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

Exhaust-gas recirculation device for an internal combustion engine

An actuating device including a housing that is closed by a cover in such a way that both an electric motor and a gearbox unit are completely enclosed. An internal gear segment, arranged on an output shaft in a rotationally fixed manner, is positioned on a borehole of the cover. An axle on which a double toothed gear is arranged is then mounted on the output side, an a pocket hole in the cover. This reduces the overall length, as well as the number of components and the cost.

Actuating device

The invention relates to a controllable two-way valve (), in which a valve rod () is connected in a permanent manner to at least two valve members (), the valve rod () being actuated by means of an actuator (). The housing () comprises an inlet () or outlet and two corresponding outlets (), () or inlets. According to the invention, the two valve members () correspond with at least two valve seats () and the two or more valve members () have three control surfaces (). The invention thus provides a dirt-resistant valve, which is easy to operate, has fixed valve members and does not require additional equipment. Said valve permits both the inlet to be completely blocked and the two outlets to be controlled independently of one another.
