| description | To provide an oil pump capable of actualizing smooth rotation of a pump rotor by stably reducing the rotation resistance of the pump rotor.SOLUTION: The oil pump includes housings 11, 40 having a pump chamber 12 storing an inner rotor 15 and an outer rotor 16. In the housing 40, suction ports 41a, 41b, and discharge ports 42a, 42b are formed. The suction ports 41a, 41b are formed on both sides across the pump chamber 12, and the discharge ports 42a, 42b are a first discharge port 42a to which a discharge passage is connected and a second discharge port 42b on the opposite side to the first discharge port 42a across the pump chamber 12. The suction port 41b on the same side as the second discharge port 42b has a first recessed part 47 extending to the outside of the outer periphery of the outer rotor 16, and the first recessed part 47 is formed in the housings 11, 40 along the outer periphery of the outer rotor 16.SELECTED DRAWING: Figure 1
【課題】ポンプロータの回転抵抗を安定的に低減し、ポンプロータの円滑な回転を実現できるオイルポンプを提供する。【解決手段】インナロータ１５及びアウタロータ１６を収容するポンプ室１２を有するハウジング１１，４０と、を備え、ハウジング４０には、吸入ポート４１ａ、４１ｂと、吐出ポート４２ａ，４２ｂとが形成され、吸入ポート４１ａ，４１ｂは、ポンプ室１２を挟んで両側に形成されており、吐出ポート４２ａ，４２ｂは、吐出通路が接続される第１吐出ポート４２ａと、ポンプ室１２を挟んで第１吐出ポート４２ａとは反対の側の第２吐出ポート４２ｂとを有しており、第２吐出ポート４２ｂと同じ側にある吸入ポート４１ｂは、アウタロータ１６の外周の外方まで延設された第１凹部４７を有し、第１凹部４７はハウジング１１，４０においてアウタロータ１６の外周に沿って形成されている。【選択図】図１ |
