摘要：
An oil pump includes a first spill passage formed on a side surface (60) of a pump chamber (58) to communicate a hydraulic pressure chamber (54) with a first high pressure discharge passage (68) when the entire hydraulic pressure chamber (54) is positioned between the first high pressure discharge passage (68) and a first low pressure discharge passage (70). Therefore, when the hydraulic pressure chamber (54) passes between the first high pressure discharge passage (68) and the first low pressure discharge passage (70), the hydraulic pressure inside the predetermined hydraulic pressure chamber (54) escapes to the first high pressure discharge passage (68) through a first spill passage (76), so a hydraulic pressure value inside the hydraulic pressure chamber (54) is maintained at the pressure value inside the first high pressure discharge passage (68). As a result, fluid is inhibited from flowing into the hydraulic pressure chamber (54) from the first high pressure discharge passage (68) through a space between inner peripheral teeth (48) and outer peripheral teeth (42).
摘要（中）：
油泵包括形成在泵室（58）的侧表面（60）上的第一溢流通道，用于在整个液压室（54）处连通液压室（54）与第一高压排放通道（68） ）位于第一高压排出通道（68）和第一低压排出通道（70）之间。 因此，当液压室54通过第一高压排出通路68和第一低压排出通路70之间时，预定的液压室54内的液压从第一高压 通过第一溢流通道（76）排出通道（68），使得液压室（54）内的液压值保持在第一高压排出通道（68）内的压力值。 结果，流体被阻止从第一高压排出通道（68）通过内周齿（48）和外周齿（42）之间的空间流入液压室（54）。
