Abstract:
A level control for vehicles has at least one air spring cushioning a vehicle body relative to a vehicle axle. A compressed air generator is connected to the air spring by an air dryer and to the atmosphere by a check valve opening in the intake direction of the generator. The air spring can be connected to the atmosphere for discharge via a pneumatically controllable first directional valve. The air spring pressure is applied to a pneumatic control input of the first directional valve via a second controllable directional valve. The input of the first directional valve can be connected to the atmosphere for ending discharge of the spring. A line with a compressed air accumulator branches off from the air spring supply line via a first changeover valve. The accumulator is connected to the intake side of the generator via a second changeover valve.
