Abstract
The present invention comprises: a statorthat is cylindrical and has a through hole, the through holein the shape of a female screw and being formed at a certain pitch in the flow direction from an inlet to an outlet; and a rotorthat is formed in the shape of a male screw, is inserted into the through holeof the statorto form a transport spacewith the inner circumferential surface of the through hole, and rotates to move a fluid from the inlet to the outlet through the transport spacewhile being inscribed on the inner circumferential surface. The volume of the transport spaceis reduced toward the flow direction. This prevents, reliably, the occurrence of bubbles from a fluid at a downstream-side when the fluid is transported through the transport spaceformed between the statorand the rotor
