摘要： The invention relates to a pressure compensation element which can especially be fastened to a vent dome (13) and comprises a pot-shaped cover element (1) having a floor surface (3) and a wall (4), an adapter (2), inserted into the cover element (1) and having a through bore (5) the opening of which is covered by a filter element (14), and an air passage (7) that is configured between the inner wall of the cover element (1) and the outer wall of the adapter (2) and between the floor surface (3) of the cover element (1) and the bore (5) of the adapter (2). The invention is characterized in that the adapter (2) has an asymmetric outer contour that is discontinuous along its periphery.
