    • 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.
    • 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。

    • The present invention provides an oil pump in which eroding of the inside of the pump due to cavitation and erosion is prevented by minimizing the pressure change in a fluid when inter-tooth spaces formed by an inner rotor and an outer rotor transport the fluid from the intake port to the discharge port. The oil pump comprises: an inner rotor; an outer rotor; an intake port; a discharge port; a transfer side partition part formed between a terminal end of the intake port and a leading end of the discharge port; and a shallow groove which is formed in the transfer side partition part, and which communicates with the discharge port but does not communicate with the intake port. The shallow groove does not intersect with the cell on the transfer side partition part, and is positioned farther inward than the circular locus of the gear bottom parts of the inner rotor. The shallow groove communicates with the cell through a side clearance between the transfer side partition part and the rotor side surfaces of the inner rotor and the outer rotor.
    • 本发明提供一种油泵,其中,通过使由内转子和外转子形成的齿间间隙使流体从 进气口到排放口。 油泵包括:内转子; 外转子 进气口 排放口; 形成在所述进气口的末端和所述排出口的前端之间的传送侧分隔部; 以及形成在传送侧分隔部中并且与排出口连通但不与进气口连通的浅槽。 浅槽不与转印侧分隔部上的单元相交,并且位于比内转子的齿轮底部的圆形轨迹更靠内侧。 浅槽通过转印侧分隔部与内转子和外转子的转子侧面之间的侧间隙与电池连通。
