Abstract

Die Erfindung betrifft ein Steuerventil zur Abgasrückführung in eine Luftansaug- bzw. Kraftstoffaufbereitungsanlage einer Verbrennungskraftmaschine. Das Steuerventil weist ein Ventilgehäuse auf, in dem ein mit einem Auslaß der Verbrennungskraftmaschine verbindbarer Abgaseinlaß, eine mit der Luftansaug- bzw. Kraftstoffaufbereitungsanlage verbindbare erste Kammer und eine zweite Kammer ausgebildet ist, wobei die erste Kammer und die zweite Kammer jeweils eine in den Abgaseinlaß mündende Öffnung aufweisen. Im Ventilgehäuse ist ein sich durch die Öffnungen erstreckender Ventilkörper verschieblich gelagert, an dem zwei Ventilelemente zum Verschließen der Öffnungen vorgesehen sind. Der Ventilkörper kann zwischen einer Freigabestellung und einer Schließstellung zum Öffnen und Schließen mindestens einer der Öffnungen aktiviert werden. Im Ventilkörper ist mindestens ein Druckausgleichskanal ausgebildet, der die beiden Kammern im Ventilgehäuse miteinander verbindet.

The invention relates to a control valve for exhaust gas recirculation in an air intake or fuel processing system of an internal combustion engine. The control valve has a valve housing in which an exhaust gas inlet which can be connected to an outlet of the internal combustion engine, a first chamber which can be connected to the air intake or fuel processing system and a second chamber are formed, the first chamber and the second chamber each opening into the exhaust gas inlet Have opening. In the valve housing, a valve body extending through the openings is slidably mounted, on which two valve elements are provided for closing the openings. The valve body can be activated between a release position and a closed position for opening and closing at least one of the openings. At least one pressure compensation channel is formed in the valve body, which connects the two chambers in the valve housing to one another.
