<p>The invention relates to an expansion tank (1) intended to be part of a cooling system of a motor vehicle and comprising a casing (2) which encloses an expansion chamber (3). A dividing wall (16) divides the expansion chamber into an upper space (3a) and a lower space (3b), with an inlet aperture (7) situated in the upper space and an outlet aperture (5) in the lower space. The upper side of the dividing wall constitutes a downward-curving guide path (20) which guides a flow of coolant from the upper space to the lower space. A inlet basin (25) is provided in the upper space, the upper end of the guide path serves as an upper edge (26) of the inlet basin, and the inlet aperture leads into the inlet basin at a level below said upper edge so that the coolant which flows into the expansion chamber via the inlet aperture is caused to rise in the inlet basin and thereafter reach the guide path via said upper edge.</p> |
