Abstract
A method for venting of a liquid tank with a valve, a primary compartment and a secondary compartment which are connected together via a bridge. The valve includes a chamber provided with a cover, which extends at least partly into the tank and is connected via an upper venting aperture to a venting circuit. A first device monitors a level of liquid in the primary compartment. A second device monitors a level of liquid in the secondary compartment. The valve configured to be closed when the first device detects that the level of liquid in the primary compartment is equal to or higher than a first predetermined filling level, and the second device detects that the level of liquid in the secondary compartment is equal to or higher than a second predetermined filling level.
