摘要

A control device of a regulating valve of air (10) for a heating installation - ventilation and / or air conditioning a motor vehicle comprises a driving pinion (20) leading to a driven pinion (24) is integral in rotation of the flap, the driving pinion (20) carrying a pin (28) located in a radial direction (r1) and able to slide in a slot (30) carried by the driven pinion (24) and extending in a radial direction (r2), so that these two radial directions (r1, r2) are perpendicular to each other in a position of the end of travel of the flap, which makes it possible to lock the position of the flap.
