ABSTRACT:
A fuel vapor recovery system wherein the physical installation and removal of the sealant member or gas cap is the activator of the system. The present invention offers a valve assembly which is mounted in the fuel filler tube and is positionally responsive to the presence or removal of the closure member assembly. The valve assembly of the present invention is disposed in combination with a vapor vent line leading to a fuel vapor canister. Broadly stated, the valve assembly includes first and second annular seals disposed on opposite sides of the vent port. The first seal blocks or prevents communication between the atmosphere and the fuel tank interior when the gas cap is removed. The second seal permits communication between the vapor vent and the fuel tank interior when the gas cap is removed from the open ended filler tube and blocks communication between the fuel tank's interior and the vent port when the cap assembly is reinstalled.
