Abstract

a. Assemblage à pignon composé d'une tige ayant un axe longitudinal et portant une crémaillère à dents hélicoïdales, cette tige et cette crémaillère étant déplaçables longitudinalement dans un carter, un pignon étant monté à rotation dans le carter, ces dents coopérant avec les dents de la crémaillère, de façon qu'à la rotation du pignon, la tige et la crémaillère se déplacent longitudinalement par rapport au carter. b. Assemblage caractérisé en ce qu'il comporte un moyen de commande qui fait tourner la crémaillère suivant l'axe longitudinal et par rapport au carter, en fonction du déplacement longitudinal de tige et de la crémaillère sous l'effet du pignon.at. Pinion assembly composed of a rod having a longitudinal axis and carrying a rack with helical teeth, this rod and this rack being movable longitudinally in a casing, a pinion being rotatably mounted in the casing, these teeth cooperating with the teeth of the rack, so that when the pinion rotates, the rod and the rack move longitudinally relative to the housing. b. Assembly characterized in that it comprises a control means which rotates the rack along the longitudinal axis and with respect to the housing, as a function of the longitudinal displacement of the rod and of the rack under the effect of the pinion.
