In Fig. 1 und 2 ist eine Vorrichtung 10 gezeigt, die zur Rückführung des Abgases einer nicht gezeigten Brennkraftmaschine dient und nachfolgend auch als Abgasrückführventil bezeichnet ist. Dieses weist ein Ventilgehäuse 11 auf, in dem ein Abgasventil 12 angeordnet ist, das den Durchlass von Abgas durch das Ventilgehäuse 11 steuert. Das Abgasventil 12 weist einen'Ventilteller 13 am unteren Ende eines Ventilschaftes 14 auf, an dem eine im Detail nicht weiter gezeigte Antriebseinrichtung 15 zur Betätigung des Ventiltellers 13 in Richtung der Längsmittelachse des Ventilschaftes 14 in Öffnungsstellung, d. h. nach unten, bzw. in Schließstellung, d. h. nach oben, angreift. Am unteren Ende des Ventilgehäuses 11 ist in dieses ein Ventilsitzring 16 eingesetzt, der eine Ventilsitzfläche 17 aufweist, an der der Ventilteller 13 in der Schließstellung mit einer zugeordneten tellerseitigen Fläche anliegt. In dieser Gestaltung stellt das Abgasventil 12 ein Hubventil dar. Bei einem anderen, nicht gezeigten Ausführungsbeispiel ist das Abgasventil 12 anders ausgebildet, z. B. als Schieberventil, und hierbei z. B. als Drehschieberventil, od. dgl.. Jede andere Ventilart kommt als Abgasventil 12 genauso gut in Betracht.1 and 2, a device 10 is shown, which is used to recirculate the exhaust gas an internal combustion engine, not shown, and subsequently also as Exhaust gas recirculation valve is called. This has a valve housing 11, in which an exhaust valve 12 is arranged, the passage of exhaust gas through the Valve housing 11 controls. The exhaust valve 12 has a valve plate 13 lower end of a valve stem 14 on which one in detail shown drive device 15 for actuating the valve plate 13 in the direction the longitudinal central axis of the valve stem 14 in the open position, d. H. downward, or in the closed position, d. H. up, attacks. At the bottom of the Valve housing 11 is inserted into a valve seat ring 16, the one Has valve seat 17 on which the valve plate 13 in the closed position an associated plate-side surface. In this design it represents Exhaust valve 12 represents a lift valve. In another, not shown Embodiment, the exhaust valve 12 is designed differently, for. B. as Slide valve, and here z. B. as a rotary slide valve, or the like. Any other Valve type is just as suitable as exhaust valve 12.

Das Ventilgehäuse 11 enthält oberhalb des Ventilsitzringes 16 einen Ventilraum 18, der mit einem Auslass 19 in Verbindung steht, über den bei geöffnetem Abgasventil 12 das in den Ventilraum 18 hineingelangende Abgas in Pfeilrichtung 20 austritt und von dort aus in üblicher Weise weitergeleitet wird. Die Zuführung des mittels des Abgasventils 12 zu steuernden Abgases erfolgt in den Zeichnungen von unten her in Pfeilrichtung 21 z. B. durch ein Gehäuse 22, das als Hohlkörper ausgebildet sein kann. Das Gehäuse 22 nimmt oben das Ventilgehäuse 11 mit Abgasventil 12 auf, wobei das Ventilgehäuse 11 und das Gehäuse 22 fest und dicht miteinander verbunden sind. Der Auslass 19 für das Abgas setzt sich bis in das Gehäuse 22 fort.The valve housing 11 contains a valve chamber above the valve seat ring 16 18, which is connected to an outlet 19, via which when open Exhaust valve 12 the exhaust gas entering the valve chamber 18 in the direction of the arrow 20 exits and is forwarded from there in the usual way.

The housing 22 takes this up Valve housing 11 with exhaust valve 12, wherein the valve housing 11 and Housing 22 are firmly and tightly connected. The outlet 19 for the Exhaust gas continues into the housing 22.

Die Vorrichtung 10 weist ferner einen der Kühlung des Ventilgehäuses 11 dienenden umlaufenden Kühlmittelkanal 30 im Inneren auf, durch den ein Kühlmittel, z. B. das Kühlwasser des Kühlkreislaufs der Brennkraftmaschine, hindurchleitbar ist. Bei bekannten Abgasrückführventilen, die mit einem inneren Kühlmittelkanal versehen sind, ist dieser Kanal als ringsum geschlossene Ringaussparung im Inneren des Ventilgehäuses 11 ausgebildet. Dies ist nur unter vergleichsweise hohen Herstellkosten für das Ventilgehäüse erreichbar und im übrigen aufwendig und kostenträchtig. Bei der Vorrichtung 10 gemäß der Erfindung ist der Kühlmittelkanal 30 statt dessen durch zwei quer zum Verlauf des Kühlmittelkanals 30, d. h. in Fig. 1 und 2 in vertikaler Richtung, zusammengesetzte Bauteile gebildet und begrenzt, von denen zumindest ein Bauteil, der hier z.

Zwischen beiden Bauteilen, hier also dem Ventilgehäuse 11 einerseits und dem Gehäuse 22 andererseits, und daher zwischen der Axialseite 31 und der Axialfläche 33, ist eine Dichtung 34 angeordnet, z. B. eine Elastomerdichtung, eine Metallsickendichtung oder ein anderer, geeigneter Dichtungsring.Between the two components, here the valve housing 11 on the one hand and the Housing 22 on the other hand, and therefore between the axial side 31 and Axial surface 33, a seal 34 is arranged, for. B. an elastomer seal, a metal bead seal or another suitable sealing ring.

Der eine Bauteil, der hier aus dem Ventilgehäuse 11 besteht, kann einen mit dem Kühlmittelkanal 30 in Verbindung stehenden Abflusskanal 35 und/oder Zuflusskanal 36 enthalten, von denen zumindest einer in einem Stutzen enthalten ist, wie dies hier für den Abflusskanal 35 vorgesehen ist. Der andere Bauteil, der hier aus dem Gehäuse 22 gebildet ist, kann einen mit dem Kühlmittelkanal 30 in Verbindung stehenden Zuflusskanal 37 und/oder Abflusskanal, z: B. einen inneren, bis zur Kanalrinne 32 führenden Kanal aufweisen. Beim gezeigten Ausführungsbeispiel enthält das Gehäuse 22 lediglich einen inneren Zuflusskanal 37, der im Gehäusemantel etwa achsparallel verläuft und in den Zuflusskanal 36 des Ventilgehäuses 11 mündet.The one component, which consists of the valve housing 11 here, can be one with the Coolant channel 30 connected drain channel 35 and / or Contain inflow channel 36, at least one of which is contained in a nozzle is, as is provided here for the drain channel 35. The other component, the is formed here from the housing 22, one with the coolant channel 30 in Connected inflow channel 37 and / or outflow channel, for example one inner channel leading to the channel channel 32.
