Abstract: front page image
(EN)This vane pump (100) comprises a rotor (20), a plurality of vanes (30), a cam ring (40), pump chambers (41), and a center port (45). The center port (45) has: an inner opening (46) open to the inner peripheral cam surface (40a) of the cam ring (40); and an outer opening (47) open to the outer peripheral surface (40d) of the cam ring (40). The starting end (46a) of the inner opening (46) is located in front of a first imaginary line (I1) in the direction of rotation, the first imaginary line (I1) connecting the starting end (47a) of the outer opening (47) and the center (C) of rotation of the rotor (20).
(FR)L'invention concerne une pompe à palettes (100) qui comprend un rotor (20), une pluralité de palettes (30), un anneau à cames (40), des chambres de pompe (41) et un orifice central (45). L'orifice central (45) comporte : une ouverture interne (46) débouchant sur la surface (40a) de came périphérique interne de l'anneau à cames (40) ; et une ouverture externe (47) débouchant sur la surface (40d) périphérique externe de l'anneau à cames (40). L'extrémité de départ (46a) de l'ouverture interne (46) se situe devant une première ligne imaginaire (I1) dans le sens de rotation, la première ligne imaginaire (I1) reliant l'extrémité de départ (47a) de l'ouverture externe (47) et le centre (C) de rotation du rotor (20).
(JA)ベーンポンプ(100)は、ロータ(20)と、複数のベーン(30)と、カムリング(40)と、ポンプ室(41)と、センターポート(45)と、を備え、センターポート(45)は、カムリング(40)の内周カム面(40a)に開口する内側開口(46)と、カムリング(40)の外周面(40d)に開口する外側開口(47)と、を有し、内側開口(46)の始端(46a)は、外側開口(47)の始端(47a)とロータ(20)の回転中心(C)とを結ぶ第1仮想線(I1)よりも、回転方向前方に位置する。
