Abstract
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.
Claims5
A filler neck (1) for the fuel tank of a motor vehicle, comprising a funnel-type insert and, adjoining the latter in an inward direction, a flap with a locking element which, when the filler tube of a gas-pump nozzle is inserted, is moved so as to release the flap, the flap (16;
- 116) is rotated about a hinge pin (14;
- 114), which is displaced in space, and is retained by at least two elements (11, 21;
- 111, 121) which are each pivoted about a pin (10;
- 110) and only release the flap (16;
- 116) when the two elements (11, 21;
- 111;
- 121) are pivoted to one side, counter to the force of a spring (12, 22;
- 112, 122) , by the inserted filler tube (30).
