Numerous cavities exist in a turbocharger for reasons of construction. If such cavities are filled with particles, inexpensive particle vibration dampers can be realized. Moreover, advantages with regard to additional containment security result in the case of possible bursting of the compressor wheel, and also with regard to noise suppression.
