Abstract: The present disclosure refers to a fuel tank for a vehicle equipped with a valve housing and a ventilation opening that has a ventilation valve placed on an upper opening of the tank and which projects into the tank interior. Additionally, the wall of the valve housing is interspersed with at least one wall opening, and a float has been arranged in the valve housing that can be moved from a resting to a closing position and has a sealing element on its upper end. The float is in a lower place in the valve housing when it is in its resting position and the sealing element releases the ventilation opening. The float, when in a closing position, closes the ventilation opening with its sealing element as soon as the closing level is reached.

Abstract: 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.
