Patent ID: 6846167

Claim:
An exhaust gas turbocharger ( 1 ) having a housing and having a shaft ( 2 ) which is arranged so as to be capable of rotating about its longitudinal axis in the housing and on which a turbine wheel ( 4 ) and a compressor wheel ( 3 ) are seated and which is guided in radial bearings ( 5 , 6 ) and in at least one axial bearing ( 9 ), the radial bearings ( 5 , 6 ) being passive permanent-magnetic bearings which each have a bearing plate ( 12 , 16 ) which is seated, as a rotor, on the shaft ( 2 ), and at least one stator ( 19 , 20 , 21 , 22 ) which is disposed axially opposite to said rotor, wherein a resilient element ( 60 , 61 ) is arranged between each stator ( 19 , 20 , 21 , 22 ) and a part ( 37 , 38 ) which is fixed to the housing in order to radially damp oscillation movements of the shaft ( 2 ).
