Abstract

Eine VVA-Vorrichtung umfasst ein Antriebseingangskettenrad und ein einlassseitiges Übertragungskettenrad, vorgesehen zu einer einlassseitigen Phasenänderungsvorrichtung, ein auslassseitiges Übertragungskettenrad, vorgesehen zu einer auslassseitigen Phasenänderungsvorrichtung, einen Abschnitt verringerten Durchmessers, vorgesehen zu einem Gehäuse der auslassseitigen Phasenänderungsvorrichtung zwischen einem Gehäusehauptkörper und dem auslassseitigen Übertragungskettenrad, und eine Torsionsschraubenfeder, angeordnet zwischen dem Gehäuse und einem Schaufelrotor der auslassseitigen Phasenänderungsvorrichtung, zum Vorspannen der beiden in der Voreilrichtung. Die Torsionsschraubenfeder ist angeordnet auf dem Außenumfang des Abschnitts verringerten Durchmessers, um einen verringerten Durchmesser aufzuweisen, wenn die Phase sich ausgehend von der Phase bei einem Motorstart ändert.
