Device for control of an air flow in particular in a motor vehicle radiator

摘要

The ducting device comprises a frame 34 delimiting an airstream passage and at least one slat 42 mounted so that it can rotate on two crossmembers 36 of the frame, between a position in which the airstream passage is open and a position in which this passage is shut off, by means of journals 46 of this slat which are housed in bearings 56 formed in the crossmembers 36. The ducting device additionally comprises means 58 of inserting the journals 46 into the bearings 56 by moving the slat 42 at right angles to its axis of rotation Z and by forcing the orientation of this slat into an angular position that this slat never adopts between its open and shutting-off positions.
