Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein Abgasrückführventil zu schaffen, das im Hinblick auf die Vermeidung von Strömungsverlusten verbessert ist.The invention is based on the object Exhaust gas recirculation valve to create, with regard to Prevention of flow losses is improved.

Die Lösung dieser Aufgabe erfolgt durch das Abgasrückführventil gemäß Anspruch 1.The solution of this task is done by the Exhaust gas recirculation valve according to claim 1.

Demzufolge weist das erfindungsgemäße Abgasrückführventil eine Ventilöffnung und ein Ventilelement auf. Das Ventilelement ist zwischen einer die Öffnung verschließenden und einer die Öffnung freigebenden Stellung bewegbar. Für das Ventilelement sind sämtliche Ausführungsformen denkbar. Beispielsweise kann das Ventilelement ein klapp-, dreh- oder schwenkbares Element sein. Ferner ist für das Ventilelement ein tellerförmiges Element denkbar, das zum Öffnen und Schließen translatorisch verschoben wird. Erfindungsgemäß ist ein Strömungsleitelement vorgesehen. Das Ventilelement ist in der die Ventilöffnung freigebenden Stellung zumindest teilweise, von einer Strömungsmittelachse aus betrachtet, hinter dem Strömungsleitelement angeordnet. Das Strömungsleitelement dient im Wesentlichen dazu, die Abgasströmung in günstiger Weise an dem in der Öffnungsstellung befindlichen Ventilelement vorbei und möglichst ohne oder allenfalls mit geringen Strömungsverlusten durch die Ventilöffnung zu leiten. Insofern ist das Strömungsleitelement bevorzugt auf der "heißen" Seite des Abgasrückführventils vorgesehen, da von dieser Seite die Abgasströmung auf das Ventil trifft und hier in besonders günstiger Weise durch das Strömungsleitelement geleitet oder geführt werden kann. Die "heiße" Seite bedeutet in diesem Zusammenhang, dass das erfindungsgemäße Abgasrückführventil insbesondere in der Nähe des Auslasskrümmers und/oder vor einem Abgaskühler angeordnet sein kann. Aufgrund der vorangehend und nachfolgend beschriebenen Maßnahmen eignet sich das erfindungsgemäße Abgasrückführventil für eine derartige Anordnung. Es sei jedoch betont, dass es nicht notwendigerweise auf dieser Seite angeordnet sein muss, sondern ebenso gut in anderen Bereichen angeordnet sein kann und insbesondere auch so angeordnet sein kann, dass sich das Strömungsleitelement stromabwärts des Ventilelements befindet. Diese Anordnung hätte beispielsweise den Vorteil, dass die Lagerung des bevorzugt klappbaren Ventilelements sich auf der abgedichteten Seite befindet und somit in geringerem Umfang Verschmutzungen durch das anstehende Abgas unterliegt.Accordingly, the exhaust gas recirculation valve according to the invention a valve opening and a valve element. The Valve element is between a closing the opening and a position releasing the opening movable. For the Valve element, all embodiments are conceivable. For example, the valve element can be a folding, rotating or be pivotable element. Furthermore, for the valve element a plate-shaped element conceivable for opening and Close translationally shifted. According to the invention provided a flow guide. The valve element is in the valve opening releasing position at least partially viewed from a fluid axis, arranged behind the flow guide. The Flow guide essentially serves to the Exhaust flow in a favorable manner to that in the Overflow valve element located over and possibly without or at most with low To conduct flow losses through the valve opening. In this respect, the flow guide is preferably on the "hot" side of the exhaust gas recirculation valve provided as of this side the exhaust flow meets the valve and here in a particularly favorable manner by the flow guide can be directed or led. The "hot" side means in this context, that the inventive Exhaust gas recirculation valve in particular near the Exhaust manifold and / or arranged in front of an exhaust gas cooler can be. Due to the preceding and following measures described is the inventive Exhaust gas recirculation valve for such an arrangement. It was However, it emphasizes that it is not necessarily on this Side, but just as well in others Areas may be arranged and in particular also so may be arranged that the flow guide located downstream of the valve element. This arrangement For example, would have the advantage that the storage of the preferably hinged valve element on the sealed side and thus to a lesser extent Contaminated by the upcoming exhaust gas is subject.

Die Tatsache, dass das Ventilelement in der die Öffnung freigebenden Stellung zumindest teilweise hinter dem Strömungsleitelement angeordnet ist, führt zu mehreren Vorteilen. Zunächst ist zu dieser Anordnungsbeziehung zu sagen, dass sie von einer Strömungsmittelachse betrachtet erkennbar ist. Mit anderen Worten wird diejenige Stelle in der Strömung betrachtet, an der sich das Ventilelement in dem geöffneten Zustand befindet. Erfindungsgemäß ist an dieser Stelle der Strömung, also in Strömungsrichtung an der Stelle des geöffneten Ventilelements, das Ventilelement zumindest teilweise nicht zu sehen, weil es zumindest teilweise durch das Strömungsleitelement "abgedeckt" wird. Durch diese "abgedeckte" Position hinter dem Strömungsleitelement wird verhindert, dass das geöffnete Ventilelement die Strömung umfangreich beeinflusst. Hierdurch können Strömungsverluste reduziert werden. Ferner ist das Ventilelement in günstiger Weise abgeschirmt, was die Temperaturbelastung angeht. Das Strömungsleitelement isoliert das Ventilelement gewissermaßen thermisch von der heißen Abgasströmung, so dass durch die erfindungsgemäße Anordnung eine Öffnung des Ventilelements in Richtung der "heißen" Seite möglich wird. In dieser geöffneten Stellung wird nämlich eine thermische Überbelastung des Ventilelements durch die Abdeckung mittels des Strömungsleitelements verhindert.The fact that the valve element in the the opening releasing position at least partially behind the Flow guide is arranged, leading to several Benefits. First of all, there is too much to this relationship say that she is looking from a fluid axis is recognizable. In other words, the one place in considered the flow at which the valve element in the open state is located. According to the invention is at this Place the flow, ie in the flow direction at the point of the opened valve element, the valve element at least partly not seen because it is at least partially through the flow guide is "covered". Through this "covered" position behind the flow guide is prevents the open valve element from flowing extensively influenced. This can flow losses be reduced. Furthermore, the valve element is cheaper Shielded as regards the temperature load. The Flow guide isolates the valve element in a sense thermally from the hot exhaust gas flow, so that through the inventive arrangement an opening of the valve element in Direction of the "hot" side becomes possible. In this opened position is namely a thermal Overloading of the valve element by the cover means prevents the flow guide.

Die Öffnung des Ventilelements in Richtung der heißen Seite eines Abgasrückführventils bietet den Vorteil, dass der anstehende Abgasdruck das Ventilelement in den geschlossenen Zustand drückt. Deshalb müssen für den geschlossenen Zustand keine aufwändigen Maßnahmen vorgesehen sein, um ein Verschließen der Ventilöffnung sicherzustellen. Vielmehr drückt der anstehende Abgasdruck selbst das Ventil in die geschlossene Stellung. Ein Öffnen des Ventilelements gegen diesen anstehenden Gasdruck kann mit vergleichsweise einfachen Maßnahmen gewährleistet werden. Jedenfalls ist die Öffnung des Ventils gegen den anstehenden Abgasdruck einfacher zu realisieren, als wenn die Aufrechterhaltung des geschlossenen Zustands gegen den Gasdruck sicherzustellen wäre. Im Zusammenhang mit der Öffnung des erfindungsgemäßen Abgasrückführventils ist zu erwähnen, dass diese beispielsweise gemäß der von der Anmelderin beim Europäischen Patentamt am 24. Oktober 2003 eingereichten europäischen Patentanmeldung mit der Anmeldenummer 03 024 509 und der beim Europäischen Patentamt am 25. März 2003 eingereichten europäischen Patentanmeldung mit der Anmeldenummer 03 006 733 realisiert werden kann. Ferner kann das Ventilelement selbst im Hinblick auf die Anordnung der Drehachse im Fall eines drehbaren Ventils so gestaltet sein, wie dies in der EP 1 245 820 A1 beschrieben ist. Diese Anmeldungen wurden im Hinblick auf die genannten Merkmale zum Gegenstand der vorliegenden Anmeldung gemacht. Schließlich ist zu erwähnen, dass auch in der Verwendung eines Strömungsleitelements bei einem Abgasrückführventil alleine eine Neuerung gesehen wird, die gegenüber den bislang bekannten Anordnungen ihre Vorteile entfaltet. Insofern ist auch ein Abgasrückführventil mit einem Strömungsleitelement, nicht unbedingt mit den weiteren, oben beschriebenen Merkmalen, jedoch gegebenenfalls mit einer beliebigen Kombination der vorangehend und nachfolgend erläuterten bevorzugten Merkmale, als Gegenstand der Anmeldung zu betrachten.The opening of the valve element in the direction of the hot side an exhaust gas recirculation valve has the advantage that the Pending exhaust pressure the valve element in the closed State presses. Therefore, for the closed state No elaborate measures should be provided to one Ensure the valve opening is closed. Much more the upcoming exhaust pressure itself presses the valve into the closed position. An opening of the valve element against This upcoming gas pressure can be compared with simple measures. Anyway, that is Opening the valve against the upcoming exhaust pressure easier to realize than if the maintenance of the ensure closed condition against the gas pressure would. In connection with the opening of the invention Exhaust gas recirculation valve is to mention that this For example, according to the applicant of the European Patent Office filed on 24 October 2003 European Patent application with the application number 03 024 509 and the at European Patent Office on 25 March 2003 European patent application with the application number 03 006 733 can be realized. Furthermore, the valve element itself with regard to the arrangement of the axis of rotation in the case of rotatable valve be designed as in the EP 1 245 820 A1. These registrations were in With regard to the features mentioned, the subject matter of made this application. Finally, it should be mentioned that also in the use of a flow guide at an exhaust gas recirculation valve alone is seen as an innovation, the advantages over the previously known arrangements unfolded. In this respect, an exhaust gas recirculation valve with a flow guide, not necessarily with the other, features described above, but optionally with a any combination of the foregoing and following explained preferred features, as subject of the Registration to look at.

Als Unterschied zu dem Gegenstand der EP 1 342 907 A2 ist zu betonen, dass bei diesem bekannten Abgasrückführventil zwar eine der Steuerscheiben hinter der anderen Steuerscheibe angeordnet ist. Die "vordere" Steuerscheibe ist jedoch ein Teil des Ventils und weist, bei dieser Betrachtung, Ventilöffnungen auf, so dass sie nicht als Strömungsleitelement betrachtet werden kann. Im Gegensatz dazu weist das Strömungsleitelement des erfindungsgemäßen Abgasrückführventils eine gewisse Erstreckung in Strömungsrichtung auf, so dass die Strömung zuverlässig geleitet wird, und "hinter" dem Strömungsleitelement das geöffnete Ventilelement angeordnet werden kann, während es im geschlossenen Zustand vor oder neben dieser bewegt wird. hierdurch geht von letzterem keine nachteilige Beeinflussung der Strömung aus.As a difference from the subject matter of EP 1 342 907 A2 is to emphasize that in this known exhaust gas recirculation valve while one of the control discs behind the other control disc is arranged. However, the "front" control disc is on Part of the valve and points, in this consideration, Valve openings on, so they are not considered Flow guide can be considered. In contrast For this purpose, the flow guide of the invention Exhaust gas recirculation valve a certain extent in Direction of flow, so that the flow is reliable is passed, and "behind" the flow guide the opened valve element can be arranged while it is in closed state before or next to this is moved. this does not adversely affect the latter the flow out.

Bevorzugte Weiterbildungen des erfindungsgemäßen Abgasrückführventils sind in den weiteren Ansprüchen beschrieben.Preferred developments of the invention Exhaust gas recirculation valve are in the further claims described.

Bevorzugt ist das Ventilelement bezüglich der Strömung derart anordenbar, dass die Öffnung gegen die Strömungsrichtung erfolgt. Diese Anordnung ist insofern günstig, als nicht durch besondere Mechanismen dafür gesorgt werden muss, dass das Ventilelement gegen den anstehenden Gasdruck geschlossen bleibt. Vielmehr drückt das anstehende Gas selbst das Ventilelement in die geschlossene Stellung. Wie erwähnt, wird diese vorteilhafte Anordnung durch das erfindungsgemäße Strömungsleitelement möglich, indem das Ventilelement in seiner geöffneten Stellung vor den heißen Gasen geschützt und zumindest teilweise thermisch isoliert werden kann. Preferably, the valve element with respect to the flow is so can be arranged that the opening against the flow direction he follows. This arrangement is favorable, as not through special mechanisms must be ensured that closed the valve element against the upcoming gas pressure remains. Rather, the upcoming gas itself presses that Valve element in the closed position. As mentioned, will this advantageous arrangement by the invention Flow guide possible by the valve element in its open position protected from the hot gases and at least partially thermally isolated.

Für das Strömungsleitelement wird derzeit ein Rohrabschnitt bevorzugt. Das Rohr kann einen kreisrunden Querschnitt aufweisen und insoweit an den Querschnitt der Abgasrückführleitung angepasst sein. Durch ein Strömungsleitelement mit dieser Form kann eine besonders gute Führung der Strömung erreicht werden. Es sind jedoch auch andere Querschnitte für das Rohr möglich. Als Beispiele seien ein ovaler, rechteckiger oder mehreckiger Querschnitt genannt.For the flow guide is currently a pipe section prefers. The tube can have a circular cross-section and to that extent to the cross section of Be adapted exhaust gas recirculation line. Through a Flow guide with this shape can be a particularly good Leadership of the flow can be achieved. There are, however other cross sections for the pipe possible. As examples are an oval, rectangular or polygonal cross section called.

Für das Strömungsleitelement hat es sich ferner als günstig erwiesen, wenn es, über den Querschnitt der Ventilöffnung oder der Abgasrückführleitung, an zumindest einem Ende schräg ausgebildet ist. Beispielsweise kann ein Rohrabschnitt an zumindest einem Ende bezüglich der Strömungsmittelachse schräg oder geneigt abgeschnitten sein. Hierdurch kann in günstiger Weise die beschriebene, vorteilhafte Abdeckungsfunktion des Strömungsleitelements genutzt werden, ohne die erforderlichen Bewegungen des Ventilelements zu behindern.For the flow guide, it also has to be favorable proved, if it, over the cross section of the valve opening or the exhaust gas recirculation line, obliquely at least at one end is trained. For example, a pipe section at least one end with respect to the fluid axis be cut off obliquely or inclined. This can be done in favorably the described, advantageous Cover function of the flow guide can be used, without the required movements of the valve element hinder.

Für das Ventilelement wird derzeit bevorzugt, dass es klapp-, dreh- oder schwenkbar ausgeführt ist. Mit dieser Art von Bewegung lässt sich das Ventilelement besonders einfach in die "geschützte" Stellung hinter das Strömungsleitelement bringen. Es sei jedoch betont, dass dieser Vorteil auch bei einem translatorisch bewegten Ventilelement erreicht werden kann.It is presently preferred for the valve element to be hinged, is designed to rotate or swivel. With this kind of Movement makes the valve element particularly easy in the "protected" position behind the flow guide bring. It should be stressed, however, that this benefit is also at a translationally moving valve element can be achieved can.

Für die Drehachse eines klappbaren Ventilelements erweist es sich als günstig, wenn diese außerhalb der Ebene der Ventilöffnung angeordnet ist. Dies führt zu dem Vorteil, dass das Ventilelement über seinen Umfang durchgehend und nicht durch Teile der Drehachse unterbrochen ist, so dass eine besonders zuverlässige Abdichtung erzeugt wird. Ferner kann durch die beschriebene Anordnung der Drehachse in günstiger Weise erreicht werden, dass das Ventilelement in die geschützte Position hinter dem Strömungsleitelement gebracht werden kann.For the axis of rotation of a hinged valve element it proves to be cheap if this is outside the level of Valve opening is arranged. This leads to the advantage that the valve element is continuous over its circumference and not is interrupted by parts of the rotation axis, so that a particularly reliable seal is generated. Furthermore, can by the described arrangement of the axis of rotation in cheaper Be achieved, that the valve element in the protected position brought behind the flow guide can be.

Dies wird durch diejenige bevorzugte Ausführungsform begünstigt, bei der die Drehachse bezüglich der Strömungsmittelachse exzentrisch vorgesehen ist. Hierdurch können die Bewegungen des Ventilelements bezüglich des Ventilsitzes so eingestellt werden, dass sowohl ein zuverlässiges Verschließen der Ventilöffnung als auch ein sanftes Lösen des Ventilelements von der Ventilöffnung erreicht wird.This is by the preferred embodiment favors, in which the axis of rotation with respect Fluid axis is provided eccentrically. hereby can the movements of the valve element with respect to the Valve seat can be adjusted so that both a reliable closing of the valve opening as well gently releasing the valve element from the valve opening is reached.

Für das Ventilelement wird ferner bevorzugt, dass dieses an der der Ventilöffnung zugewandten Seite weitgehend kegel(stumpf)förmig oder sphärisch gestaltet ist. Hierdurch kann eine besonders günstige Zusammenwirkung mit dem Ventilsitz, der die Ventilöffnung begrenzt, erreicht werden.For the valve element is further preferred that this the valve opening facing side largely cone (blunt) shaped or spherical. hereby can be a particularly favorable interaction with the Valve seat, which limits the valve opening can be achieved.

Schließlich hat es sich für den Strömungsverlauf als vorteilhaft erwiesen, wenn im Bereich des Abgasrückführventils ein Aufnahmeraum für das Ventilelement in dessen geöffneter Stellung vorgesehen ist, der hinsichtlich seiner Form an die Form des Ventilelements selbst sowie dessen Bewegung von der geschlossenen in die geöffnete Stellung angepasst ist. Hierdurch ergibt sich der Vorteil, dass das Ventilelement in seiner geöffneten Stellung vollständig aus der Strömung herausbewegt ist, so dass diese in äußerst geringem Umfang beeinträchtigt wird.Finally, it has to be for the flow as proven advantageous when in the field of Exhaust gas recirculation valve a receiving space for the valve element is provided in its open position, the in terms of its shape to the shape of the valve element itself as well as its movement from the closed into the open position is adjusted. This results in the Advantage that the valve element in its open position is completely moved out of the flow, so this is negatively affected.

Ausführliche Beschreibung einer bevorzugten AusführungsformDetailed description of a preferred embodiment

Das in Fig. 1 gezeigte Abgasrückführventil 10 ist in einem Abschnitt der Abgasrückführleitung angeordnet und ist zu diesem Zweck an seinen jeweiligen Enden mit Flanschen 12 versehen, die eine Montage in der Abgasrückführleitung ermöglichen. Die Ventilöffnung 14 ist etwa kreisförmig und wird durch einen Ventilsitz definiert. Mit dem Ventilsitz wirkt ein Ventilelement 16 zusammen, das in Übereinstimmung mit dem Ventilsitz in etwa kreisförmig ist. An der der Ventilöffnung zugewandten Seite ist das Ventilelement 16 in dem gezeigten Fall sphärisch gestaltet. Bei dem gezeigten Ausführungsbeispiel besteht das Ventilelement ferner aus drei Teilen. Ein erstes Teil 18 bildet einen Grundkörper, an dem für die eigentliche Zusammenwirkung mit dem Ventilsitz ein ringförmiges Element 20 angebracht ist. An der der Ventilöffnung zugewandten Seite ist ein drittes Element 22 vorgesehen, das die auf dieser Seite sphärische Gestaltung vervollständigt.The exhaust gas recirculation valve 10 shown in Fig. 1 is in one Section of the exhaust gas recirculation line disposed and is closed this purpose at its respective ends with flanges 12th provided, which is an assembly in the exhaust gas recirculation line enable. The valve opening 14 is approximately circular and is defined by a valve seat. With the valve seat a valve element 16 cooperates in accordance with the valve seat is approximately circular. At the Valve opening facing side is the valve element 16 in Spherical designed in the case shown. In the shown In the embodiment, the valve element further consists of three Share. A first part 18 forms a base body on which for the actual interaction with the valve seat annular element 20 is attached. At the Valve opening facing side is a third element 22nd provided that the spherical design on this page completed.

Der Grundkörper 18 ist im Bereich der Ventilöffnung weitgehend kreisförmig gestaltet. Integral an diesen Bereich angeschlossen sind zwei Abschnitte, die als Arme bezeichnet werden können, von denen in Fig. 1 wegen der Schnittdarstellung nur einer zu erkennen ist, und die für die Anbindung an die jeweilige Drehachse sorgen. Da bei dem gezeigten Beispiel die Drehachse sowohl außerhalb der Ebene der Ventilöffnung als auch bezüglich der Strömungsmittelachse exzentrisch, in dem gezeigten Fall nach unten versetzt ist, kann die Drehachse geteilt ausgebildet werden. Der vordere Teil der Drehachse ist in Fig. 1 wegen der Schnittdarstellung nicht zu erkennen, und der "hintere" Teil ist gemäß der Darstellung von Fig. 1 durch das nachfolgend noch genauer erläuterte Strömungsleitelement 24 abgedeckt. Aus den weiteren Figuren geht jedoch die Anordnung der Drehachse genauer hervor.The main body 18 is in the region of the valve opening designed largely circular. Integral to this area connected are two sections, referred to as arms of which in Fig. 1 because of the Only one can be seen, and the one for the Ensure connection to the respective axis of rotation. As with the shown example, the axis of rotation both outside the plane the valve opening as well as with respect to the fluid axis eccentric, in the case shown offset downwards, the axis of rotation can be formed divided. The front Part of the rotation axis is in Fig. 1 because of the sectional view not recognizable, and the "back" part is according to the Representation of Fig. 1 by the following in more detail explained flow guide 24 covered. From the However, other figures is the arrangement of the axis of rotation in more detail.

Bei dem Strömungsleitelement 24 handelt es sich um einen Abschnitt eines Rohres, das in die gezeigte Ventilanordnung von einer Seite her, gemäß der Darstellung von Fig. 1 von der rechten Seite her, eingesetzt und durch einen Flansch 26 abgestützt ist. Bei dem gezeigten Beispiel liegt das das Strömungsleitelement bildende Rohr nur im Bereich des rechten Endes an der Innenseite der Abgasrückführleitung an. Auch hier erfolgt durch die Ausbildung von Rippen 28 das Anliegen nur stellenweise. Diese Gestaltung, insbesondere die Ausbildung von Rippen, ist insbesondere dann vorgesehen, wenn sich das Abgasrückführventil auf der "heißen" Seite befindet. Durch die Berührung, die lediglich im Bereich der Rippen 28 vorliegt, wird der Wärmeübergang zu dem Strömungsleitelement verschlechtert. Bei einer anderen Anordnung des Abgasrückführventils, beispielsweise auf der "kalten" Seite, kann die Anbringung selbstverständlich anders gestaltet sein, insbesondere könnten die Rippen 28 weggelassen werden.The flow guide 24 is a Section of a pipe, which in the valve assembly shown from one side, according to the illustration of Fig. 1 of the right side, inserted and by a flange 26th is supported. In the example shown this is the case Flow guide forming tube only in the area of the right End on the inside of the exhaust gas recirculation line. Also Here, by the formation of ribs 28, the concern only in places. This design, especially the Formation of ribs, is especially provided when the exhaust gas recirculation valve is on the "hot" side. By the touch, the only in the ribs 28 is present, the heat transfer to the flow guide deteriorated. In another arrangement of Exhaust gas recirculation valve, for example on the "cold" side, Of course, the attachment can be different, In particular, the ribs 28 could be omitted.

An derjenigen Seite, mit der das Strömungsleitelement 24 der Ventilöffnung 16 zugewandt ist, ist dieses schräg abgeschnitten. Mit anderen Worten ist es an einer Seite, gemäß Fig. 1 der Unterseite, länger als an (gemäß Fig. 1) der Oberseite. Diese Ausbildung dient dazu, die Strömungsleitfunktion zu erfüllen, jedoch die zum Öffnen erforderliche Bewegung des Ventilelements 16 nicht zu behindern. Diese erfolgt, wie in den weiteren Figuren besser zu erkennen, durch eine Drehung in Richtung des Uhrzeigersinns. Für die geöffnete Stellung des Ventilelements 16 ist ein Aufnahmeraum 30 vorgesehen, der weitgehend sphärisch konkav gestaltet ist und an die Bewegung und Form des Ventilelements angepasst ist. Im Bereich dieses Aufnahmeraums 30 ist in der Umgebung des gezeigten Abgasrückführventils 10, und integral damit ausgebildet, ein Bereich 32 zu erkennen, der beispielsweise für die Kühlung des Abgasrückführventils sowie für die Anbringung der erforderlichen Antriebe, Sensoren und dergleichen verwendet werden kann.At that side, with the flow guide 24 of the Valve opening 16 faces, this is oblique cut off. In other words, it's on one side, 1 of the bottom, longer than (according to FIG. 1) of Top. This training serves the To meet flow control function, but the opening required movement of the valve element 16 is not too hinder. This takes place, as in the other figures better to be recognized by a rotation in the direction of the Clockwise. For the open position of the valve element 16, a receiving space 30 is provided which is largely is spherically concave and adapted to the movement and shape the valve element is adapted. In the area of this Recording room 30 is in the vicinity of the one shown Exhaust gas recirculation valve 10, and integrally formed therewith To recognize area 32, for example, for cooling the exhaust gas recirculation valve and for the attachment of required drives, sensors and the like used can be.

In Fig. 2 ist das in Fig. 1 gezeigte Abgasrückführventil während des Öffnens des Ventilelements 20 gezeigt. Für den Ventilsitz 14 ist in Fig. 2 zu erkennen, dass er in den Grundkörper des Abgasrückführventils 10 als gesondertes Element eingesetzt ist und auf derjenigen Seite, die mit dem Ventilelement 20 zusammenwirkt, kegelig oder sphärisch abgeschrägt ist. Für das Ventilelement 20 ist zu erkennen, dass es aufgrund der Anordnung der Drehachse außerhalb der Ebene des Ventilelements 20 an einen Rand des gezeigten Abschnitts der Abgasrückführleitung bewegt werden kann. Hierbei beschreibt der in Richtung der Drehbewegung gerichtete Rand 34 des Ventilelements 20 eine kreisförmige Bahn, die sich in der Form des Aufnahmeraums 30 widerspiegelt. Für das Strömungsleitelement 24 ist zu erkennen, dass es die beschriebene Bewegung des Ventilelements 20 ermöglicht und nicht behindert, indem es in dem Bereich, in den das Ventilelement 20 bewegt wird, durch das schräge Abschneiden an seinem einen Ende kürzer ist als an der gegenüberliegenden Seite.In Fig. 2, the exhaust gas recirculation valve shown in Fig. 1 is shown during opening of the valve element 20 shown. For the Valve seat 14 can be seen in Fig. 2, that he in the Main body of the exhaust gas recirculation valve 10 as a separate Element is inserted and on the side that with the Valve element 20 cooperates, conical or spherical is bevelled. For the valve element 20 can be seen that it is due to the arrangement of the rotation axis outside the Level of the valve element 20 to an edge of the shown Section of the exhaust gas recirculation line can be moved. This describes in the direction of the rotational movement directed edge 34 of the valve element 20 is a circular Railway, which takes the form of the reception room 30 reflects. For the flow guide 24 is too recognize that it is the described movement of the Valve element 20 allows and does not obstruct by putting it in the area in which the valve element 20 is moved through the oblique cut off at its one end is shorter than on the opposite side.

In Fig. 3 ist die vollständig geöffnete und die Ventilöffnung freigebende Stellung des Ventilelements 20 gezeigt. Das Ventilelement 20 ist in dem Aufnahmeraum 30 untergebracht und wird weitgehend durch das Strömungsleitelement 24 abgedeckt. In Fig. 3, the fully open and the valve opening releasing position of the valve element 20 is shown. The Valve element 20 is housed in the receiving space 30 and is largely covered by the flow guide 24.

Mit anderen Worten, wenn das Ventilelement 20 von derjenigen Stelle in der Strömung aus, an der sich das Ventilelement 20 in der geöffneten Stellung befindet, betrachtet wird, ist es größtenteils hinter dem Strömungsleitelement 24 verborgen. Somit erfolgt nahezu keine Beeinflussung der Strömung durch das geöffnete Ventilelement. Ferner kann dieses auf der heißen Seite der Abgasrückführleitung geöffnet werden und ist in thermischer Hinsicht durch das Strömungsleitelement 24 abgeschirmt. In günstiger Weise erstreckt sich die Ebene des Ventilelements 20 weitgehend parallel zur Außenwand des Strömungsleitelements 24, so dass der verfügbare Bauraum besonders gut genutzt wird.In other words, when the valve element 20 of that Position in the flow at which the valve element 20 is in the open position, it is considered mostly hidden behind the flow guide 24. Thus, there is almost no influence on the flow the opened valve element. Furthermore, this can be on the hot side of the exhaust gas recirculation line to be opened and is in thermal terms by the flow guide 24th shielded. Conveniently, the level of the Valve element 20 largely parallel to the outer wall of the Flow guide 24, so that the available space is used particularly well.
