ABSTRACT:
A flapper door is spring biased closed against a valve seat on the underside of a filler tube bulkhead having a refueling nozzle aperture. The valve seat has an annular tapered surface and a resilient annular seal on the flapper door contacts the valve seat in wiping engagement. A pneumatic dampener retards the speed of closure of the flapper door onto the valve seat.
