The invention relates to a turbocharger, in particular an exhaust gas turbocharger, having a turbine 5 for converting energy in an exhaust gas flow into mechanical energy in order to drive a compressor 3. A fresh air mass flow 10 is fed to the compressor 3 of the turbocharger. In order to cool the blades of the compressor an injection device 16 is connected upstream of the compressor 3 for injecting a liquid 15 into the charge air mass flow 10 before its entry into the compressor 3. The liquid 15, such as water, evaporates in the compressor 3 and thus brings about its cooling. The liquid 15 may be compressed and heated in a heat exchanger 18 before it is injected into the airflow upstream of the compressor. |
