Abstract
A motor vehicle system device having a drive assembly, to which a charging device is assigned, has a compressor having at least one compressor runner supported using at least one bearing, the bearing having a stationary first bearing part and a second bearing part that is operatively connected to the compressor runner. An overpressure source is connected to the bearing, using which an overpressure is able to be produced in a bearing gap that is present between the first bearing part and the second bearing part. The overpressure source is the compressor and/or a part of a tandem pump, which besides the overpressure also makes available low air pressure for a user of the motor vehicle system device. The invention also relates to a method for operating a motor vehicle system device.
