Abstract

L'invention concerne un dispositif de commande à fluide sous pression pour mécanismes de direction assistée, comportant un tiroir rotatif présentant sur la surface extérieure de son enveloppe cylindrique des rainures longitudinales axiales, et un manchon de commande présentant des rainures longitudinales s'étendant axialement sur la surface de son enveloppe cylindrique. Le tiroir rotatif est monté à rotation par ses extrémités dans le manchon de commande au moyen de deux roulements. Ce dispositif est destiné aux mécanismes de direction de véhicules automobiles.
