Abstract

L'invention concerne un système de réglage d'écoulement d'air (1) pour un véhicule à moteur (2), comprenant des lamelles (3) qui peuvent chacune pivoter autour d'un axe de rotation afin de régler le débit d'air à travers le système de réglage d'écoulement d'air. Selon l'invention, le système comporte au moins une cloison (8, 8') sensiblement horizontale, qui a pour effet d'au moins réduire un flux d'air secondaire (4) indésirable dirigé vers le haut. En outre, l'invention concerne un véhicule à moteur comprenant un tel système de réglage d'écoulement d'air (1). Ce système permet d'éviter ou au moins de réduire un flux d'air secondaire (4) accroissant la traînée du véhicule (2).
