<P>PROBLEM TO BE SOLVED: To provide a uniaxial eccentric screw pump pressure feeding a liquid having a poor flowability, which makes a pushing force of a pushing screw efficiently act on even to a neighborhood of suction port of a stator. <P>SOLUTION: The uniaxial eccentric pump 1 includes: a stator 11 having a screw pump 10 rotatably pivoted; and a rotar 12 directly connected to a drive shaft 31, and the rotary axial line L2 of the rotar 12 is arranged below the rotary axial L1 of the stator 11 eccentrically by a predetermined distance E. The pushing screw 20 is rotatably pivoted in a casing 28, and the pushing screw 23 driven separately from the drive shaft 31 is arranged above the rotary axial line L1 of the stator 11, and the end 23s is arranged near the drive shaft 31, facing the suction port 4 of the stator 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
