Abstract

The invention relates to a ventilation device for fuel tanks, wherein the ventilation device comprises a compensator reservoir arranged in the interior of the fuel tank and at least two ventilation lines. The ventilation lines run from below the upper tank wall to the compensator reservoir and extend in the latter toward an opposite tank wall. The apparatus according to the invention is particularly well suited under all static and dynamic stresses for ventilating fuel tanks.
