Abstract

See full text

A vehicle air suspension installation includes pneumatics configured for operation in conjunction with a compressed air supply installation, and comprises: a pneumatic line having a port connection to the air supply installation, air bellows, each serving as a pressure chamber for an air spring, one air bellows being connected to the pneumatic line via a directional solenoid valve, and the air bellows being fillable/bleedable depending on a switching state of the valve, and first and second directional valves forming a solenoid valve system, which has a pneumatic part that is actuatable by a magnetic part. The first directional valve forms a primary valve, and the second forms a secondary valve. First and second air bellows associated with the valve system are fillable/bleedable depending on the switching state of the primary and secondary valves. The primary and secondary valves are controllable by a controller of the magnetic part. The controller is common to and acts upon both valves.
