Abstract

Bei einer Vorrichtung zum Rückführen von Abgas und zum Vorheizen des Abgasreinigers (4) einer Verbrennungskraftmaschine (1), wobei ein Abgasstrom und ein Luftstrom für die Vorheizung mittels einer Ventileinrichtung (6) gesteuert werden, ist die Ventileinrichtung (6) in einem Gehäuse (7) angeordnet ist, welches drei Abgänge (11,12,13) aufweist, wobei jeweils ein erster Abgang (11) von der Ventileinrichtung (6) mit einem zweiten (12) oder der zweite (12) mit einem dritten (13) verbindbar ist. Der erste Abgang (11) ist zum Anschluß an das Ansaugsystem (2) der Verbrennungskraftmaschine (1), der zweite Abgang (12) ist zum Anschluß an das Abgassystem (3) der Verbrennungskraftmaschine (1) und der dritte Abgang (13) zum Anschluß an eine Luftquelle (14) ausgebildet.
