Abstract
In the case of a longitudinally adjustable gas spring with two tubes enclosing each other concentrically and with a valve at one end and with a relief channel at the end where the piston rod exits the inner tube consists of plastics material. It has groove-like channels on its external wall which connect the relief channel with the valve. The webs between adjacent channels bear against the internal wall of the outer tube. The result is a cost-saving structure of the inner tube, which at the same time becomes very stable and is easy to manufacture.
