Abstract

Die Erfindung betrifft ein Abgasrückführventil (1) mit einem Flanschmodul (2), der die Anschlußverbindung zwischen dem Auslaß und dem Einlaß eines Verbrennungsmotors darstellt. Der Flanschmodul (2) ist so ausgebildet, daß ein direkter Anschluß an den Zylinderkopf des Verbrennungsmotors erfolgen kann. Im Flanschmodul (2) wird das zum Abgasrückführventil (1) strömende Abgas vom Kühlkreislauf des Verbrennungsmotors gekühlt. Zu diesem Zweck sind in dem Flanschmodul (2) Kühlkanäle mit einer Einlaßöffnung (4) und einer Auslaßöffnung (5) ausgebildet. Das Abgas wird dem Flanschmodul über eine Abgaseinlaßöffnung (6) zugeführt, die sich an einem Anschlußflansch (3) befindet.

The invention relates to an exhaust gas recirculation valve (1) with a flange module (2), which represents the connection between the outlet and the inlet of an internal combustion engine. The flange module (2) is designed so that it can be directly connected to the cylinder head of the internal combustion engine. In the flange module (2), the exhaust gas flowing to the exhaust gas recirculation valve (1) is cooled by the cooling circuit of the internal combustion engine. For this purpose, cooling channels with an inlet opening (4) and an outlet opening (5) are formed in the flange module (2). The exhaust gas is fed to the flange module via an exhaust gas inlet opening (6) which is located on a connection flange (3).
