Arrangement for limiting the fill level of a fuel tank

Arrangement for limiting the fill level in a fuel tank having a filler neck with a tank inlet end, said arrangement comprising:

• a valve flap having an off-center axis by which it is pivotably supported in said tank inlet end so as to be movable between a closing position in which the valve flap blocks fuel flow into said tank and an open position in which said valve flap is pivoted against the direction of fuel flow into said tank, a crank arm projecting from said valve flap into said tank, a coupling rod connected to said crank arm and including top and bottom stop members arranged on said coupling rod in spaced relationship, a hollow cylindrical float linearly movably disposed in a float guide tube and receiving said coupling rod so as to be movable relative thereto between said spaced stop members, said coupling rod with said stop members and said crank arm having together a weight, which is sufficient to hold said valve flap in an open position and said stop members being sufficiently spaced to permit movement of the valve flap into a closed position by inflowing fuel once such movement is initiated by an initial movement of the valve flap when said float is raised by a rising fuel level and lifts with it said top stop member and the associated coupling rod.
