Filler tube for the fuel tank of a motor vehicle with selective opening

摘要

A filler neck for the fuel tank of a motor vehicle, comprising a flap and a locking element. The filler neck is designed such that it is impossible to fill the tank with the wrong fuel. The foregoing is achieved by the fact that the flap can be rotated about a hinge pin which is three-dimensionally movable and while the flap is retained by at least two elements that are pivotable about one respective pin. One of the pivotable elements supports the hinge pin of the flap while another pivotable element is configured as a locking lever that is disposed across from the hinge pin.
