Abstract
The air inlet neck, in particular for the air admission system in an internal combustion engine, comprises a mixing chamber (10) into which open a cold air admission pipe (4) and a hot air admission pipe (14). The mixing chamber (10) communicates with an outlet pipe (15) for the air of the mixing chamber. One of said pipes (4) is coaxial with the mixing chamber (10) and includes closing means constituted by flaps (5) pivotally connected to the admission pipe (4) and actuated by a cylindrical member (9) mounted to be movable between a position of complete closure of the admission pipe (4) by the flaps (5) and a position for retracting the flaps. The cylindrical member (9) constitutes means for closing the other admission pipe (14).
