Title (EN) PUMP DEVICE
(FR) DISPOSITIF DE POMPE
(JA) ポンプ装置
Abstract:
(EN) This pump device (10) comprises: a housing (30) including a fixed-side repulsive magnet (66); and an impeller (14) that is rotatably housed inside the housing (30) and that includes a movable-side repulsive magnet (56). The movable-side repulsive magnet (56) and the fixed-side repulsive magnet (66) are juxtaposed along the radial direction which is orthogonal to the rotation axis (O) of the impeller (14), and a movable-side repulsive surface (56a) and a fixed-side repulsive surface (66a) facing one another have the same polarity.
(FR) Cette invention concerne un dispositif de pompe (10) comprenant : un carter (30) contenant un aimant de répulsion côté fixe (66) ; et une turbine (14) qui est logée rotative à l'intérieur du carter (30) et qui contient un aimant de répulsion côté mobile (56). L'aimant de répulsion côté mobile (56) et l'aimant de répulsion côté fixe (66) sont juxtaposés dans le sens radial qui est perpendiculaire à l'axe de rotation (O) de la turbine (14), et une surface de répulsion côté mobile (56a) et une surface de répulsion côté fixe (66a) en regard l'une de l'autre ont la même polarité.
(JA) ポンプ装置(10)は、固定側反発磁石(66)を有するハウジング(30)と、ハウジング(30)内に回転自在に収容され、可動側反発磁石(56)を有するインペラ(14)と、を備える。可動側反発磁石(56)と固定側反発磁石(66)は、インペラ(14)の回転軸(O)に直交する径方向に沿って並び、且つ相互に対向する可動側反発面(56a)、固定側反発面(66a)の極性が同一である。
