Device for swirling and mixing exhaust gases recycled in the intake duct (1) of an internal combustion engine via a recycling conduit (2). It is formed of two control flaps (3, 4) in the form of toroidal portions, mounted rotatably about axes of articulation (6, 7), said control flaps (3, 4) being displaceable in rotation between, on the one hand, a rest position in which they are retracted along the inner wall of the intake duct (1) so as to expose the entire cross-section of said duct and, on the other hand, an active position in which they are pulled towards one another so as to reduce said cross-section, and also formed of an actuator which makes it possible to control displacement of the control flaps (3, 4) between the active position and rest position thereof. |
