<P>PROBLEM TO BE SOLVED: To provide a uniaxial eccentric screw pump follow-up rotating a stator in the number of rotations half of a rotor with a rotation force, which follow-up rotates the stator by keeping a correct phase relationship, even when a rising accelerating time at the start is shortened. <P>SOLUTION: The stator 41 of the uniaxial eccentric screw pump 1 has a structure to have an elastomer part 41g having its female screw shaped inner surface, formed in a constant thickness. <P>COPYRIGHT: (C)2013,JPO&INPIT |
