Abstract (en)

[origin: WO2009000436A2] The invention relates to an exhaust gas turbocharger for an internal combustion engine, comprising an exhaust gas ducting section (2), arranged in an exhaust line of the internal combustion engine and a turbine rotor (4), rotatably housed in a rotor chamber (10) in the exhaust gas ducting section (2) through which exhaust gas coming from the internal combustion engine may flow. The flow around the turbine rotor (4) may be altered by means of a guide apparatus (12) and the guide apparatus (12) comprises a bearing ring (13)with rotatably mounted guide vanes (14) and a contour sleeve (15), wherein a first separation (A) between the bearing ring (13) and the contour sleeve (15) is fixed by providing at least one spacer element (16) with a longitudinal axis (17), an outer surface(18) and a cross-sectional area (19). According to the invention, the outer surface (18) has a second separation (MA) from the longitudinal axis (17) which may be altered by means of the cross-sectional area (19) and/or a length (L) for the spacer element (16). The invention is of application in automobiles and commercial vehicles.
