Abstract

Bei Drosselklappenstutzen ist es wichtig, daß die hindurchströmende Luft im Bereich kleiner Leistung der Brennkraftmaschine sehr feinfühlig gesteuert werden kann.
Bei dem hier vorgeschlagenen Drosselklappenstutzen (2) ist auf mindestens einer Stirnseite der Drosselklappe (6) mindestens eine in den Klappenumfang (26) hineinragende Vertiefung (50) vorgesehen. Dadurch wird erreicht, daß der freie Drosselquerschnitt im Bereich der Schließstellung der Drosselklappe sehr feinfühlig gesteuert werden kann.
Der Drosselklappenstutzen ist insbesondere für Verbrennungsmotoren für Fahrzeuge vorgesehen.
