    摘要： A rotary fluid pump, comprising: a housing defining a circular cylindrical pumping chamber; at least one blade positioning ring mounted for rotation around the periphery of the pumping chamber; an eccentrically disposed drive shaft for slidably engaging and rotating a blade mechanism in the pumping chamber; means enabling the blade mechanism to rotatably drive the at least one blade positioning ring and accommodate the eccentric rotation of the blade; and, fluid intake and exhaust ports. A first embodiment further comprises: a stacked pair of blade positioning rings mounted for independent rotation around the periphery of the pumping chamber; a blade assembly pivotably mounted at each end to a different one of the rings; and, slidably interfitting structure in the blade assembly for accommodating the relative movement of the ends of the blade assembly during the eccentric rotation. A second embodiment comprises structure effecting sequential engagement and disengagement of the blade to preselected positions on the ring during rotation, which together with the sliding movement between the blade and the drive shaft, changes the effective length of the blade during the eccentric rotation.

    摘要翻译： 一种旋转流体泵，包括：限定圆柱形泵送室的壳体; 至少一个叶片定位环安装成围绕所述泵送室的周边旋转; 偏心地布置的驱动轴，用于可滑动地接合和旋转泵送室中的叶片机构; 使得所述刀片机构能够旋转地驱动所述至少一个刀片定位环并适应所述刀片的偏心旋转; 和流体进出口。 第一实施例还包括：叠置的一对叶片定位环，其安装成围绕泵送室的周边独立旋转; 刀片组件，其可枢转地安装在每个端部的不同的一个环上; 以及在叶片组件中可滑动地相互连接的结构，用于在偏心旋转期间容纳叶片组件的端部的相对运动。 第二实施例包括在旋转期间叶片顺序地接合和分离到环上的预选位置的结构，其随着叶片和驱动轴之间的滑动运动在偏心旋转期间改变叶片的有效长度。

    摘要： A vane pump comprising a cylindrical pump chamber, vanes adapted to rotate within the pump chamber, and a drive rotor arranged eccentrically with respect to the center of rotation of the vanes, such vane pump being formed with through holes in portions of opposite end walls of the drive rotor which are in spaced juxtaposed relationship with side end faces of each vane, such through holes being connected to a line for supplying therethrough a portion of the fluid discharged by the vane pump. During operation of the vane pump, the portion of the fluid discharged by the pump and supplied through the line is ejected through the through openings against the side end faces of the vanes so as to avoid collision between the end walls of the drive rotor and the side end faces of the vanes whereby the service life of the vane pump can be increased.
