摘要： An assembly for filtering a fluid includes a first rotatable shaft with a first set of splines. The first rotatable shaft has an internal cavity containing the fluid. Also included is a second rotatable shaft with a second set of splines mated to the first set of splines. The second rotatable shaft includes at least a portion of a supply hole. The first rotatable shaft and the second rotatable shaft are configured to convey the fluid from the internal cavity through a tight clearance between the first set of splines and the second set of splines, to filter the fluid, and then out the supply hole.

摘要： A fluid pump with a rotary impeller is disclosed which comprises an electromagnetically-driven, bearing-free, seal-free rotary impeller levitated by localized opposed, magnetic forces and by fluid forces, or by localized opposed magnetic forces only. Levitation by localized opposed magnetic forces alone or by a combination of magnetic and fluid forces of an impeller driven by electromagnetic forces eliminates the need for bearings and seals in the driving mechanism. This avoids the heat build-up and leakage associated with other pumping mechanisms, which can be of importance in pumping of physiological fluids such as blood. The levitating forces of the present invention are applied both axially and radially with respect to the impeller. The magnetic forces are provided by a combination of diamagnets or solenoids, opposed by permanent magnets, solenoids or electromagnets. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized forces are apparent.
摘要翻译：公开了一种具有旋转叶轮的流体泵，其包括由局部相对的磁力和流体力或仅通过局部相对的磁力悬挂的电磁驱动的无轴承的无密封的旋转叶轮。通过局部相对的磁力悬浮或通过由电磁力驱动的叶轮的磁力和流体力的组合来排除驱动机构中的轴承和密封件的需要。这避免了与其他泵送机构相关的热积聚和泄漏，这在泵送诸如血液的生理液体中是重要的。本发明的悬浮力相对于叶轮轴向和径向地施加。磁力通过由永磁体，螺线管或电磁体相对的二电磁体或螺线管的组合提供。本发明应用于许多医疗和非医疗应用，其中通过局部力量的叶轮悬浮的益处是显而易见的。

摘要： In an electric motor with a spherical air gap, wherein the rotor is supported by a bearing permitting rotation and rocking about the center of curvature of this gap. Both the stator and the rotor have elements with concentric surfaces of revolution in relation to the axis of rotation and facing each other which so overlap each other that they prevent a separation between rotor and stator.

摘要： A blood pump comprising: a pump housing, and a rotor mounted for rotation within the housing. The rotor has a rotational axis and an attached impeller. The blood pump has a blood flow path that passes about the rotor, with the rotor having a peripheral edge surrounding an end face. The end face has a profiled surface that augments blood flow radially outwardly from a central portion of the end face toward the peripheral edge as the rotor rotates when compared with a flat end face.
