Abstract: A fuel tank with a venting system includes a flap for closing and opening a vent made in the tank. The flap is coupled to a float. The flap includes a valve coupled to a second float mounted in a hinged manner in the tank so that the valve adopts a closed position, being pushed by the second float when the level of fuel in the tank reaches a certain threshold, and an open venting position in order to prevent overpressure within the tank, being driven by the second float when the level of fuel is below the threshold and the force exerted by the internal pressure on the valve is less than the sum of the forces exerted on the valve by the atmospheric pressure and by the weight of the second float.

Abstract: The invention relates to a tank for receiving fuel, said tank comprising a venting system comprising a flap for closing an opening made in the tank, said flap being subjected to a float and mounted in a hinged manner in the tank so as to adopt a closed position, pushed by the float when the level of fuel in the tank reaches a certain threshold, and an open, venting position, driven by the float when the level of fuel is below said threshold. According to the invention, the flap comprises a valve controlled by means that can open the valve when the flap is in a closed position and the level of fuel is below said threshold.
