<P>PROBLEM TO BE SOLVED: To provide a uniaxial eccentric screw pump in which a stator can be readily separated into an outer cylinder and a lining member, and in which problems such as position deviation and deformation of the lining member and uneven abrasion due to the deviation and deformation and unstable discharge amount can be eliminated. <P>SOLUTION: The stator 20 includes: a one-piece cylindrical liner part 22 having a female thread on the inner circumferential surface thereof; and an outer cylinder part 24. Flange parts 26, 26 are provided protruding radially outward at both end portions of the liner part 22, and an outer cylinder fitting part 28 is provided between the flange parts. The outer cylinder part 24 is fitted to the outer cylinder fitting part 28 in a non-adhesive state, and both end portions of the outer cylinder part are abutted on the flange parts 26, 26. <P>COPYRIGHT: (C)2012,JPO&INPIT |
