Abstract

An exhaust-gas recirculation device includes a distributor element (14) driven corresponding to the rotational speed of the camshaft (11) of an internal combustion engine (1), wherein, via the distributor element (14), a fluidic connection can be established from an exhaust-gas inlet channel (13) to respectively one exhaust-gas outlet channel (16) of a plurality of exhaust-gas outlet channels (16) corresponding in number to the cylinders. Advantageously, apart from the distributor element (14), use can be made of a control element (22) which is movable via an actuator (47) and by which clearing of the fluidic connection between the outlet opening (21) of the distributor element (14) and the exhaust-gas outlet channels (16) of the exhaust gas recirculation device (9) can be shifted in comparison to the phase angle of the camshaft (11).
