Beschreibung
Zusammenfassung:	A longitudinally controllable adjustment device, in particular a gas spring partially filled with a fluid, has a piston disposed on a piston rod and a valve, inside of which a valve body is slidable in its longitudinal direction. It has a tapered section by which a seal, abutting on a sealing face, can be bridged. In order to make possible a long-stroke embodiment and a short-stroke embodiment, the seal has two sealing beads, of which the one sealing bead sealingly abuts in all embodiments against a truncated cone-like sealing face of the valve body, while the other sealing bead, if required, abuts on an optionally provided additional cylindrical sealing face between the truncated cone-like sealing face and the tapered section.
