Title
(EN) FLUIDIC FILTER
(FR) FILTRE FLUIDIQUE
Abstract
(EN)
The present invention relates to a fluidic filter (1) for filtering a fluid, which comprises a filter housing (20) having an inlet part (21), an outlet part (23) and a housing part (22), and a filter element (10) having an inlet side and an outlet side, the filter element (10) being housed inside the housing part (22) of the filter housing (20), wherein the filter element (10) comprises a first flow passage (11) inside the filter element that extends along a longitudinal direction of the filter element (10) and is connected to the outlet part (23), and a plurality of ridges (13) extending along the longitudinal direction, wherein a plurality of second flow passages (12) respectively are formed between ridges and an inner surface (22a) of the housing part (22), allowing the fluid to flow from the inlet side of the filter element along the longitudinal direction, wherein at least a portion of the plurality of ridges (13) facing the second flow passages (12) are permeable to the fluid so as to allow passage of the fluid from the second flow passages (12) to the first flow passage (11), and wherein a tip portion (13a) of each of the plurality of ridges (13) is joined to the inner surface (22a) of the housing part (22) along a part of the tip portion (13a) of the respective ridge (13) in the longitudinal direction.

La présente invention concerne un filtre fluidique (1) destiné à filtrer un fluide, qui comprend un logement (20) de filtre ayant une partie d'entrée (21), une partie de sortie (23) et une partie de logement (22), ainsi qu'un élément de filtre (10) ayant un côté d'entrée et un côté de sortie, l'élément de filtre (10) étant logé à l'intérieur de la partie de logement (22) du logement de filtre (20). L'élément de filtre (10) comprend un premier passage d'écoulement (11) à l'intérieur de l'élément de filtre qui s'étend le long d'une direction longitudinale de l'élément de filtre (10) et qui est raccordé à la partie de sortie (23), ainsi qu'une pluralité de crêtes (13) qui s'étendent le long de la direction longitudinale. Une pluralité de seconds passages d'écoulement (12) est respectivement formée entre des crêtes et une surface interne (22a) de la partie de logement (22), permettant au fluide de s'écouler depuis le côté d'entrée de l'élément de filtre le long de la direction longitudinale. Au moins une portion de la pluralité de crêtes (13) faisant face aux seconds passages d'écoulement (12) est perméable au fluide de façon à permettre le passage du fluide depuis les seconds passages d'écoulement (12) jusqu'au premier passage d'écoulement (11), une portion de pointe (13a) de chaque crête parmi la pluralité de crêtes (13) étant reliée à la surface interne (22a) de la partie de logement (22) le long d'une partie de la portion de pointe (13a) de la crête (13) respective dans la direction longitudinale.
