Abstract

Distributeur de direction à tiroir rotatif. Ledit distributeur comprend un tiroir rotatif entquré d'un cylindre, ces derniers comportant des arêtes d'admission et de retour d'un fluide sous pression destiné à commander un servo-moteur. Les arêtes sont disposées les unes par rapport aux autres de façon qu'en position neutre le fluide sous pression parvienne librement au raccord de retour et que, en position actionnée, le fluide passe en totalité par un étranglement entre les arêtes d'admission et de retour, selon le sens de rotation. Application aux directions assistées de véhicules automobiles.
