Abstract

Le système de verrouillage pour immobiliser ou libérer le mouvement de translation d'une tige (2) d'une commande linéaire, la tige étant mobile selon une direction axiale (A) entre une première position et une deuxième position espacée d'une certaine distance selon la direction axiale de la première position, comprend deux gorges circonférentielles (2A, 2B) formées sur la tige et espacées l'une de l'autre selon la direction axiale de la dite certaine distance et une pluralité de billes (6) réparties sur la périphérie de la tige pour coopérer avec lesdites gorges circonférentielles, lesdites billes étant montées dans une cage annulaire (7, 77, 87) entourant la tige, ladite cage annulaire comprenant une première partie annulaire (7B, 77B, 87B) fixe selon la direction axiale, entourant la tige et traversée par les billes et une deuxième partie (7A, 77A, 87A) mobile par rapport à la partie annulaire fixe (7B, 77B, 87B), entourant la première partie annulaire avec les billes et agencée de manière à être entraînée en rotation ou en translation par rapport à la première partie annulaire sous l'effet d'une force axiale exercée sur la tige pour libérer le mouvement de translation de la tige.

The locking system for immobilizing or releasing the translational movement of a rod (2) of a linear control, the rod being movable in an axial direction (A) between a first position and a second position spaced a certain distance in the axial direction of the first position, comprises two circumferential grooves (2A, 2B) formed on the rod and spaced from each other in the axial direction of said certain distance and a plurality of balls (6) distributed on the periphery of the rod for cooperating with said circumferential grooves, said balls being mounted in an annular cage (7, 77, 87) surrounding the rod, said annular cage comprising a first annular portion (7B, 77B, 87B) fixed in the direction axial, surrounding the rod and traversed by the balls and a second portion (7A, 77A, 87A) movable relative to the fixed annular portion (7B, 77B, 87B), surrounding the first annular portion with the The balls are arranged to be rotated or translated relative to the first annular portion by an axial force exerted on the rod to release the translational movement of the rod.
