Valve for venting a fuel tank

It is proposed a valve (200) comprising: - a chamber (201) adapted to extend at least partly into a tank (100) and adapted to be connected via an upper venting aperture (203) to a venting circuit; and - a shut-off point defining a single maximum filling level within the tank (100), located away from said chamber (201), said shut-off point being in fluid communication with the chamber (201).
