一种用于降低流体泵附加损失的装置是由通过离合器元件使动力供给驱动轴与驱动泵元件相连接实现的。离合器元件啮合驱动泵元件并摩擦地啮合驱动轴，在达到或者超过预定液压时，离合器元件释放驱动轴，从而驱动轴在离合器元件内部转动，因而暂停泵吸作用。当液压下降到低于预定液压时，离合器元件再次啮合驱动轴从而重新开始泵吸作用。

6	Internal gear pump	US14127892	2012-12-26	US09091263B2	2015-07-28	Masato Uozumi; Toshiyuki Kosuge
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<1 is satisfied, cusps s are not formed at opposite edges of each addendum of the inner rotor 2. K = C 6 · n + 2 n + 1 · n + 2 3 ⁢ n ⁢ ⁢ ( b 2 - e 2 ) < 1 ( 1 )

PROBLEM TO BE SOLVED: To create a tooth profile of an inner rotor 2 of an internal gear pump without generating a cusp s at a tooth tip 2a thereof.SOLUTION: In an internal gear pump 9, a pump rotor 1 is configured by combining an inner rotor with an outer rotor having (n+1) teeth, wherein, with a base circle diameter denoted as A, a rolling circle radius as b, a trajectory circle diameter as C, and an eccentric amount as e (mm), the rolling circle is rolled on the base circle without slipping to draw a trochoid curve T by a trajectory of a fixed point separated from a center of the rolling circle by e, and wherein an envelope of a group of trajectory circles each having a center on the trochoid curve T is used as a tooth profile of the inner rotor 2 having n teeth. The tooth profile curve of the inner rotor satisfies expression (1). Since K<1 is satisfied, no cusp s is generated at both ends of tooth tips of the tooth profile of the inner rotor 2.

9	Variable displacement vane pump	US12773631	2010-05-04	US08602749B2	2013-12-10	Georg Zwickler; Herbert Schmitz
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.

11	Device for controlling parasitic losses in a fluid pump	US11110476	2005-04-20	US20050249622A1	2005-11-10	Michael Sefcik
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.
