ABSTRACT:
A system for controlling the release of fuel vapors and liquid fuel from a vehicle fuel tank is provided. The system includes: (1) a cap-controlled valve assembly which conducts fuel vapors to an on-board vapor capture device and which opens when the tank's fuel filler cap is removed or when the pressure in the fuel tank exceeds a predetermined value and which closes when the filler cap is replaced; (2) a first, normally-closed, flapper door and a flapper-door/fuel-nozzle seal, both of which are located in the region of the the mouth of the vehicle's filler pipe, above the level at which fuel vapors pass into the cap-controlled valve assembly; (3) a second, normally-closed, flapper door and a flapper-door seal, both of which are located below the level at which fuel vapors pass into the cap-controlled valve assembly; and (4) a vent conduit which connects the fuel tank to the filler pipe assembly at a level between the first and second flapper doors. The system prevents liquid fuel from being expelled from the vehicle's filler pipe upon removal of the filler cap and at the same time provides reliable venting of the fuel tank during normal operation and reliable shut-off of service station fuel pumps during refueling.
