Title (EN) CYLINDRICAL FILTER
(FR) FILTRE CYLINDRIQUE
Abstract:
(EN) To improve particle capturing performance and classification filtering capacity of a cylindrical filter. A cylindrical filter includes a hollow cylindrical filter body configured by suitably combining a plurality of cylindrical first filter sections having mutually different inner diameters, each first filter section including a glass fiber as a major component, and a plurality of cylindrical second filter sections having mutually different inner diameters, each second filter section including a resin fiber as a major component, with each other. The first filter sections and the second filter sections are disposed in a concentrically superimposed manner and alternately arranged in a radial direction relative to each other. The cylindrical filter further includes a pair of seal members fixedly provided on the opposite axial ends of the first and second filter sections.
(FR) L'invention vise à améliorer les performances de capture de particules et la capacité de filtration et de classification d'un filtre cylindrique. A cet effet, l'invention porte sur un filtre cylindrique qui comprend un corps de filtre cylindrique creux configuré par combinaison appropriée d'une pluralité de premières sections de filtre cylindriques présentant des diamètres internes mutuellement différents, chaque première section de filtre comprenant de la fibre de verre en tant que composant principal, et une pluralité de secondes sections de filtre cylindriques présentant des diamètres internes mutuellement différents, chaque seconde section de filtre comprenant une fibre de résine en tant que composant principal, entre elles. Les premières sections de filtre et les secondes sections de filtre sont disposées d'une manière superposée de façon concentrique et sont agencées en alternance dans une direction radiale les unes par rapport aux autres. Le filtre cylindrique comprend en outre une paire d'éléments d'étanchéité disposés de façon fixe sur les extrémités axiales opposées des premières et secondes sections de filtre.
