Abstract

L'attelage articulé (1) est prévu pour un dispositif d'étanchéité pour piston (2) pour un piston (3) qui comporte une jupe fixe (7) et une jupe glissante (12) reliées entre-elles par une liaison mécanique inter-jupes (13) pour comprimer axialement un segment continu extensible (15) sous l'action d'un ressort de jupe glissante (20), ledit attelage (1) remplaçant d'une part, la jupe fixe (7) par une jupe à liaison rotule (22) et prévoyant d'autre part, une terminaison troncosphérique de piston (21) qui coopère avec une portée troncosphérique de jupe (24) aménagée sur la jupe à liaison rotule (22) tandis que des moyens d'articulation (40) sont intercalés entre la liaison mécanique inter-jupes (13) et le piston (3) et/ou entre ladite liaison (13) et la jupe glissante (12).The articulated hitch (1) is provided for a piston sealing device (2) for a piston (3) which comprises a fixed skirt (7) and a sliding skirt (12) interconnected by an inter-mechanical connection -jupes (13) for axially compressing an extensible continuous segment (15) under the action of a sliding skirt spring (20), said hitch (1) replacing on the one hand, the fixed skirt (7) by a skirt with a ball joint connection (22) and providing, on the other hand, a truncated piston end (21) which cooperates with a trunked skirt surface (24) arranged on the ball-jointed skirt (22) while hinge means ( 40) are interposed between the inter-skirt mechanical connection (13) and the piston (3) and / or between said connection (13) and the sliding skirt (12).
