Abstract

Appareil de filtration à étages multiples, servant à détecter les substances contaminantes contenues dans un lubrifiant et dans une huile servant de fluide moteur hydraulique. Cet appareil comprend un fond dont la partie inférieure comporte un réservoir d'huile et dont la partie latérale présente une ouverture en communication avec l'air à l'extérieur; un ensemble d'éléments présentant chacun un trou en communication avec le réservoir d'huile et reliés au fond; une tête possédant un orifice d'admission pour l'huile et reliée aux éléments, dans une configuration à plusieurs étages; et un ensemble de filtres disposés en série, présentant différentes granulométries de filtrage. Une ouverture est formée dans la paroi latérale de chaque élément, de manière à être en communication avec le trou qu'il comporte, et un récepteur d'huile en communication avec ledit trou est introduit dans chaque élément. Il est ainsi possible de collecter, en une seule étape de filtrage et en fonction de leur taille, différents types de particules contaminantes de granulométries différentes, et de séparer de l'huile ne contenant aucune particule contaminante dont la granulométrie dépasse un niveau déterminé. On peut produire en une seule opération de filtrage plusieurs types d'huiles ainsi séparées.
