Patent ID: 7347191

Claim:
A fuel system, comprising: a fuel tank having at least one opening into an interior of the fuel tank; an electrically operated vent valve having an inlet in communication with the interior of the fuel tank and an outlet through which fuel vapor is vented from the fuel tank, the vent valve being movable at least in part in response to an electric signal between an open position to allow fuel vapor to flow from the interior of the fuel tank through the outlet and a closed position to restrict fuel vapor flow through the outlet; a float that is movable in response to the movement of the vent valve between a position spaced from the outlet and a position at least substantially restricting fluid flow through the outlet; and a controller operably communicated with the vent valve to control application of an electric signal to the vent valve and thereby control at least in part the movement of the vent valve between its open and closed positions.
