Abstract
The invention is directed to a level control arrangement for a vehicle having air springs (8) via which the vehicle is suspended relative to at least one vehicle axle. Directional valve (18) conducts moist air and is configured as a pneumatically controllable valve in order to prevent icing thereof. For controlling or switching, directional valve (18) is charged via the control line (22) with pressurized air generated by the compressor (4). The control line (22) can be connected via a third directional valve (20) to the atmosphere so that, when the compressor (4) is not running, the second directional valve (18) can transfer from a switching state wherein the compressor (4) is connected to the air dryer (6) into an other switching state wherein the air dryer (6) is connected to the atmosphere.
