Abstract

Direction assistée à servopompe et à piston de travail subdivisant le boîtier en deux chambres sous pression et supportant une denture qui fait tourner l'axe de levier de direction; un écrou de direction rotatif dans le piston de travail actionne par un taquet un distributeur de commande disposé transversalement et de manière excentrée dans le piston de travail et dont une rotation du volant de direction provoque le déplacement du tiroir, ce dernier étant soumis à un rappel en position centrèe. Un ressort à tige de flexion 24 assure le rappel en position centrée du tiroir du distributeur 17. Application aux directions assistées à commande hydraulique
