Exhaust turbocharger

Exhaust gas turbocharger comprises an exhaust gas turbine (3), a turbine housing (1), in which a spiral-wound inlet channel (2) beginning with an inlet connection (5) is molded to receive an exhaust gas stream guided to the exhaust gas turbine, and devices for leading the exhaust gas stream in the winding direction (10) of the inlet channel. The guiding devices have a flow rectifier (8) arranged in the inlet connection. Preferred Features: The flow rectifier has guide elements (7) having a predominantly plate-like section (9) extending in the region of the inlet connection in the winding direction and perpendicular to this in the radial direction.
