The control includes a primary motorised lever (10) rotated by toothed wheels (14,16) about an axis (12), between two opening positions (PO,PO') via an intermediate position of closure (PF). This lever is coupled by a deformable rod (26) to a secondary lever (24) which rotates the flap (20) about its pivot axis (22). The primary lever (10) has on each side of the closure position an intermediate position (PI,PI') at which the flap is already closed. The distance between the intermediate positions represents a backlash throughout which the flap remains closed with the rod under strain. |
