Abstract

Filtre à liquide comprenant une paroi filtrante en deux éléments de porosité différente. Les deux éléments sont annulaires, plissés et disposés coaxialement de façon que la totalité du débit liquide traverse successivement les éléments 3 et 4 à partir de celui dont les pores ont la plus grande dimension. Application au filtrage des huiles de lubrification.
