Abstract

Die Erfindung betrifft eine Vorrichtung zur Rückführung des Abgases einer Brennkraftmaschine, mit einem in einem Ventilgehäuse (11) angeordneten, den Durchlass von Abgas steuernden Abgasventil (12) und mit mindestens einem der Kühlung des Ventilgehäuses (11) dienenden, umlaufenden Kühlmittelkanal (30), durch den ein Kühlmittel hindurchleitbar ist. Der Kühlmittelkanal (30) ist durch zwei quer zum Kanalverlauf zusammengesetzte Bauteile (11,22) gebildet und begrenzt, von denen zumindest ein Bauteil (11) auf einer Axialseite (31) eine eingetiefte und zu dieser Axialseite (31) offene Kanalrinne (32) als Teil des Kühlmittelkanals (30) aufweist und der andere Bauteil (22) mit einer Axialfläche (33) an die die offene Kanalrinne (32) enthaltende Axialseite (31) des einen Bauteils (11) unter Komplettierung und Schließung des Kühlmittelkanals (30) angesetzt ist (Fig. 1).

The invention relates to a device for recirculating the exhaust gas of an internal combustion engine, having an exhaust gas valve (12) arranged in a valve housing (11) and with at least one circulating coolant channel (30) serving to cool the valve housing (11). through which a coolant can be passed. The coolant channel (30) is formed and bounded by two components (11, 22) which are composed transversely to the channel, of which at least one component (11) has on an axial side (31) a channel channel (32) which is recessed and open to this axial side (31). as part of the coolant channel (30), and the other component (22) having an axial surface (33) attached to the axial side (31) of the one component (11) containing the open channel groove (32) with completion and closure of the coolant channel (30) is (Fig. 1).
