ABSTRACT:
A capless fuel filler neck has an annular resilient seal which seals over a fuel nozzle upon insertion in the filler tube. Further insertion of the nozzle opens a flapper biased against a rim flange on the lower end of annular seal. Movement of the flapper by the nozzle also moves an auxiliary seal on the flapper and which opens separate venting passages disposed externally of the nozzle tube. Upon removal of the nozzle from the filler tube, the flapper closes against the rim flange to seal the filler tube; and, the auxiliary seals close and seal the vent tubes. The vent tubes serve to prevent spray-back of fuel when the nozzle opens the flapper in a tank with pressurized vapor and fuel trapped in the filler tube and to provide an air inlet path to accommodate the aspiration of the refueling nozzle.
