摘要： An object of the invention is to provide an electric oil pump with greatly improved operation, increased endurance, and extended service life of an Oldham's coupling connecting a drive shaft that rotates a rotor in a pump housing and a motor output shaft in a motor housing. The electric pump comprises a pump housing having a rotor and a drive shaft for rotatably supporting the rotor, and a motor housing connected to the pump housing and having an output shaft connected to the drive shaft via an Oldham's coupling. The pump housing is provided with a coupling chamber for accommodating the Oldham's coupling, and a linking channel for transporting the leaked oil from a rotor chamber accommodating the rotor of the pump housing to the coupling chamber.
摘要翻译：本发明的目的是提供一种电动油泵，其具有极大的改进的操作，增加的耐用性和延长的使用寿命，该连杆将连接驱动轴旋转在泵壳体中的转子和马达壳体中的马达输出轴之间。电动泵包括具有转子和用于可旋转地支撑转子的驱动轴的泵壳体，以及连接到泵壳体的马达壳体，并具有通过奥德姆联轴器连接到驱动轴的输出轴。泵壳体设置有用于容纳奥尔德姆联轴器的联接室和用于将泄漏的油从容纳泵壳体的转子的转子室输送到联接室的连接通道。

摘要： A device for reducing friction while maintaining characteristics identical to the pressure characteristics of a common oil pump based on provision of a plurality of discharge sources and a newly devised method of switching oil passages. The device is configured from a first discharge passage from a first rotor assembly to an engine, a first return passage that returns to an intake side of the first rotor assembly, a second discharge passage from a second rotor assembly to the engine, a second return passage that returns to an intake side of the second rotor assembly, and a pressure control valve whose valve main body is provided between a discharge port from the second rotor assembly and the first discharge passage. The first discharge passage and the second discharge passage are coupled, and a flow passage control is executed in each of: a low revolution range in a state in which only the first discharge passage and the second discharge passage are open; an intermediate revolution range in a state in which the first discharge passage and second discharge passage are open and the first return passage is closed while the second return passage is open; and a high revolution range in a state in which the second discharge passage is closed while the first discharge passage is open and the first return passage and second return passage are open.
摘要翻译：一种用于减少摩擦的装置，同时保持与基于提供多个排放源的普通油泵的压力特性相同的特性，以及新设计的切换油路的方法。该装置由从第一转子组件到发动机的第一排放通道构成，返回到第一转子组件的进气侧的第一返回通道，从第二转子组件到发动机的第二排出通道，第二回流通道返回到第二转子组件的进气侧;以及压力控制阀，其阀主体设置在从第二转子组件的排出口和第一排出通道之间。联接第一排出通道和第二排出通道，并且在只有第一排出通道和第二排出通道打开的状态下，在低转速范围内执行流路控制; 第一排出通道和第二排出通道打开的状态下的中间转速范围和第二返回通道打开时的第一返回通道关闭; 以及在第一排出通道打开并且第一返回通道和第二返回通道打开时第二排出通道关闭的状态下的高转速范围。
