Abstract

Abgasrückführungsanordnung mit einem Kühler (2) und einem Ventilgehäuse (3), welches einen Einlasskanal (9) und einen Auslasskanal (8) für das dem Kühler (2) zu- und abzuleitende Abgas aufweist. In dem Ventilgehäuse (3) ist ein von einem Stellantrieb (4) angetriebener kolbenförmiger Ventilkörper (7) angeordnet. Der Ventilkörper (7) unterteilt den Innenraum (5) des Ventilgehäuses (3) in eine Einlasskammer (6) und eine Auslasskammer (8), an welche der Kühlereinlass (10) und der Kühlerauslass (11) angeschlossen sind. Der Einlasskanal (9) ist quer zur Hubrichtung (H) des Ventilkörpers (7) angeordnet, sodass er von einer umfangsseitigen Mantelfläche (13) des Ventilkörpers (7) zumindest teilweise sperrbar ist. Auf diese Weise kann über einen einzigen Ventilkörper (7) sowohl die Strömungsrichtung als auch die Strömungsmenge eingestellt werden.

Figure imgaf001
Exhaust gas recirculation arrangement comprising a radiator (2) and a valve housing (3), which has an inlet channel (9) and an outlet channel (8) for the exhaust gas to be led to and removed from the radiator (2). In the valve housing (3) of a actuator (4) driven piston-shaped valve body (7) is arranged. The valve body (7) divides the interior (5) of the valve housing (3) into an inlet chamber (6) and an outlet chamber (8) to which the radiator inlet (10) and the radiator outlet (11) are connected. The inlet channel (9) is arranged transversely to the stroke direction (H) of the valve body (7), so that it is at least partially lockable by a peripheral lateral surface (13) of the valve body (7). In this way, both the flow direction and the flow rate can be adjusted via a single valve body (7).
