Abstract

The invention relates to a hydraulic wing damper (1) designed for use on a two or four-wheeled vehicle. The wing damper comprises an outer housing (2) consisting of an upper lid (2a) and a lower housing part (2b), which together enclose a damping-medium-filled main chamber (3) divided by a demarcating wing (4) into two chambers (3a, 3b), each with its own working volume. The wing (4) is rotatable about a first wing end (4a) and the outer face (4a') of the wing end rotates in a custom-made cutout (2c) in the lower housing part (2b). In the first wing end (4a) there is fixed a first end of a lever (4b), the lever (4b) rotates with the wing (4) about the first lever end in relation to said outer housing (2). Connected to the main chamber (3) there is arranged a pressurized space (6) having a certain volume, designed to be used to compensate for the change in volume of the damping medium due to a change in temperature of the medium. In order to minimize the risk of cavitation, the space for pressure compensation is arranged directly connected to the cutout (2c) in the housing part (2b), in which cutout the outer face (4a1) of the first wing end rotates, so that a connection can be made to the volumes of both chambers (3a, 3b).
