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) A suction filter (31) in a fuel tank (2) of a vehicle for sucking fuel into an intake port (32a) of a fuel pump (32) after the fuel has been filtered is provided with: a filter screen (310) for filtering permeable fuel in a permeable wall (310f), including a bottom wall (310g) arranged to cover an inner-side space (312) in which a suction negative pressure from the intake port (32a) acts, and forms the inner-side space (312) as the permeable wall (310f) permeated by fuel and air; and a plurality of fuel stoppers (317) arranged toward a separation side separating along the bottom wall (310g) from the intake port (32a) and extending toward the separation side in the inner-side space (312).
(FR) L'invention concerne un filtre d'aspiration (31) dans un réservoir de carburant (2) d'un véhicule pour aspirer le carburant dans un orifice d'admission (32a) d'une pompe à carburant (32) une fois que le carburant a été filtré, qui comprend : un écran de filtre (310) pour filtrer un carburant perméable dans une paroi perméable (310f), comprenant une paroi de fond (310g) disposée pour recouvrir un espace côté interne (312) dans lequel une pression négative d'aspiration provenant de l'orifice d'admission (32a) agit, et forme l'espace côté interne (312) en tant que paroi perméable (310f) traversée par le carburant et l'air ; et une pluralité de bouchons de carburant (317) disposés vers un côté de séparation séparant le long de la paroi de fond (310g) depuis l'orifice d'admission (32a) et s'étendant vers le côté de séparation dans l'espace côté interne (312).
(JA) 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)に吸入させるサクションフィルタ(31)は、吸入口(32a)から吸入負圧の作用する内側空間(312)を覆って設けられており、燃料及びエアの透過する透過壁(310f)として内側空間(312)を形成している底壁(310g)を含み、透過壁(310f)における透過燃料を濾過するフィルタスクリーン(310)と、吸入口(32a)から底壁(310g)に沿って離間する離間側へ向かって複数設けられており、内側空間(312)において離間側へ向かって延びている燃料ストッパ(317)とを、備える。
