The invention refers to a filler neck for the fuel tank of a vehicle that encompasses a refueling channel (), a first opening () and below it, arranged in a transversal wall (), a second opening () that can be closed by a closing device. In a longitudinal section () of the refueling tank () that extends between the transversal wall () and the first opening (), ends a drainage channel () via a drainage opening (). In addition, a closing element () has been arranged in the longitudinal section (), movable between a position that closes the drainage opening () and one position that releases it.

Filler neck for the fuel tank of a vehicle

The device includes a protective mechanism for preventing introduction of a gasoline-type nozzle into an inlet passageway of a fuel tank of a Diesel motor vehicle, the inlet passageway defining a central axis, the protective mechanism comprising two arms mounted at least partially within the inlet passageway, the arms being pivotable around a pivot axis substantially parallel to the central axis. A connector is mounted at least partially within the inlet passageway, the connector being movable in a plane transverse to the central axis, movement of the connector outwardly from an idle position relative to the central axis causing the arms to pivot from an idle position toward a free-flow position. The connector is configured so that insertion of a gasoline-type nozzle into the inlet passageway will not move the arms to the free-flow position, whereas insertion of a Diesel-type nozzle into the inlet passageway will move the arms to the free-flow position.
