Abstract
a. Vérin hydraulique ou pneumatique à frottement réduit b. Vérin caractérisé en ce que le piston peut être sollicité sur un côté avec le fluide de travail, tandis que, sur l'autre côté, agit le fluide de lubrification qui pénètre dans la chambre de cylindre sous une pression réglée, la contrepression ainsi produite étant inférieure à la force axiale du piston sollicité par le fuide de travail, mais cependant supérieure à la force axiale du piston non sollicité par le fluide de travail. c. L'invention s'applique notamment à des vérins alimentés à l'hélium.
