Abstract

L'objet de l'invention se rattache au secteur technique des moteurs hydrauliques ou pneumatiques. Le vérin est caractérisé en ce qu'il comprend deux chambres distinctes de mise en pression, reliées respectivement à des distributeurs classiques et séparées par un ensemble de deux pistons coulissant l'un par rapport à l'autre; le grand piston coulissant dans le cylindre est solidaire d'une tige de commande de l'organe à manoeuvrer, tandis que le petit piston coulissant dans l'autre peut se déplacer de manière contrôlée sur une tige épaulée solidaire de l'autre tige; des canaux, réalisés sur le petit piston et sur les tiges porte-pistons, assurant ou non le transfert du fluide d'une chambre dans l'autre suivant les conditions de fonctionnement, en combinaison avec un amortisseur coulissant élastiquement sur la tige de commande, entre le grand piston et un flasque du vérin. L'invention s'applique notamment à la commande des portes de véhicules.
