Filling limitation device for a fuel tank and automotive vehicle equipped with such a device.

摘要

An expansion volume (14) which is connected to the outside by an aeration circuit (15) is arranged in the upper section of the reservoir (1). This circuit comprises a housing (20) inside which a ball (22) rests freely on the concave upper surface of a support (21). Opening of the flap (11) leads to rotation of the support (27): The magnet (26) comes into contact with the housing (20) and the ball (22) moves laterally. The effect of this movement is to raise the bell-shaped part (23) and this seals the outlet aperture provided in the upper section of the housing (20). Application to motor vehicles. <IMAGE>
