摘要

Pneumatically damping bearing (10) comprises a working chamber (11) delimited by a bearing spring (12) having a wide flat cross-section and filled with a gas, and a nozzle channel connected to the working chamber. The ratio of the pump surface of the bearing spring to the cross-sectional surface of the nozzle channel is 2000-4500, preferably 3300. Preferred Features: The ratio of the length to the diameter of the nozzle channel is 0.5-10, preferably 1.3. The working chamber has a volume of 20-50, preferably 42 cm3>. The nozzle channel is arranged in a base plate (13).
