Abstract
A fuel tank for vehicles has a filler tube and a filling level limiting device, with the filler tube comprising, in the interior of the fuel tank, a closing device which interacts with an actuating device which is composed of: a) a frame which is fastened in the interior of the fuel tank and which has a force store which actuates the closing device; b) a locking arrangement which holds the force store in the stressed state; c) a release mechanism which is operatively connected to a float; and d) a stressing mechanism for stressing the force store. The actuating device ensures that a flap closes precisely when a nominal filling level is reached, and does not open again even under intense fluctuation of the liquid level.
Claims9
A fuel tank for vehicles comprising a filler tube having a portion located within the tank, a filling level limiting device located within the tank, a closing device comprising a flap valve for the filler tube which interacts with an actuating device, the actuating device comprising:
- a) a frame fastened in the interior of the fuel tank and a force store located in the frame for urging the closing device to a closed position;
- b) a locking arrangement guided in the frame which holds the force store in a stressed state when the closing device is in an open position;
- c) a release mechanism operatively connected to a float for releasing the locking arrangement and the force store for urging the closing device to the closed position;
- and
- d) a stressing mechanism for stressing the force store for moving the closing device between a closed position and an open position;
- and
- e) the force store comprises a spring element, the spring element comprises a pressure spring which is supported with one end in the frame and the other end on a piston, the piston is guided in the frame and is mechanically connected to the closing device, wherein the locking arrangement engages the piston.
A fuel tank for vehicles comprising a filler tube having a portion located within the tank, a filling level limiting device located within the tank, a closing device for the filler tube which interacts with an actuating device, the actuating device comprising:

- b) a locking arrangement which holds the force store in a stressed state, the locking arrangement comprises a bar which is movable transversely with respect to a movement direction of the piston, in opposition to the force of a further spring, wherein an arm, which is pivotable on the frame, is attached to a float, the arm is movable to pull the bar outward for releasing the piston when a nominal filling level is reached in the tank;
- c) a release mechanism operatively connected to the float;
- and
- d) a stressing mechanism for stressing the force store for moving the closing device between an open position and a close position.
