Filling device (100, 200, 300, 400, 500) for fluid tank (10) comprising a filling pipe (102, 402, 502), a fïrst stopper © ( 110, 210, 420, 510) to prevent the overfilling of the tank, and a second stopper (120, 220, 320, 420, 520) for preventing unwanted o discharge of fluid from the tank; a first float (110, 2 10, 4 10, 510) mechanically connected to the first stopper so that the first float, by positioning itself in a predetermined position, closes the first stopper; and a System (122, 222, 422) for retaining the second stopper which, when fluid leaves the tank, closes the second stopper and, when the fluid enters the tank, opens the second stopper. The retai - o ning system constantly urges the second stopper because when the device is in a position under the effect of the weight of a heavy élément (430, 520), the retaining system tends constantly to keep the second stopper (420, 520) in its closed position. |
