The pneumatic spring (10) has 2 working chambers (12,18) of different diameter (14,20) and volume (16,22), each defined by 2 housing parts (24,26) and a rolling membrane (28,32), with a number of throttle openings (40) providing communication between the working chambers. A rolling surface (34) for one of the rolling membranes is provided by a central tube (38), a mirror-symmetrical rolling membrane (36) positioned between the second housing part and the latter rolling surface, for selaing the working chambers from one another. |
