PROBLEM TO BE SOLVED: To surely prevent bubbles from occurring from a fluid on a downstream side, when the fluid is transported by a transportation space formed with a stator and a rotor.SOLUTION: A fluid transport device includes: a cylindrical stator 2 formed at a predetermined pitch in a flow direction from a suction port to a discharge port, and having a female screw-shaped open hole 10; and a rotor 3 formed into a male screw shape, forming a transport space 11 between itself and the inner peripheral surface of the open hole by being inserted into the open hole 10 of the stator 2, and moving a fluid from the suction port side to the discharge port side in the transport space 11 while inscribed on the inner peripheral surface by rotation. The volume of the transport space 11 is reduced toward the flow direction.SELECTED DRAWING: Figure 2 |
