Abstract

a. Vérin hydraulique-pneumatique. b. Vérin caractérisé en ce que le cylindre de positionnement est disposé coaxialement entre le cylindre de démultiplication et la chambre de cylindre plus petite et il se raccorde à cette dernière, le piston du cylindre de positionnement étant monté à coulissement axial sur la tige, et l'autre piston se trouvant, dans le cylindre de positionnement, dans une position extrême telle qu'il relie ce cylindre avec la chambre de cylindre plus petite. c. L'invention s'applique aux vérins hydrauliques-pneumatiques.
