VENTILATED AIR BELLOWS FOR A PNEUMATIC SPRING PNEUMATIC SPRING CONTAINING A VENTILATED AIR BELLOWS AND PNEUMATIC SPRING SYSTEM CONTAINING VENTILATED AIR BELLOWS

摘要

The invention relates to an air bellows (14) for a pneumatic spring (10) in particular of a commercial vehicle comprising an axle side region (18) and a body side region (16) wherein the axle side region (18) can be arranged in a plunger (50) and moved by means of a compression or extension movement between a first compressed position and a second extended position and further comprising an interior space (11) which can be filled with compressed air via a compressed air opening (12) that is connected to a compressed air line (13). The air bellows (14) further comprises a valve (20) connected to the atmosphere for ventilating the interior space (11) wherein by applying compressed air present in the interior space (11) to the valve said valve can be moved into the closed position.
