Abstract

Bekannte Sekundärluftfördereinrichtungen weisen jeweils ein separates Verdichterrad und ein Turbinenrad auf. Die Schaufeln von Verdichterrad und Turbinenrad sind in einem Gehäuse eingebracht, wobei zwischen den Schaufeln und dem Gehäuse stets ein Radialspalt vorliegt, der zu Verlusten führt. Die Abdichtung der Schaufeln zum Gehäuse hin ist stets problematisch. DOLLAR A Zur verbesserten Abdichtung und einfachen Bauweise wird erfindungsgemäß vorgeschlagen, das Verdichterrad und das Turbinenrad in Form eines gemeinsamen, kombinierten Bauteils als ein Laufrad (1) mit an einer Seite (12) vorgesehener Verdichterbeschaufelung (3) und mit an gegenüberliegender Seite (11) vorgesehener Turbinenbeschaufelung (4) auszuführen, wobei zwischen einem Gehäuse (26) der Sekundärluftfördereinrichtung und dem Laufrad (1) eine Dichtung (23; 28; 33; 35) vorgesehen ist. DOLLAR A Das erfindungsgemäße Verdichter- und Turbinenrad ist für Sekundärluftfördereinrichtungen für Brennkraftmaschinen vorgesehen.
