Abstract

L'invention concerne un fluide lubrifiant comprenant: 1) une quantité dominante d'une huile de viscosité propre à la lubrification; et 2) une quantité efficace d'un agent améliorant la filtrabilité ou d'un de leurs mélanges, répondant à la formule suivante: R-Z dans laquelle Z représente un groupe polaire choisi dans le groupe consistant en a) esters phosphoriques; b) amides; c) éthers; d) amino-alcools; e) amines éthoxylées ou f) leurs mélanges, et R représente une chaîne lipophile ayant 14 à 24 atomes de carbone. La présente invention concerne également l'utilisation de l'agent améliorant la filtrabilité décrit ci-dessus pour améliorer la filtrabilité d'huiles hydrauliques, ainsi qu'un procédé pour la préparation de fluides hydrauliques à filtrabilité améliorée.
