- the quantity of liquid contained in the first reservoir 35 is thus distributed in several compartments, which makes it possible to better distribute its mass and to limit the movements of liquid capable of generating noise when it abuts on the side walls 37d of the first reservoir 35. This also makes it possible to avoid the formation of an unbalance due to the displacement of too much liquid during the movement of the vehicle (in particular during cornering, braking, acceleration, etc.).
- the partitions can be of varied shape. They can be reported and fixed on one of the lower walls 37b or 37a, the first tank 35 or be distributed on both. Alternatively, the partitions can be formed integrally with one of the walls 37a, 37b or distributed and formed integrally with the two walls 37a, 37b.
