Abstract

Ventilsystem für Verbrennungskraftmaschinen insbesondere zur Abgasrückführung mit mindestens einem Gehäuse, in dem eine Antriebseinheit mit einer Antriebswelle und einem mit dieser Antriebswelle verbundenen Exzenter, der in Wirkverbindung mit einer Kupplungseinheit steht, und mindestens zwei Ventile angeordnet sind, wobei die Ventile jeweils zumindest aus einer Ventilstange, einem Ventilschließkörper und einem Ventilsitz bestehen, derart, dass die rotatorische Bewegung der Antriebseinheit in eine lineare synchrone Bewegung der Ventilstangen umwandelbar ist, wobei die Kupplungseinheit aus einem Lagerelement (8), in dem der Exzenter (6) gelagert ist, und einem Koppelelement (9) besteht, wobei die Ventilstangen (10, 11) in dem Koppelelement (9) gelagert und im Gehäuse (18) zwangsgeführt sind und wobei im Bereich des Lagerelementes (8) eine Führungsstange (17) vorgesehen ist, die ebenfalls im Gehäuse (18) zwangsgeführt ist.
