  "textContent": "Pneumatic spring arrangement (1) for a vehicle comprises a first and a second pneumatic spring (2, 3) arranged in parallel. Each pneumatic spring consists of a bellows (4, 5) made of elastomer material and provided especially with an embedded strength support. The bellows form a tube (10, 11) surrounding an air chamber (12, 13). Each pneumatic spring also consists of a cover (6, 7) with a connecting region for the end of the bellows, and a roller piston (8, 9) with a connecting region for the other end of the bellows and a free rolling surface for the tube. The air chamber (13) of the second pneumatic spring (3) with a second inner pressure (p2) is arranged within the air chamber (12) of the first pneumatic spring (2) with a first inner pressure (p1). The two air chambers communicate via an overflow line (14) and a pressure system so that the second inner pressure is greater than the first inner pressure. Preferred Features: The pressure system is a compressor (15) integrated in the overflow line. The compressor is combined with a valve block (27).",
