Abstract

Pour déterminer la position du piston, on forme une capacité variable à l'intérieur du dispositif. Toutes les électrodes sont bloquées en translation relative dans le meme élément. Les électrodes 8 et 11 sont tubulaires et montées dans la tige de piston 3 d'un amortisseur. Un tube 13 en matière plastique fixé au fond 24 du cylindre 1 plonge dans l'espace 12 entre les électrodes et y remplace l'huile isolante en fonction de la course de l'amortisseur.
