The invention relates to a level control arrangement for vehicles with at least one air spring by which a vehicle body is cushioned with regard to at least one vehicle axle, having the following characteristics: a compressed air generator, which can be connected to the air spring by means of an air dryer, the compressed air generator can be connected to the atmosphere by a check valve, which opens in the intake direction of the compressed air generator, the air spring, which can be connected to the atmosphere for discharge purposes via the air dryer or a pneumatically controllable directional valve, wherein the pressure of the air spring is applied to a pneumatic control input of the first directional valve via a second controllable directional valve against the force of a reset force that acts on the pneumatic control input, the pneumatic control input of the first directional valve can be connected to the atmosphere, for the purpose of ending a discharge process of the spring, a line with a compressed air accumulator branches off from the supply line of the air spring via a first changeover valve, wherein the compressed air accumulator is connected to the intake side of the compressed air generator via a second changeover valve and a line that is connected to the compressed air path between the check valve and the compressed air generator, and wherein preferably a pneumatically operating pressure controller is contained in this line. |
