摘要：
在驱动旋转轴心X上配置与驱动轴(11)一体旋转的内转子(12)，具有外转子(13)和调整环(14)，该外转子(13)具有与内转子(12)的外齿(12A)啮合的内齿(13A)，可以围绕从驱动旋转轴心(X)偏心的从动轴心(Y)自由旋转，该调整环(14)可自由旋转地支撑外转子(13)。构成引导单元(G)，其利用设置在调整环(14)上的第1、第2臂部(C1、C2)和与它们滑动接触的第1、第2引导面(S 1)，一边使从动轴心(Y)围绕驱动旋转轴心(X)公转，一边使调整环(14)围绕从动轴心(Y)自转。
摘要（英）：

An oil pump provided with an inner rotor (12) rotating together with a drive shaft (11) and mounted on a driving rotation axis (X), an outer rotor (13) having inner teeth (13A) meshing with outer teeth (12A) of the inner rotor (12) and rotatable about a driven axis (Y) offset from the driving rotation axis (X), and an adjusting ring (14) for rotatably supporting the outer rotor (13). A guide means (G) is formed by first and second arm sections (C1, C2) which are provided on the adjusting ring (14) and by first and second guide surfaces (S1, S2) on which the first and second arm sections (C1, C2) slide. The guide means (G) causes the adjusting ring (14) to rotate about the driven axis (Y) while allowing the driven axis (Y) to revolve about the driving rotation axis (X).
