Abstract:
A method of producing a vane damper comprising a casing 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 casing 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 the associated bearing member by extruding aluminum or aluminum-containing alloy; providing the vane with sealing members for establishing a seal against surfaces of the space and of the bearing member; making two bilaterally symmetrical tubular halves of the casing by extruding aluminum or aluminum-containing alloy; cutting the extruded products forming the casing halves, vane, and bearing member to remove excess material; and attaching the two halves to form the casing enclosing the vane damper.
