<P>PROBLEM TO BE SOLVED: To provide an gas-liquid mixed fluid force feed device on the blade surfaces of which air films are hardly formed and whose idling is suppressed. <P>SOLUTION: In the gas-liquid mixed fluid force feed device 1, a circular impeller 3 is provided inside a casing 2 rotatably with its center as the center of rotation, the impeller 3 has a suction port 6 formed in a central portion and a plurality of blades extending from the outer periphery of the suction port 6 to the radial side, the blades are curved in the peripheral direction and formed wider toward the radial side, and fluid flow paths are formed between the adjacent blades so that the width of each flow outlet on the outer peripheral edge side of the impeller 3 is smaller than the width of each inflow port near the suction port 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
