Title (EN) SUCTION FILTER AND FUEL SUPPLY DEVICE
(FR) FILTRE D'ASPIRATION ET DISPOSITIF D'ALIMENTATION EN CARBURANT
(JA) サクションフィルタ及び燃料供給装置
Abstract:
(EN) This suction filter is provided with: a filter element (310) for filtering fuel inside a fuel tank (2) of a vehicle and then allowing the fuel to be taken into an intake port (32a) of a fuel pump (32), the filter element being disposed inside the fuel tank and allowing stored fuel, which is fuel stored in the fuel tank, to pass through into an inner-side space (312), thereby filtering the stored fuel; a dividing wall element (311, 2311, 3311) disposed so as to partition the inner-side space into a first space section (312a) into which flows filtered fuel, which is fuel filtered by the filter element, and a second space section (312b) into which opens the intake port for taking in filtered fuel, the dividing wall element and the filter element together enclosing the first space section, and the dividing wall element and the filter element together also enclosing the second space section; and a passage element (313) having an inflow port (313a) opened into the second space section and an outflow port (313b) subjected to intake pressure from the intake port, a flow passage (313c) for filtered fuel, which leads from the inflow port to the outflow port, being formed in the passage element.
(FR) Selon l'invention, un filtre d'aspiration comprend : un élément filtre (310) destiné à filtrer du carburant à l'intérieur d'un réservoir de carburant (2) d'un véhicule puis permettant au carburant d'être admis dans un orifice d'admission (32a) d'une pompe à carburant (32), l'élément filtre étant disposé à l'intérieur du réservoir de carburant et permettant au carburant stocké, qui est du carburant stocké dans le réservoir de carburant, de passer à travers celui-ci jusque dans un espace de côté intérieur (312), ce qui filtre le carburant stocké ; un élément cloison (311, 2311, 3311) situé de façon à partager l'espace de côté intérieur en une première section d'espace (312a) dans laquelle s'écoule le carburant filtré, qui est du carburant filtré par l'élément filtre, et une deuxième section d'espace (312b) dans laquelle s'ouvre l'orifice d'admission permettant d'admettre le carburant filtré, l'élément cloison et l'élément filtre enfermant ensemble la première section d'espace, et l'élément cloison et l'élément filtre enfermant aussi ensemble la deuxième section d'espace ; et un élément passage (313) comportant un orifice d'entrée (313a) ouvert dans la deuxième section d'espace et un orifice de sortie (313b) soumis à une pression d'admission de l'orifice d'admission, un passage d'écoulement (313c) pour du carburant filtré, qui conduit de l'orifice d'entrée à l'orifice de sortie, étant formé dans l'élément passage.
(JA)  サクションフィルタは、車両の燃料タンク(2)内において燃料を濾過してから燃料ポンプ(32)の吸入口(32a)へ吸入させて、燃料タンク内に配置され、燃料タンク内に貯留された燃料である貯留燃料を内側空間(312)へ通過させることにより、貯留燃料を濾過するフィルタエレメント(310)と、フィルタエレメントにより濾過された燃料である濾過燃料の流入する第一空間部(312a)と、濾過燃料を吸入する吸入口の開口した第二空間部(312b)とに、内側空間を仕切って配置され、フィルタエレメントと共同して第一空間部を囲み、且つフィルタエレメントと共同して第二空間部を囲む隔壁エレメント(311,2311,3311)と、第二空間部に開口した流入口(313a)、並びに吸入口により吸入圧力が作用する流出口(313b)を有し、流入口から流出口に向かう濾過燃料の流通通路(313c)を形成している通路エレメント(313)とを、備える。
