Abstract

Klappenvorrichtungen für Abgassysteme von Verbrennungskraftmaschinen mit einem einen Kanal (4) bildenden Gehäuse (2), einem Klappenkörper (14), der an einer Welle (12) befestigt ist mit dieser über einen Aktuator (26) betätigbar ist und einen Durchströmungsquerschnitt des Kanals beherrscht, sind bekannt. Die Lagerung erfolgt normalerweise über Nadellager. Diese sind jedoch bezüglich auftretender Toleranzen bei der Wellenherstellung und der Herstellung der als Lagerstellen (8, 10) dienenden Gehäusebohrung (6) sowie gegen Schmutzablagerung, Korrosion und Eisbildung empfindlich.
Es wird daher vorgeschlagen, dass zumindest eines der Lager der Lagereinheit (28) eine Kunststoffbuchse (36) ist. Dies bewirkt einen guten Toleranzausgleich, so dass deutliche Kostenvorteile bei der Herstellung entstehen.
