Abstract
Die Erfindung betrifft ein Abgasrückführungsventil (1) für eine Abgasanlage einer Verbrennungskraftmaschine mit einem Gehäuse (2), in dem ein mit Abgas durchströmbarer Strömungskanal (3) gebildet ist, einer schwenkbar in dem Gehäuse (2) gelagerten Welle (4) und einer mit der Welle (4) gekoppelten Ventilklappe (7) zum Verschließen des Strömungskanals (3). Erfindungsgemäß ist die Welle (4) zumindest in einem Bereich zumindest einer Durchführung der Welle (4) durch das Gehäuse (2) von einer Hülse (8, 9) umgeben, wobei die Ventilklappe (7) an einem stirnseitigen Verbindungsbereich mit der Welle (4) eine die Welle (4) vollständig umlaufende Aussparung (7.3) aufweist, in welche die Hülse (8) mit einem Ende hineinragt.The invention relates to an exhaust gas recirculation valve (1) for an exhaust system of an internal combustion engine having a housing (2) in which a throughflowable with exhaust gas flow channel (3) is formed, a pivotally mounted in the housing (2) shaft (4) and one with the Shaft (4) coupled valve flap (7) for closing the flow channel (3). According to the invention, the shaft (4) is surrounded by a sleeve (8, 9) through the housing (2) at least in one area of at least one passage of the shaft (4), the valve flap (7) being connected to the shaft (4) at an end connection area ) has a shaft (4) completely circumferential recess (7.3) into which the sleeve (8) protrudes with one end.
Description
Die Erfindung betrifft ein Abgasrückführungsventil gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an exhaust gas recirculation valve according to the preamble of

Der Erfindung liegt die Aufgabe zu Grunde, ein gegenüber dem Stand der Technik verbessertes Abgasrückführungsventil für eine Abgasanlage einer Verbrennungskraftmaschine anzugeben.The invention is based on the object of specifying an improved compared to the prior art exhaust gas recirculation valve for an exhaust system of an internal combustion engine.
Die Aufgabe wird erfindungsgemäß mit einem Abgasrückführungsventil gelöst, welches die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved with an exhaust gas recirculation valve, which has the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Das Abgasrückführungsventil für eine Abgasanlage einer Verbrennungskraftmaschine umfasst ein Gehäuse, in dem ein mit Abgas durchströmbarer Strömungskanal gebildet ist, eine schwenkbar in dem Gehäuse gelagerte Welle und eine mit der Welle gekoppelte Ventilklappe zum zumindest teilweisen, jedoch bevorzugt vollständigen Verschließen des Strömungskanals.The exhaust gas recirculation valve for an exhaust system of an internal combustion engine comprises a housing in which a flow-through with exhaust gas flow channel is formed, a pivotally mounted in the housing shaft and coupled to the shaft valve flap for at least partially, but preferably complete closing of the flow channel.
Erfindungsgemäß ist die Welle zumindest in einem Bereich zumindest einer Durchführung der Welle durch das Gehäuse von einer Hülse umgeben, wobei die Ventilklappe an einem stirnseitigen Verbindungsbereich mit der Welle eine die Welle vollständig umlaufende Aussparung aufweist, in welche die Hülse mit einem Ende hineinragt.According to the invention, the shaft is surrounded by a sleeve at least in a region of at least one passage of the shaft, wherein the valve flap has at a front-side connection region with the shaft a recess which completely surrounds the shaft and into which the sleeve protrudes with one end.
Aufgrund der Aussparung und des Hineinragens des einen Endes der Hülse in diese Aussparung ergibt sich für das Abgas und innerhalb des Abgases vorhandene Rußpartikel am stirnseitigen Verbindungsbereich der Welle mit der Ventilklappe ein die Welle vollständig umlaufendes Labyrinth, wodurch eine Strömung des Abgases in Richtung einer Lagerung der Welle gehemmt und ein Eintrag von Rußpartikeln in die Lagerung wird vermieden oder zumindest verringert. Somit kann eine Lebensdauer und Zuverlässigkeit des Abgasrückführungsventils mit geringem Aufwand signifikant gesteigert werden.Due to the recess and the projecting of one end of the sleeve in this recess results for the exhaust gas and within the exhaust gas soot particles present at the frontal connection region of the shaft with the valve flap, the shaft completely revolving labyrinth, whereby a flow of the exhaust gas in the direction of storage Wave inhibited and entry of soot particles in the storage is avoided or at least reduced. Thus, a life and reliability of the exhaust gas recirculation valve can be significantly increased with little effort.
