Abstract

A damping element, particularly for a vehicle, includes first and second cylinder chambers, a cylinder and a connection element formed as a hollow body fastened to the end of the cylinder. A movable separating piston is arranged between the second cylinder chamber and the interior of the connection element for separating the region of the second cylinder chamber that is filled with hydraulic medium from a region of the connection element that is filled with a compressible medium. The connection element has a tube cross section having an outer diameter corresponding to the inner diameter of the cylinder and is inserted into the cylinder and tightly and fixedly. The separating piston is arranged so as to be coaxially displaceable in the cylinder and its displaceability is limited relative to the end region of the cylinder by the front side of the end region of the connection element.
