Abstract

L'invention concerne un transformateur hydraulique dans lequel une pluralité de déplaceurs sont guidés dans une section de déplacement. La course des déplaceurs est déterminée au moyen d'un élément de levage, l'admission et l'évacuation du fluide de pression étant commandées via un organe de commande présentant au moins trois rainures de commande. L'invention est caractérisée en ce que, ou bien la section de déplacement, ou bien l'élément de levage, ou bien l'organe de commande peuvent être entraînés, cependant que suivant l'élément qui est entraîné l'élément de levage ou la section de déplacement est monté dépourvu de réglage, et le troisième élément restant est positionné solidaire du bâti.
