Abstract

Es wird eine Abgasrückführvorrichtung vorgeschlagen, welche ein Verteilerelement (14) aufweist, das korrespondierend zur Drehzahl der Nockenwelle (11) einer Verbrennungskraftmaschine (1) angetrieben wird, wobei über das Verteilerelement (14) eine fluidische Verbindung eines Abgaseinlasskanals (13) mit je einem von zur Zylinderanzahl korrespondierenden Anzahl an Abgasauslasskanälen (16) herstellbar ist.
Vorteilhafterweise kann zusätzlich zum Verteilerelement (14) ein Steuerelement (22) Verwendung finden, welches über ein Stellelement (47) bewegbar ist und mittels dessen die Freigabe der fluidischen Verbindung zwischen der Auslassöffnung (21) des Verteilerelementes (14) und den Abgasauslasskanälen (16) der Abgasrückführvorrichtung (9) im Vergleich zum Phasenwinkel der Nockenwelle (11) verschiebbar ist.

Figure imgaf001
An exhaust gas recirculation device is proposed, which has a distributor element (14) which is driven in correspondence with the rotational speed of the camshaft (11) of an internal combustion engine (1), wherein via the distributor element (14) a fluidic connection of an exhaust gas inlet channel (13) with one of each to the number of cylinders corresponding number of exhaust gas outlet channels (16) can be produced.
Advantageously, in addition to the distributor element (14), a control element (22) can be used, which is movable via an adjusting element (47) and by means of which the fluidic connection between the outlet opening (21) of the distributor element (14) and the exhaust gas outlet channels (16) can be released. the exhaust gas recirculation device (9) in relation to the phase angle of the camshaft (11) is displaceable.
