    摘要： A scroll pump includes a frame, a stationary plate scroll, an orbiting plate scroll, a non-energized type of tip seal or seals, an eccentric drive mechanism assembled to and supported by the frame and to which the orbiting plate scroll is assembled so as to be drivable by the eccentric drive mechanism in an orbit about a longitudinal axis of the pump, and an axial compliance system including a flexure. The flexure is interposed between a bearing of the eccentric drive mechanism and a flexure-locating surface of the eccentric drive mechanism. The flexure allows the orbiting plate scroll to move away from the stationary plate scroll in the case of an assembly process which would otherwise result in the tip seal(s) being too forcefully engaged with the plate of the opposing plate scroll.

    摘要翻译： 涡旋泵包括框架，固定板涡旋件，旋转板涡旋件，无通电类型的末端密封件或密封件，组装到框架并由框架支撑并且轨道板卷轴组装成的偏心驱动机构， 可以通过围绕泵的纵向轴线的轨道中的偏心驱动机构驱动，以及包括挠曲件的轴向顺应性系统。 弯曲部插入在偏心驱动机构的轴承和偏心驱动机构的挠曲定位面之间。 在组装过程的情况下，弯曲允许轨道板卷轴离开固定板涡旋件，否则将导致尖端密封件与相对的板卷轴的板太强制地接合。

    摘要： A vane pump in which oil is drawn from at least one side, in an axial direction, of a cam ring and is discharged from at least the one side, in the axial direction, of the cam ring, the vane pump including: a portion defined by a groove formed on an inner circumference surface of the cam ring, the groove extending along a circumferential direction of the inner circumference surface and arranged in a position including a middle of an axial direction width on the inner circumference surface in an oil suction section or an oil discharge section of the cam ring, the groove being formed so that a depth of the groove is constantly shallower from a mid-point, in the circumferential direction, of the groove to both ends of the groove.

    摘要： A variable displacement vane pump includes a rotor, a swingable annular cam ring receiving therein the rotor, a pump body encasing the cam ring and rotor, and a pressure plate which is disposed between an end wall of the pump body and the rotor and which includes a backup surface and a sliding surface formed with an inlet port, an outlet port and a backpressure groove. The vane pump further includes a seal member which is provided between the backup surface of the pressure plate and the end wall of the pump body, and which includes an inlet-side segment extending on the radial inner side of the inlet port and the radial outer side of the backpressure groove, and an outlet-side segment extending on the radial outer side of the outlet port.
