Abstract

Durch die Trennung verschiedener Abgasstränge in einer Verbrennungskraftmaschine ist es notwendig geworden, mehrere Abgasrückführventile einzusetzen, die jeweils über einen eigenen Antrieb verfügen. Mit dem erfindungsgemäßen Gegenstand ist ein Ventilsystem geschaffen worden, welches mehrere Ventile über eine Antriebseinheit antreibt und somit geringere Kosten durch Reduzierung der Anzahl der Bauteile und des Montageaufwands entstehen. Dies wird dadurch erreicht, daß eine Kupplungseinheit, die eine Antriebseinheit mit den verschiedenen Ventilstangen verbindet.
