Abstract

La présente invention concerne un vérin à course déclenchée (10), comportant un corps (12) abritant un ensemble mobile (18) comprenant un piston (20) et une tige (22), des moyens (24) pour propulser cet ensemble en réponse à une commande de déclenchement, des moyens de blocage de la tige (22) par rapport au corps de vérin (12), et un joint d'étanchéité (40) ménagé entre l'ensemble mobile (18) et le corps (12), et logé dans une première gorge annulaire (34) formée à la périphérie de l'ensemble mobile (18). Une seconde gorge annulaire (36) est ménagée sur la surface interne du corps de vérin (12), en regard de la première gorge (34), de sorte que le joint d'étanchéité (40) est logé partiellement dans la première gorge (34) et partiellement dans la seconde gorge (36) lorsque le vérin (10) se trouve dans une position non déclenchée, ce par quoi il forme les moyens de blocage de la tige (22 par rapport au corps de vérin (12).The present invention relates to a trigger stroke cylinder (10), comprising a body (12) housing a moving assembly (18) comprising a piston (20) and a rod (22), means (24) for propelling the assembly in response at a trip control, means for locking the rod (22) with respect to the cylinder body (12), and a seal (40) arranged between the moving assembly (18) and the body (12) , and housed in a first annular groove (34) formed at the periphery of the moving assembly (18). A second annular groove (36) is provided on the inner surface of the cylinder body (12), facing the first groove (34), so that the seal (40) is partially housed in the first groove ( 34) and partially in the second groove (36) when the jack (10) is in an unlocked position, whereby it forms the locking means of the rod (22 relative to the cylinder body (12).
