ABSTRACT:
An onboard refueling vapor recovery (ORVR) system for a vehicle fuel system having a fuel tank, a mechanically sealed filler neck which receives a filler nozzle, and a vapor recovery apparatus such as a carbon canister. The system includes a nozzle shutoff line connecting the fuel tank with the filler neck to trigger the automatic shutoff mechanism of the filler nozzle when the level of fuel in the tank reaches a predetermined level. The system also includes a liquid-responsive control valve permitting venting of fuel vapor from the tank during both refueling and normal vehicle operating states when the fuel level in the tank is at or below the full level established by the nozzle shutoff line.
