Description
Die Erfindung betrifft ein Klappenventil zur Einleitung und Steuerung eines Frischluftstromes und eines Abgasrückführstromes mit einem Gehäuse, das einen Frischluftkanal und einen Abgasrückführkanal aufweist, in dem ein erster und ein zweiter Klappenkörper auf einer Antriebswelle gelagert sind, wobei der erste Klappenkörper mit dem Frischluftkanal und der zweite Klappenkörper mit dem Abgasrückführkanal korrespondiert, und mit einem Stellantrieb für die Antriebswelle.The invention relates to a flap valve for initiating and controlling a fresh air flow and an exhaust gas recirculation flow with a housing having a fresh air passage and an exhaust gas recirculation passage in which a first and a second valve body are mounted on a drive shaft, wherein the first valve body with the fresh air passage and the second Damper body corresponds to the exhaust gas recirculation passage, and with an actuator for the drive shaft.

Bei beiden Ausführungsformen gestaltet sich die Montage aufgrund vielseitiger Orientierungsmöglichkeiten des ersten Klappenkörpers aufwendig. Auch ist eine Mindestmenge an zuzuführender Frischluft (Fail-Safe-Position) nur über eine bestimmte Klappenstellung zu erreichen.In both embodiments, the assembly designed consuming due to versatile orientation possibilities of the first valve body. Also, a minimum amount of fresh air to be supplied (fail-safe position) can only be achieved via a specific flap position.
Es stellt sich daher die Aufgabe, ein gattungsgemäßes Klappenventil zu schaffen, das mit einem Stellantrieb zu betätigen ist, und das bei geringen und flexiblen Bauraumanforderungen sowie geringem Gewicht einfach und kostengünstig herstellbar ist.It therefore has as its object to provide a generic flapper valve, which is to operate with an actuator, and which is simple and inexpensive to produce with low and flexible space requirements and low weight.
Diese Aufgabe wird dadurch gelöst, dass der Abgasrückführkanal in den Frischluftkanal hineinreicht, wobei der erste Klappenkörper und der zweite Klappenkörper überlappend angeordnet sind und eine gemeinsame Drehachse aufweisen. Auf diese Weise wird ein besonders einfach und günstig herzustellendes Klappenventil bereit gestellt, das sehr klein verbaut werden kann und darüber hinaus auch noch flexibel den vom Motorenhersteller vorgegebenen Bedingungen anzupassen ist.This object is achieved in that the exhaust gas recirculation passage extends into the fresh air passage, wherein the first valve body and the second valve body are arranged overlapping and have a common axis of rotation. In this way, a particularly simple and inexpensive to produce flap valve is provided, which can be installed very small and beyond also flexible to adjust the conditions specified by the engine manufacturer.
Vorzugsweise ist der erste Klappenkörper mit der Antriebswelle verbunden und der zweite Klappenkörper auf dem ersten Klappenkörper angeordnet. Hierdurch ist ein modulartiger Aufbau des Klappenventils realisierbar, wodurch die Montage erheblich vereinfacht wird.Preferably, the first flap body is connected to the drive shaft and the second flap body is arranged on the first flap body. As a result, a modular construction of the flap valve can be realized, whereby the assembly is considerably simplified.
Besonders vorteilhaft ist es, wenn der erste und der zweite Klappenkörper in einer Ebene angeordnet sind. Hierdurch wird die Montage noch einmal wesentlich vereinfacht, da ein Ausrichten der Klappenkörper zueinander entfallen kann.It when the first and the second flap body are arranged in a plane is particularly advantageous. As a result, the assembly is once again considerably simplified, since an alignment of the valve body to each other can be omitted.
In einer weiterführenden Ausführungsform verläuft die Antriebswelle exzentrisch zur Querachse des Frischluftkanals. Hierdurch ist es möglich, dass der Leckluftanteil der Frischluft verringert wird und der Öffnungsgrad des Frischluftkanals dementsprechend genauer einstellbar ist.In a further embodiment, the drive shaft is eccentric to the transverse axis of the fresh air passage. This makes it possible that the leakage air content of the fresh air is reduced and the opening degree of the fresh air duct is accordingly more precisely adjustable.
In einer weiteren vorteilhaften Ausführung ist der erste Klappenkörper teilkreisförmig ausgebildet. Mit einer derartigen Ausführung ist der Klappenkörper abhängig von der Lage der Antriebswelle einfach der Innenkontur des Frischluftkanals an zu passen.In a further advantageous embodiment, the first valve body is formed part-circular. With such an embodiment of the valve body is easily dependent on the position of the drive shaft of the inner contour of the fresh air duct to fit.
Um zu gewährleisten, dass Abgas nicht unerwünscht aus dem Abgasrückführkanal austritt, besteht der zweite Klappenkörper aus einem Dicht- und einem Haltekörper.In order to ensure that exhaust gas does not escape undesirably from the exhaust gas recirculation passage, the second valve body consists of a sealing body and a holding body.
Ein Ausführungsbeispiel eines erfindungsgemäßen Klappenventils ist in der Zeichnung dargestellt und wird nachfolgend anhand der Figuren beschrieben.An embodiment of a flap valve according to the invention is shown in the drawing and will be described below with reference to FIGS.

Es sollte deutlich sein, dass für die Herstellung der Klappenkörper sowie des Klappengehäuses grundsätzlich sämtliche Werkstoffe geeignet sind. Durch die Verwendung von Kunststoff wird eine besonders leichte Ausführungsform geschaffen.It should be clear that basically all materials are suitable for the production of the valve body and the valve body. The use of plastic creates a particularly lightweight embodiment.
