Ventilation system aerator for motor vehicle, has two opposite deflectors cooperating to deviate part of air flow from neighborhood of conduit wall towards center of conduit on closure range

摘要

The aerator has a conduit (2) delimited by a wall (3), and a flow orientation grid (4) arranged at an end of the aerator. Two opposite deflectors (5, 6) arranged at the conduit, are movable on a closure range between opening and the closing positions respectively. The deflectors cooperate to deviate a part of the air flow from a neighborhood of a part of the wall, towards the center of the conduit on the closure range.
