ABSTRACT:
The invention concerns a device for changing the flow direction of an airflow entering the suction-side opening of a compressor of an exhaust gas turbo-charger of an internal combustion engine. The airflow is deflected into the rotational direction of the compressor impeller by means of a guide device located in the induction duct upstream of the inlet opening. In order to achieve required flow through a mechanically simply producible guide device, a bypass duct which has an annular space branches off from the induction duct upstream of the compressor to the guide device. The annular space surrounds the induction duct in the region of the suction-side opening of the compressor. Nozzle-shaped openings are provided in a common partition between the annular space and the induction duct and a shut-off valve is located in the induction duct between these openings and the point where the bypass duct branches off.
