Title (EN) VANE PUMP
(FR) POMPE À PALETTES
(JA) ベーンポンプ
Abstract:
(EN) A vane pump (1) is provided with: a rotor (3) comprising a housing (2), a rotor main body (30) that supports a vane (4) in a pump chamber (A), and a shaft section (31) arranged inside of a cylindrical section (20B); and an oil path (L1) for supplying lubricating oil to the pump chamber (A). The oil path (L1) comprises: a first segment (203) passing through the cylindrical section (20B) in the radial direction; a second segment (310) that is arranged in the shaft section (31) and that is connected to the first segment (203); third segments (204a, 301a, 206a) that are connected to the second segment (310), that extend along the border between the housing (2) and the rotor (3), and that open into the pump chamber (A); and an opening/closing section (P1) that is arranged on the border of the first segment (203) and the second segment (310) and that cyclically opens and closes the oil path (L1) together with rotation of the rotor (3). The third segments (204a, 301a, 206a) are at least partially arranged in the rotor (3).
(FR) L'invention porte sur une pompe à palettes (1) qui comporte : un rotor (3) comprenant un boîtier (2), un corps principal (30) de rotor qui soutient une aube (4) dans une chambre (A) de pompe, et une section d'arbre (31) disposée à l'intérieur d'une section cylindrique (20B) ; et un trajet (L1) d'huile destiné à fournir de l'huile de lubrification à la chambre (A) de pompe. Le trajet (L1) d'huile comprend : un premier segment (203) traversant la section cylindrique (20B) dans la direction radiale ; un deuxième segment (310) qui est disposé dans la section d'arbre (31) et qui est relié au premier segment (203) ; des troisièmes segments (204a, 301a, 206a) qui sont reliés au deuxième segment (310), qui s'étendent le long de la bordure entre le boîtier (2) et le rotor (3), et qui débouchent dans la chambre (A) de pompe ; et une section (P1) d'ouverture/fermeture qui est disposée sur la bordure du premier segment (203) et du deuxième segment (310) et qui ouvre et ferme cycliquement le trajet (L1) d'huile avec la rotation du rotor (3). Les troisièmes segments (204a, 301a, 206a) sont au moins partiellement disposés dans le rotor (3).
(JA) ベーンポンプ(1)は、ハウジング(2)と、ポンプ室(A)においてベーン(4)を支持するロータ本体(30)と、筒部(20B)の内側に配置される軸部(31)と、を有するロータ(3)と、ポンプ室(A)に潤滑油を供給する油路(L1)と、を備える。油路(L1)は、筒部(20B)を径方向に貫通する第一区間(203)と、軸部(31)に配置され第一区間(203)に連なる第二区間(310)と、第二区間(310)に連なりハウジング(2)とロータ(3)との境界に沿って延在しポンプ室(A)に開口する第三区間(204a、301a、206a)と、第一区間(203)と第二区間(310)との境界に配置されロータ(3)の回転に伴って油路(L1)を周期的に開閉する開閉部(P1)と、を有する。第三区間(204a、301a、206a)の少なくとも一部は、ロータ(3)に配置されている。
