An exhaust gas turbocharger having inlet channels combined only directly ahead of a turbine rotor at the periphery thereof. An annular gap is arranged within the area in which the back surface and an periphery of the turbine rotor form a circumferential circular edge. A part of the exhaust gas flows from the spiral housing through the annular gap into an annular channel arranged at the rotor back surface, from which branch off a return line to the charging air channel of the compressor, and a by-pass line to a turbine exhaust gas line, by-passing the turbine. |
