Abstract (en)
The device has a conical, Coanda structure formed with an injection opening (51) through which air is injected in tangential direction towards the flow channel (42) between the rotor blades (11) of a compressor and guide vanes (21) of a diffuser. Another opening (52) is formed on the compressor stator wall (32) of the device at the downstream side of the injection opening. The other opening is connected to the injection opening via a formed channel (44). The other opening is formed at the downstream side of the guide vanes of the diffuser. An independent claim is included for the exhaust turbocharger including the radial compressor.
