The venturi nozzle (12) is arranged in a housing (11) of a compressor (7) of an internal combustion engine (1), where the compressor is made of a compressor impeller (13) having vanes (20). The venturi nozzle is arranged between a portion of the compressor, in which the vanes of the compressor wheel pass during operation, and a suction side (14) of the compressor. The compressor has a partially circumferential air outlet (15), where the venturi nozzle is arranged between the air outlet and the suction side of the compressor. Offenbart ist eine Venturidüse zur Erzeugung eines Unterdrucks, wobei die Venturidüse in einem Gehäuse eines Verdichters für einen Verbrennungsmotor angeordnet ist.
