A sound absorber includes an inner component and an outer component surrounding the inner component, the inner component defining an inner wall provided with apertures, and the outer component defining an outer wall extending along the inner wall. For improving the sound-absorbing properties as well as the flexibility of the sound absorber, the outer wall is implemented as a bellows which, together with the inner wall, defines individual cavities, the apertures of the inner wall opening into the cavities.

In a compressor, in particular for exhaust gas turbochargers, the compressor housing rear wall of the compressor housing enclosing the compressor wheel is mounted on a stator housing for mounting the drive shaft. The compressor housing rear wall is divided into a central disk and at least one outer ring, at least one vibration-damping and structure-borne sound-damping separating ring surrounding the central disk peripherally connecting the two adjoining housing wall portions together. Between the separating ring and the housing wall portions one or two metal bushings are inserted in which the housing wall is held frictionally and/or in form-locking manner.
