Beschreibung
Zusammenfassung:	Compressor (3), especially for an internal combustion engine, comprises a compressor wheel (7) rotatably mounted in a compressor inlet channel (8) and compressing a gas to an increased boost pressure. A dead space (13) arranged in the flow region of the compressor wheel communicates exclusively with the compressor inlet channel via a connection opening adjacent to the wheel inlet edge (15) of the compressor wheel. An independent claim is also included for an exhaust gas turbocharger (1) comprising the above compressor. Preferred Features: The dead space and the connection opening are annular. The dead space is defined by a separate housing part (11) of the compressor housing (12). Ein Verdichter weist in einem Verdichtereinlasskanal ein drehbar gelagertes Verdichterrad auf, über das zugeführtes Gas auf einen erhöhten Ladedruck zu komprimieren ist. Im Anströmbereich des Verdichterrades ist ein Totraum vorgesehen, der über eine benachbart zur Radeintrittskante des Verdichterrades gelegene Verbindungsöffnung ausschließlich mit dem Verdichtereinlasskanal kommuniziert.
