A turbocharger for an internal combustion engine, comprises a housing (2) with a compressor blade (3) on the air side, a shaft (1) driving the compressor blade (3), and at least one radially acting rotary bearing (5) for mounting the shaft (3), wherein the rotary bearing (5) is designed as a hydrodynamic sliding bearing, wherein a stationary bearing element (6) is penetrated by the shaft (1) and a first mounting is formed on one first side of the bearing element (6) and acts axially against a bearing collar (7) rotating with the shaft, wherein an oil supply (9) for supplying the mountings is designed in the bearing element (6), wherein a plurality of flow surfaces (10) with a height (h) varying in the circumferential direction is formed on one surface of the bearing element (6) facing the bearing collar (7) in the axial direction, wherein an individually dimensioned throttle element (11, 12) is designed in the oil supply (9) for each of the two mountings.

Turbocharger for an internal combustion engine

A housing for a turbocharger forms a housing jacket () which surrounds a rotor space () for receiving a turbine rotor (). The housing jacket consists of sheet metal at least in part. A connection pipe (') provides for communication with an exhaust gas manifold () of a combustion motor (). To reduce heat losses, it is not only the housing jacket () which surrounds the rotor space () and consists of sheet metal, but at least the connection pipe (&#x2032;) for communication with the exhaust gas manifold () is shaped of sheet metal and is in heat conductive connection with the sheet metal of the housing jacket ().

Housing for a turbocharger

A casing assembly for a turbocharger of an internal combustion engine includes a rotor casing having an intake duct and an exhaust flow passage which is connected to an exhaust flange and constructed for attachment to the rotor casing such as to allow a relative movement between the exhaust flow passage and the rotor casing. In this way, a sliding fit is provided which prevents thermal stress in the system rotor casing and exhaust flow passage. An outer housing surrounds the exhaust flow passage, rotor casing and intake duct.
