Abstract
A mixing valve of an exhaust-gas recirculation device of an internal combustion engine of a motor vehicle includes an intake flap and an exhaust-gas flap coupled rigidly to one another via a coupling rod. During driving of the exhaust-gas flap, the intake flap is first pivoted in the opposite direction via the coupling rod. The exhaust-gas flap and intake flap are pivoted in the same direction only above a provided pivoting angle.

1-6. (canceled)
A mixing valve (6) of an internal combustion engine (1) of a motor vehicle, comprising:
- an intake duct (4);
- an exhaust duct (5), wherein, in a first position, the exhaust duct (5) is closed and the intake duct (4) is open;
- a common collecting duct (7) into which the intake duct (4) and exhaust duct (5) commonly issue;
- an intake flap (10) arranged in the intake duct (4) and having an intake flap control lever (12);
- an exhaust flap (11) arranged in the exhaust duct (5) and having an exhaust flap control lever (13);
- a drive device (8) driving the intake flap (10) and the exhaust flap (11);
- and
- a coupling device (14) coupled to the exhaust flap control lever (13) and to the intake flap control lever (12),
- wherein the coupling device (14) has a coupling rod (15) for direct transmission of the movements of the intake flap control lever (12) and the exhaust flap control lever (13), and, in the first position, the exhaust flap control lever (13) and the coupling rod (15) are arranged at an obtuse angle relative to one another, and the intake flap control lever (12) and the coupling rod (15) are arranged at an acute angle relative to one another.
