Abstract

Improvements introduced in an exhaust gas turbocharger whose turbine impeller is disposed at one end and whose compressor impeller, traversed by the centrifugal current, is at the other end of a common shaft that is supported on two bearings disposed between the two impellers being provided between the space of the impeller of the compressor and the shaft bearing adjacent an outlet space oil surrounding the shaft, characterized in that between the space oil outlet (31) on the one hand and the compressor wheel (2) on the other hand, the shaft (3) is surrounded by a blocking gas space (11), limited by sealing grooves (12, 13), which through holes (10, 10a) in the housing bearing (6) is connected to a collecting chamber (15) connected to the space of the impeller (30) of the turbine casing (l7) through a slit (16) arranged on the rear side (18) of the impeller turbine (l) and that extend between the box d e bearing (b) and the turbine housing (17).
