Abstract

PURPOSE: To produce large energy to fluid even with use of a fluid pump in small diameter, by providing an impeller, causing a component circumferentially stable, in the outlet side of the fluidic pump and forming a free flow line in its outside.
CONSTITUTION: A fluidic pump 3 rotated by rotary motion of a prime moving shaft 1 through a gear train is constituted in such a manner that an impeller is provided with a blade angle of the same direction as the direction of rotation of the impeller in its outlet side, and an impeller 4 separately rotated is provided in its outside. To the outside of said impeller 4, there is provided a free flow line 5 of at least 1.25 in radius to an outlet of the free flow line when assumed 1 for a radius of the pump3. Said impeller 4 is provided for obtaining a component circumferentially stable in the free flow line 5. In this way, large energy given to a fluid can be obtained even by the small radius pump 3, thus its performance can be improved when applied to a fluidic speed changer combined with a turbine 6 and guide vane 7.
