Title (EN) PUMP DEVICE
(FR) DISPOSITIF DE POMPE
(JA) ポンプ装置
Abstract:
(EN) This pump device 1 comprises a motor unit 10 having a shaft 5 arranged along a central axis J extending in the axial direction, a pump unit 30 which is positioned to one side in the axial direction of the motor unit 10 and which is driven by the motor unit 10 through the shaft 5 and discharges oil, and an inverter circuit 50 which is positioned radially outwards of the motor unit 10. The motor unit 10 comprises a rotor 11 which can rotate around the shaft 5, a stator 15 which is arranged opposite of the rotor 11, and a housing 21 which houses the rotor 11 and the stator 15. The housing 21 has a heat sink 60 on the outside surface, the heat sink 60 has a first flow path 61 that passes oil pumped from the pump unit 30, and the inverter circuit 50 is in thermal contact with the heat sink 60.
(FR) La présente invention concerne un dispositif de pompe (1) qui comprend une unité de moteur (10) ayant un arbre (5) disposé le long d'un axe central (J) s'étendant dans la direction axiale, une unité de pompe (30) qui est positionnée sur un côté dans la direction axiale de l'unité de moteur (10) et qui est entraînée par l'unité de moteur (10) par le biais de l'arbre (5) et évacue l'huile, et un circuit onduleur (50) qui est positionné radialement vers l'extérieur de l'unité de moteur (10). L'unité de moteur (10) comprend un rotor (11) qui peut tourner autour de l'arbre (5), un stator (15) qui est disposé à l'opposé du rotor (11), et un boîtier (21) qui reçoit le rotor (11) et le stator (15). Un dissipateur thermique (60) se trouve sur la surface externe du boîtier (21), le dissipateur thermique (60) comporte un premier chemin d'écoulement (61) qui laisse passer l'huile pompée à partir de l'unité de pompe (30), et le circuit onduleur (50) est en contact thermique avec le dissipateur thermique (60).
(JA) ポンプ装置1は、軸方向に延びる中心軸Jに沿って配置されたシャフト5を有するモータ部10と、モータ部10の軸方向一方側に位置し、モータ部10によってシャフト5を介して駆動されてオイルを吐出するポンプ部30と、モータ部10の径方向外側に位置するインバータ回路50と、を有し、モータ部10は、シャフト5の周囲において回転可能なロータ11と、ロータ11と対向して配置されたステータ15と、ロータ11及びステータ15を収容するハウジング21と、を有し、ハウジング21は、外側面にヒートシンク60を有し、ヒートシンク60は、ポンプ部30から送出されたオイルを流す第1流路61を有し、インバータ回路50は、ヒートシンク60と熱的に接触する。
