Abstract

L'invention concerne un filtre permettant de séparer des solides de liquides. Ce filtre comprend un corps (1) comportant un orifice d'admission (2) pour le liquide à filtrer, un premier orifice d'évacuation (34) du filtrat et un second orifice d'évacuation (15) du liquide à haute teneur en solides. Le filtre comprend également un élément de filtration (5) dont une face intérieure communique avec l'orifice d'admission (2) et une face extérieure communique avec le premier orifice d'évacuation (3). Ce filtre possède, d'autre part, un dispositif de réduction du volume (6), monté rotatif, et placé sur la face intérieure de l'élément de filtration (5).
