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 are variable because of the rotatability of the vane. The vane is mounted in the body by a bearing member and operates in a working medium that is located in the space. The working medium is transferable between the variable spaces via a passage or at least one throttle function to produce damping. The method includes producing the vane with associated bearing member by extruding aluminum or aluminum-containing alloy. The extruded product is cut for production of the respective vane with associated bearing member. The vane is provided with sealing members for establishing a seal against surfaces of the space and of the bearing member.
