Abstract

L'invention concerne un cylindre hydraulique émetteur comprenant un corps (2) pourvu d'un alésage interne (3) et un piston (4) apte à coulisser à l'intérieur dudit alésage interne (3) et définissant avec l'alésage interne (3) une chambre hydraulique (7) à volume variable; le cylindre hydraulique comporte un ensemble d'étanchéité comprenant : - un joint principal (15) de forme annulaire emmanché sur le piston (4) et comportant une lèvre principale (25) qui coopère dynamiquement avec une surface de contact ménagée sur l'alésage interne (3) ; et - un joint de valve (16) de forme annulaire qui est emmanché sur le piston (4) et comporte une lèvre de valve (30) qui coopère contre le piston (4) de manière à obturer un chemin de valve (27, 28) apte à mettre en communication fluidique un conduit d'alimentation en fluide et la chambre hydraulique (7) ; ladite lèvre de valve (30) étant apte à se déformer lorsque la pression à l'intérieur de la chambre hydraulique (7) descend en dessous d'un seuil de pression pour autoriser la circulation de fluide au travers du chemin de valve, du conduit (12) d'alimentation en fluide vers la chambre hydraulique (7).
