Abstract
An air distribution device comprises a casing (10) provided with a cylindrical wall (12) having at least one air passage opening (14, 16), a shutter (20) mounted so as to pivot with respect to an axis of rotation (X--X) and having a generally cylindrical obturation wall, which is mounted so as to movable with respect to a body of the shutter, consisting of two plates, in a direction substantially radial with respect to the axis of rotation (X--X) of the shutter by virtue of movement means (46, 48) synchronised with the rotation of the shutter, which makes it possible to move the obturation wall (24) away from the wall (12) when the shutter is in an open position (P1, P2) and bring the obturation wall (24) closer to the wall (12) of the casing when the shutter is in a closed position.
