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 combination fuel tank rollover valve, float actuated fill vent shutoff and tank vapor pressure relief valve assembly in a common housing for assembly into a single access opening in the tank. A header containing the pressure relief valve is sealed over the tank access opening and has an extension member attached to the undersurface of the header with an extension neck extending through the access opening. An interchangeable vent float valve subassembly is attached to the end of the neck before attachment of the extension to the header and assembly on the tank. Tanks of different depth can be accommodated simply by using extension members having a correspondingly different length necks, while the float valve subassembly and header are interchangeable.

摘要： A refueling fuel level responsive control valve with a two-stage closing operation providing an initial soft shutoff cue to the filler nozzle operator, and a subsequent final shutoff after a limited amount of "roundoff" filling to a maximum fuel level. The control valve includes two float-operated valve elements which close serially in response to initial shutoff and final shutoff refueling fuel levels. The initial shutoff partially closes the control valve to create a temporary shutoff-inducing increase in fuel tank pressure. Final shutoff occurs after allowing a few round-off "clicks" of the filler nozzle to fully close venting through the control valve.

摘要： A two-stage venting on-board refueling vapor recovery (ORVR) valve for controlling fuel tank venting to a storage canister during tank filling. A float actuated poppet has a small second stage venting hole therethrough. The poppet is mounted for relative movement with respect to a second stage vent valve member disposed on the float. During tank filling, venting is through a first stage relatively large flow area passage until rising fuel level causes the poppet to close the first stage vent flow area. Venting during continued filling is through the second stage venting hole in the poppet. After first stage valve closure relative movement or lost motion occurs between the first and second stage valve members. The poppet has an integrally molded annular resiliently flexible seal thereon which has a first stage annular sealing surface formed on one side of the poppet for sealing the first stage flow area, and a second stage annular sealing surface about the poppet hole on the opposite side of the poppet for sealing the second stage vent flow area and closing the vent passage.

摘要： A fuel level responsive vent valve assembly adaptable to a variety of different mounting requirements in a vehicle fuel tank. In general, the vent valve assembly comprises a standard, valve body, a top cover adapted to mate with the standard valve body at a vent outlet interface for a sealed vapor venting connection, and separately formed longitudinal connector means having a preassembly end for preassembly to a standard interface on the lower surface of the top cover, and an assembly end for longitudinally locking the standard valve body to the top cover. The standard assembly end of the longitudinal connectors can be varied in length to accommodate different valve height mounting requirements in different fuel tank applications. In a preferred embodiment the longitudinal connectors comprise metal pins or rods which can be pre-formed or cut to length to accommodate the standard valve body at different distances from the top cover. In addition to providing a longitudinal lock between the valve body and the top cover, the connector pins also provide an impact-resistant reinforcement to the sealed connection at the vent outlet interface.

摘要： An improved apparatus and method for calibrating a float-type vent valve for use in an automobile fuel tank. The valve is provided with a calibration plate in the lower end thereof below the float, the calibration plate defining an axially-adjustable support for the spring which balances the float. The calibration plate includes a force probe aperture through which a force measuring device of known type can be inserted to measure the downward force of the spring-balanced float at a specified distance from closure, preferably a near-closed position. The calibration plate then is adjusted up or down as needed until a position is determined where the spring-balanced float is properly calibrated, and then the calibration plate is permanently secured in place on the valve body so that the valve remains calibrated.
