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.
