Abstract:
A method of producing a vane damper comprising a body including a space for at least one rotatable vane that divides the space into two part spaces that are located on either side of the vane, the spaces being variable because of the rotatability of the vane, the vane being mounted in the body by a bearing member and operating in a working medium that is located in the space, the working medium being transferable between the variable spaces via a passage or at least one throttle function to produce damping, the method comprising:producing the vane with associated bearing member by extruding aluminum or aluminum-containing alloy;cutting the extruded product for production of the respective vane with associated bearing member;providing the vane with sealing members for establishing a seal against surfaces of the space and of the bearing member; andmachining portions of the surfaces of the body that interact with movable surfaces on the vane, the machining providing sealing against the movable surfaces on the vane by means of the sealing members.
