Abstract

Distributeur à commande dynamique, fermé en position centrale, pour direction assistée. Les valves d'admission 422 et d'échappement 424 qui coopèrent avec les chambres de travail du servo-moteur sont des clapets, que le tringlage de direction commande par l'intermédiaire de ressorts agissant sur les balanciers 464. Des doigts de butée 468 annulent l'action de ces ressorts quand l'angle de braquage est supérieur à une certaine valeur. Application notamment aux directions assistées des automobiles de tourisme.
