ABSTRACT:
A fuel tank system includes a fuel tank, a fuel filler pipe connected to the fuel tank, a shutter assembly disposed in the fuel filler pipe, the shutter assembly being openable by a refueling nozzle to be inserted into the fuel filler pipe, a guide disposed in the fuel filler pipe for guiding the inserted refueling nozzle toward the shutter assembly, an engagement member disposed in the fuel filler pipe and angularly movable through a constant angle by being engaged by the refueling nozzle inserted in the fuel filler pipe and guided to the shutter assembly, and a fuel vapor venting mechanism including an on-off valve responsive to the angular movement of the engagement member for providing fluid communication between the fuel tank and an associated mechanism such as a canister. The engagement member is positioned between the guide and the shutter assembly. The on-off valve is slidable on a cylindrical surface which has a plurality of raised stripes or ridges extending axially for allowing the on-off valve to slide smoothly and also for permitting fuel vapors to flow in a large amount when the on-off valve is opened.
