Abstract

L'invention concerne un distributeur à tiroir rotatif pour mécanismes de direction assistée de véhicules automobiles. Ledit distributeur comprend un tiroir 4 entouré d'un cylindre 6, ces derniers 4, 6 comportant des arêtes de commande d'admission et de retour d'un fluide sous pression destiné à commander un servomoteur 8. Des arêtes supplémentaires 11 de commande du débit du fluide sont situées dans un second plan interne, entre un palier lisse 14 et la paroi interne du tiroir 4. Ce palier 14 présente des encoches longitudinales 13 ouvertes vers sa face orientée vers un raccord de sortie, ces encoches 13 coopérant avec lesdites arêtes supplémentaires 11 afin de provoquer un étranglement du débit du fluide. Application aux directions assistées de véhicules automobiles.
