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.Valve system for internal combustion engines, in particular for exhaust gas recirculation, with at least one housing, in which a drive unit with a drive shaft and an eccentric connected to this drive shaft, which is in operative connection with a coupling unit, and at least two valves are arranged, wherein the valves each comprise at least one valve stem, a valve closing body and a valve seat, such that the rotational movement of the drive unit is convertible into a linear synchronous movement of the valve rods, wherein the coupling unit of a bearing element (8), in which the eccentric (6) is mounted, and a coupling element (9 ), wherein the valve rods (10, 11) are mounted in the coupling element (9) and forcibly guided in the housing (18) and wherein in the region of the bearing element (8) a guide rod (17) is provided which also in the housing (18) is forced.
Description
Die
Erfindung betrifft ein Ventilsystem für Verbrennungskraftmaschinen
insbesondere zur Abgasrückführung mit mindestens
einem Gehäuse, indem 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 Ventilstange
umwandelbar ist. Ein derartiges Ventilsystem ist beispielsweise
aus der
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Ventilsystem zu schaffen, dass die o. g. Nachteile vermeidet und zudem einfach aufgebaut kostengünstig herzustellen ist.Of these, Based on the object of the invention, a valve system to create that the o. g. Disadvantages avoids and also easy to set up is inexpensive to produce.
Diese Aufgabe wird dadurch gelöst, dass die Kupplungseinheit aus einem Lagerelement, indem der Exzenter gelagert ist, und einem Koppelelement besteht, wobei die Ventilstangen in dem Koppelelement gelagert und im Gehäuse zwangsgeführt sind und wobei im Bereich des Lagerelementes eine Führungsstange vorgesehen ist, die ebenfalls im Gehäuse zwangsgeführt ist.These Task is solved in that the coupling unit from a bearing element by the eccentric is mounted, and a Coupling element consists, wherein the valve rods in the coupling element stored and forcibly guided in the housing and wherein in the region of the bearing element, a guide rod is provided, which also forcibly guided in the housing is.
Ein derartig gestaltetes Ventilsystem benötigt also zur synchronen Betätigung der Ventilstange lediglich eine Kupplungseinheit, die im Wesentlichen aus den Bauteilen Exzenter, Lagerelement und Koppelelement besteht. Auf besonders einfache Art und Weise sind die Ventilstangen durch Haltescheiben im Koppelelement axial fest angeordnet. Auch ist es möglich, das Koppelelement und die Führungsstange einteilig auszuführen.One thus designed valve system thus requires synchronous Actuation of the valve rod only one coupling unit, consisting essentially of the components eccentric, bearing element and Coupling element consists. In a particularly simple way the valve rods axially fixed by retaining washers in the coupling element arranged. It is also possible, the coupling element and to carry out the guide rod in one piece.
Ein Ausführungsbeispiel eines derartigen Ventilsystems ist in der Zeichnung dargestellt und wird nachfolgend beschrieben, hierin zeigen:One Embodiment of such a valve system is illustrated in the drawings and described below, herein demonstrate:
Gemäß
In
dem Koppelelement sind im vorliegenden Ausführungsbeispiel
zwei Ventilstangen
Um
nun eine axiale Bewegung der Ventilstangen und damit ein sicheres Öffnen
und Schließen der Ventilteller
