Abstract: An exhaust gas turbocharger has a flow-through exhaust gas guide section, a flow-through fresh air guide section and a bearing section arranged between the exhaust gas guide section and the fresh air guide section. It has a rotor assembly, comprising a turbine wheel which is rotatably accommodated in the exhaust gas guide section, a compressor wheel which is rotatably accommodated in the fresh air guide section, and a shaft which non-rotatably connects the compressor wheel with the turbine wheel, wherein the shaft is rotatably supported in the bearing section, and wherein a lubricant supply system with an inlet channel and an outlet channel is formed in the bearing section, via which lubricant may be supplied to the bearing elements of the bearing of the shaft, and wherein a lubricant-rejecting element is implemented. The lubricant-rejecting element comprises baffle elements for diverting a rotating proportion of the lubricant flow.

Abstract: In a heat shield for an exhaust gas turbocharger, by means of which at least a first area of the exhaust gas turbocharger is to be shielded against a second area in a heat insulating manner wherein the heat shield comprises at least one fastening structure by which the heat shield is attached to one of the housing parts of the exhaust gas turbocharger, the fastening structure is in the form of locking elements for interlocking the heat shield with the respective housing part. The invention also resides in an arrangement of a heat shield between two housing parts of an exhaust gas turbocharger in such a way that it is firmly attached to one housing part without contacting the other housing part.
