Abstract

Gas spring includes a cover which works together with a rolling bellows and a bottom part to form a gas-filled spring space, where at least part of the outside surface of the rolling bellows is covered by a sleeve. The sleeve provides a receptacle for at least one sensor which detects the stroke position of the gas spring.
