Abstract

An air compressor, from whose outlet a supply line leads to an air drier for the purpose of supplying the compressed air system. On the outlet side of the air drier, the supply line branches into a plurality of line branches that lead to at least two consumer circuits. The pressure in the consumer circuits can be monitored by pressure sensors. Furthermore, control electronics are provided which are connected to the pressure sensors. The consumer circuits can be disconnected from the compressed air supply by a closing member that is disposed in the respective supply line branch and can be switched by the programmable control electronics. By means of this, the supply of compressed air into the consumer circuits and the withdrawal of compressed air for transfer from one circuit into the others can be controlled by the control electronics. The compressed air supply device can be used in the vehicle compressed air systems of commercial vehicles.
