<p>A positive sealing inlet (PSI) valve assembly is provided for an automotive fuel tank fill tube. The PSI valve assembly includes a tubular housing having an interior and an exterior and this housing is fluidly mounted in series with the fuel tank fill tube. The housing includes a wall extending across the interior of the housing adjacent one end and this wall includes a through opening. A flapper valve is movable between an open and a closed position. In its closed position, the flapper valve overlies and closes the wall opening. Conversely, in its open position, the flapper valve is positioned away from the wall opening to permit nozzle insertion through the wall opening. The PSI valve is pivotally connected to a valve holder and this valve holder is mounted entirely within the interior of the housing. A spring is operatively disposed between the valve holder and flapper valve and urges the vent valve towards its closed position.</p> |
