Abstract

La présente invention décrit un filtre à liquide et à fluide pour moteurs à combustion interne et moteurs industriels, par exemple un filtre à huile lubrifiante, un filtre à carburant, et d'autres filtres à liquide et à fluide, comportant un guide d'écoulement (7) de liquide et de fluide au niveau de l'élément filtrant. Ce guide d'écoulement (7) est apte à guider l'écoulement de fluide passant par ce filtre et à le rendre laminaire. L'écoulement étant laminaire, l'effet de brassage sur les particules et les impuretés dans le liquide ou le fluide est notablement diminué. Ce guide d'écoulement peut être monté au niveau des parties interne et/ou externe de l'élément filtrant qui peut se présenter sous la forme d'une cartouche ou d'un élément uniquement. Si ce guide d'écoulement est monté avec un certain angle d'attaque par rapport à la base du filtre, l'écoulement peut également être tourbillonnaire.
