  "textContent": "A support ring (8) is located between the rolling piston (4) and the tubular casing (6) for the damper part (1), so that the piston is supported against and centred by the casing. The damping device comprises a damper part and an air spring. The damper part comprises a tubular casing, a fastener part (20) and a piston rod (9). The air spring comprises a spring bag (3), an outer tube (2) and a rolling piston supporting a rolling profile (5). The spring bag defines a gas volume (10) containing a gas under pressure when the rolling piston seals this volume from the tubular casing and is fixed on top of the latter.",
