Abstract:
A fuel tank venting system for an automotive vehicle comprising: a fuel tank comprising a vapor dome, a refueling pipe, a fuel vapor trap that is connected to the fuel tank by an inlet conduit, wherein the inlet conduit is connected with the fuel tank through an orifice which is permanently open, the orifice being arranged in the vapor dome of the fuel tank in a static condition and a normally closed shutter device that communicates with the atmosphere and that is connected to the fuel vapor trap by an outlet conduit, the normally closed shutter device comprising an electrically-actuated valve being closed when the electrically-actuated valve is de-energized, wherein the normally closed shutter device is configured to be open during vehicle refueling process and to be closed when the fuel in the fuel tank reaches a predetermined fill level and when the vehicle is in normal operation.
