Abstract (en)

It is disclosed a control device of a primary air flow duct and a secondary air channel within a throttle assembly for the air supply to an internal combustion engine, comprising a driving electric motor (2) and a toothed gearing transmission (5, 6, 7) for transferring the motion from said electric motor (2) to a driving shaft (A) of at least one throttle valve for the choking of said primary air flow duct and to a driving element (12, 12') of a bypass valve (18, 18') of said secondary air channel, wherein said toothed gearing transmission (5, 6, 7) is arranged to mesh with a first toothed-sector element (8) integral in rotation with said driving shaft (A) of said throttle valve of the primary air flow duct, said toothed gearing transmission (5, 6, 7) is arranged to mesh also with a second toothed-sector element (9, 9'), idle with respect to said driving shaft (A) of the throttle valve and apt to be coupled in rotation with said first toothed-sector element (8) by rigid coupling in one direction and through an elastic element (11) in the opposite direction, said second toothed-sector element (9, 9') having a driving appendix (12a, 12a') of said bypass valve (18, 18').
