Abstract
A vane damper, and a method for making the vane damper is disclosed. A casing including a space for at least one rotable vane divides the space into two parts. The spaces are variable because of the vane which rotates within the space. Further, a number of asymmetrical ducts connects the spaces separated by the vane with a gas accumulator space so that a medium within the spaces for damping motion of the vane can expand into the gas accumulator space against the force of a gas. The vane is produced by extruding aluminum or an aluminum containing alloy. The vane is sealed against the surfaces of the space as well as a bearing member supporting the vane.
