摘要： A variable displacement vane pump includes, but is not limited to inlet and outlet ports in a pump body, a drive shaft rotatably mounted in the pump body, a rotor driven by the drive shaft and radially extending vanes slidably disposed in the rotor. A slide is pivotally disposed on a pivot and has a central axis eccentric to the axis of the rotor. Chambers are defined by the rotor, the vanes and the slide that are successively connected to the inlet and outlet ports. A resilient member is pivotally engaged with the slide and acts on the slide to urge the slide in one direction.

摘要： In an internal gear pump 9, a diameter of a base circle is set to A mm, a radius of a rolling circle is set to b mm, a diameter of a locus circle is set to C mm, and an amount of eccentricity is set to e mm. A trochoidal curve T is drawn by rolling the rolling circle along the base circle without slipping and by using a locus of a fixed point distant from a center of the rolling circle by e. A tooth profile of an inner rotor 2 having n teeth is formed based on an envelope of a group of the locus circles each having a center on the trochoidal curve T. A pump rotor 1 is formed by combining the inner rotor with an outer rotor having (n+1) teeth. A tooth-profile curve of the inner rotor satisfies the following expression (1). Because K

摘要： A device for reducing parasitic loss of a fluid pump is accomplished by connecting the power supply driveshaft to the drive pump element through a clutch element. The clutch element engages the drive pump element and frictionally engages the driveshaft so that at or above a predetermined fluid pressure, the clutch element releases the driveshaft so the driveshaft rotates within the clutch element thereby halting the pumping action of the pump. When the fluid pressure drops below a predetermined fluid pressure, the clutch element reengages the driveshaft to resume the pumping action.
摘要翻译： 用于减少流体泵的寄生损耗的装置通过将电源驱动轴通过离合器元件连接到驱动泵元件来实现。 离合器元件接合驱动泵元件并摩擦地接合驱动轴，使得在等于或高于预定流体压力时，离合器元件释放驱动轴，使得驱动轴在离合器元件内旋转，从而停止泵的泵送动作。 当流体压力低于预定流体压力时，离合器元件重新接合驱动轴以恢复泵送动作。
