<p>The compressor of an exhaust gas turbocharger comprises a compressor wheel (14), an outer compressor housing (101), and a housing insert (102, 103) arranged radially outside of the compressor wheel (14), wherein the housing insert has an insert wall contour, which together with a hub of the compressor wheel (1) delimits a flow channel, and the housing insert (10) is fastened to the outer compressor housing (20) in the axial direction. According to the invention, the housing insert piece comprises an absorption element in the form of a circumferential bellows (105) for securing (106, 109) to the outer compressor housing (101) in order to transfer axial forces from the insert wall contour (11). The kinetic energy released during failure is absorbed by the elastic and plastic deformation bellows-shaped absorption element. The claimed absorption element thus requires the smallest possible installation space for high axial unloading of the housing connection between the inner and outer compressor housing parts and/or between the compressor housing and the bearing housing in the event that the compressor wheel bursts.</p> |
