Abstract
In a mixing valve for an internal combustion engine of a motor vehicle, the distance between pivot axes of two flaps is smaller than the diameter of the largest flap. The flaps are also connected to a single drive device. The drive device ensures a collision-free coupling of the movements of the flaps.

1-10. (canceled)
A mixing valve (6) of an internal combustion engine (1) of a motor vehicle, comprising:
- an intake duct (4);
- an exhaust-gas recirculation duct (5);
- a first flap (10), having a pivot axis (12), arranged in the intake duct (4);
- a second flap (11), having a pivot axis (13), arranged in the exhaust-gas recirculation duct (5), wherein the intake duct (4) and the exhaust-gas recirculation duct (5) issue into a common collecting duct (7);
- and
- a drive device (8) configured to drive the first and second flaps (10, 11);
- wherein a spacing between the pivot axes (12, 13) of the first and second flaps (10, 11) is smaller than the diameter of the first flap (10), and pivoting movements of the first and second flaps (10, 11) are coupled in a collision-free manner.
