Abstract

a. Installation pour commander à volonté des embrayages de boîtes de vitesses au moyen d'un fluide sous pression. b. Installation caractérisée en ce qu'une soupape d'écoulement réagissant à l'écoulement du fluide vers les embrayages est associée à la soupape à pression différentielle, cette soupape influençant la pression qui agit sur le piston de travail de la soupape à pression différentielle. c. Dispositif applicable à la commande d'embrayages et de freins, tels que boîtes de vitesses, de véhicules d'automobiles.
