Abstract

L'appareil d'entraînement hydraulique décrit (10) comprend un piston hydraulique (40) séparant une chambre de travail (18) d'une première chambre (16). Le piston hydraulique (40) est sollicité en position de repos par un ressort (17) et est amené à se dépalcer sous l'action d'un courant de fluide restreignant entre la chambre de travail (18) et la première chambre (16). Pour préserver la première chambre (16) des agents contaminants, un filtre repliable (80) est disposé autour d'une tige de piston (13) du piston hydraulique (40). Le filtre (80) comprend un chapeau d'extrémité (8) présentant une ouverture centrale (91), à travers laquelle s'étend la tige de piston (13) et un élément d'extrémité opposé (98) pourvu d'une bride (95) qui sert de siège (97) pour le ressort (17). L'élément d'extrémité (98) vient se plaquer contre le piston hydraulique (40), de façon à former une jointure étanche, tandis que le chapeau d'extrémité (88) comporte un mécanisme d'étanchéité (92) autour de la périphérie de l'ouverture centrale (91), pour assurer l'étanchéité entre le chapeau d'extrémité (88) et la tige de piston (13). Si, pendant le fonctionnement de l'appareil d'entraînement hydraulique (10), le chapeau d'extrémité (88) s'engage dans une paroi opposée (15) de la première chambre (16), le filtre (80) se replie et permet au piston hydraulique (40) d'effectuer des courses complètes sans interruption, sans endommagement du filtre (80). Au cas où le filtre (80) devait se boucher, le ressort (17) siégeant sur la bride (95) permet à la bride (95) de se soulever et, ce faisant, de s'écarter du piston hydraulique (40), afin que le fluide puisse contourner le filtre (80) et assurer un fonctionnement sans interruption de l'appareil d'entraînement hydraulique (10).
