    摘要： A variable displacement vane pump has a pressure controlled valve moveable between first and at least second valve positions based on an output pressure of the pressurized lubricant delivered through the outlet. The pressure controlled valve provides an integrated fail safe function to the pump when an electrical valve fails. The pressure controlled valve is inactive in the first position for an output pressure below a threshold level, allowing an electrical valve (current, solenoid, pulse width modulation (PWM) valve) to selectively control pressure in the control chamber under normal operation of the pump. In fail safe regulation mode, the electrical valve function is disabled and the pressure controlled valve is active in its second position, controlling pressure in the control chamber. Channels and vents in the pump can be opened and closed based on selective movement of the valve when the outlet pressure is at or above a threshold level.

    摘要翻译： 可变排量叶片泵具有压力控制阀，其基于通过出口输送的加压润滑剂的输出压力在第一阀位位置和至少第二阀位置之间移动。 当电动阀故障时，压力控制阀为泵提供了一个集成的故障安全功能。 压力控制阀在第一位置处无效，输出压力低于阈值水平，允许电动阀（电流，螺线管，脉宽调制（PWM）阀）在泵的正常运行下选择性地控制控制室中的压力 。 在故障安全调节模式下，电气阀功能被禁用，压力控制阀在其第二位置处于活动状态，从而控制控制室中的压力。 当出口压力等于或高于阈值水平时，可以基于阀的选择性运动来打开和关闭泵中的通道和通风口。

    摘要： A rotary fluid pressure device includes a housing section defining an inlet port and a return port. A valving assembly is in fluid communication with the inlet port and the return port. A first fluid meter defines a plurality of volume chambers that are in fluid communication with the valving assembly. A second fluid meter defines a second plurality of volume chambers in selective fluid communication with the valving assembly. A drive assembly is engaged with the first fluid meter and the second fluid meter. The drive assembly has a drive shaft and a drive collar. The drive shaft has a first axial end portion engaged with the first fluid meter and an oppositely disposed second axial end portion, the drive collar is removably coupled to the second axial end portion of the drive shaft. The drive collar is engaged with the second fluid meter.

    摘要： An eccentric movable vane pump, including a cylinder body (1), a first rotor (2), second rotors (4), and movable vanes (21). The first rotor (2) is eccentrically disposed with the second rotors (4). The number of the movable vanes (21) is greater than or equal to 2. One end of each of the movable vanes (21) is rotatably connected to the first rotor (2), and the other ends of the movable vanes (21) are rotatably connected to the second rotors (4). The first rotor (2) is disposed on a main shaft (11). The cylinder body (1) is provided with a fluid inlet (61) and a fluid outlet (62) respectively corresponding to an expansion area and a compression area of a space between adjacent movable vanes (21). The pump has advantages of a simple structure, high efficiency, low cost, multiple operation conditions, high stability, and a long service life, can operate in a high-speed range and an ultra-high speed range without being sealed by an elastic device, and has a small radial impact in operation.
