    摘要： Disclosed is a blood pump for circulating blood by a rotor rotating in a space of a casing which is formed substantially in a flat shape and has a suction port and a discharge port, comprising: a conical projecting portion provided at the central portion of the rotor; and a blade body formed continuously to the vicinity of the outer periphery of the base portion of the projecting portion, in which upper side recessed passages and lower side passages alternately and radially formed; wherein base portions of the upper side recessed passages and the lower side passages are inter-connected to each other by communicating passages. With this blood pump, the passages for blood are formed at either of the upper and lower gaps between the rotor and the casing, so that blood is transferred to the outer peripheral portion, thus preventing the solidification of the blood due to the stagnation thereof.

    摘要： A rotary hydraulic machine having particular utility as a fuel pump for aircraft turbine engines that combines the desirable features of vane-type and centrifugal-type machines of similar character -ie, high pressure positive displacement at low speed combined with improved reliability, package size and weight. This is accomplished, in accordances with a presently preferred embodiment of the invention, by providing a combined vane- and centrifugal-type pump that is configured to function as a pressure-compensated single-lobe vane pump for engine starting, and as a centrifugal pump at normal operating speed.

    摘要： A pump according to the present disclosure includes a pump body, an impeller stored in a pump chamber formed inside the pump body, and a shaft that supports the impeller such that the impeller is rotatable. A pump channel extending from a suction port to a first discharge port is formed inside the pump body. The pump channel includes a suction path, an impeller channel which is formed inside the impeller and into which liquid in the suction path is introduced, a volute portion which is formed on a radially outer side of the impeller and into which liquid in the impeller channel is introduced, and a discharge path into which liquid in the volute portion is introduced. A liquid separation reduction structure that reduces separation of liquid flowing in the pump channel is provided in the pump channel.
