Abstract

L'invention concerne un dispositif piston-cylindre, notamment destiné à un cylindre émetteur d'un système d'actionnement d'embrayage dans un véhicule à moteur, comportant un piston logé axialement mobile dans un cylindre conçu en tant que carter et un système de détection disposé sur le carter et coopérant avec un composant de détection fixé sur ou dans le piston. Sur un dispositif piston-cylindre présentant une sécurité anti-rotation particulièrement simple, le piston comporte, à proximité du composant de détection, une nervure de guidage s'étendant axialement et s'encastrant dans une rainure de guidage axiale créée sur une paroi intérieure du carter.
