Description

technical field

[0001] The invention relates to an integrated air supply unit, especially for an air spring system of a motor vehicle, said integrated air supply unit comprising an air compressor with a motor and an air dryer, wherein the air compressor is connected with the motor, the air The dryer and the pneumatic connections together form a functional unit. Background technique

[0002] An air spring arrangement for a vehicle is known from document DE 10 2005 030 726 A1, which comprises the necessary components of current air spring systems. The air spring device has a compressor, an air dryer, a pressure accumulator, as well as various valves and compressed air lines. In addition, the gas spring system has a pressure sensor and is controlled by a controller.

[0003] The main components of an air supply device for an air spring system according to the prior art include an air compressor, valves and a controller, which are usually installed in the vehicle in a manner d...
