Abstract

L'invention est relative à un vérin à fluide constitué par un cylindre 1, et par un piston 25, qui est monté coulissant dans ce cylindre et est dénommé << piston principal >>. Ce piston principal 25 comprend une cavité interne 15 dans laquelle un piston auxiliaire 5 est monté coulissant et qui communique avec une chambre principale Il du vérin au moyen d'une restriction 17. Une application est la réalisation d'un vérin hydraulique possédant une fiabilité satisfaisante.
