold the system closed against further refueling at least temporarily, and a positive action, one-way check valve in the lower end of the filler pipe to prevent spitback of fuel from the pressurized tank once refueling has ceased.

摘要： A fuel tank vent valve disposed between the tank and a carbon canister to provide high volume venting between the tank and the canister under normal operating conditions. A diaphragm type control element within the valve pulls an internal valve plate against a seat when the filler pipe cap is removed thereby to close off the vent between the tank and the canister. The system operates with a filler pipe door seal of the type which is opened by the introduction of a filler nozzle. The vent valve is primarily constructed of molded plastic parts.
