An apparatus for preventing the creation of an underpressure in the air-suspension bellows of vehicles comprises a pneumatic control device (12) for the air supply to the air-suspension bellows (16,18) and a duct system (14,20,24) between the control device and the air-suspension bellows. A non-return valve (26) is incorporated into the duct system (14,20,24) and is arranged in such a way that when a predetermined value of underpressure is exceeded in the duct system ambient air enters the duct system through the non-return valve. <MATH> |
