[Problem] A purpose of the present invention is to provide a fluid pressure-feeding device that can pump out and pressure-feed a pumping fluid from a bag in which said fluid is housed, leaving a sufficiently small amount remaining, even when said bag has a fluid-housing section and a non-fluid-housing section. [Solution] A fluid pressure-feeding device 10 has: a container 20 that houses a bag 100; a plate 50 that is mounted in the interior of the container 20, above the bag 100; and a pump 70 that suctions a fluid housed in the bag 100.

Axis eccentric screw pump with decreasing sectional area of stator with a constant diameter rotor
The present invention comprises: a stator 2 that is cylindrical and has a through hole 10, the through hole 10 in 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 rotor 3 that is formed in the shape of a male screw, is inserted into the through hole 10 of the stator 2 to form a transport space 11 with the inner circumferential surface of the through hole, and rotates to move a fluid from the inlet to the outlet through the transport space 11 while being inscribed on the inner circumferential surface. The volume of the transport space 11 is 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 space 11 formed between the stator 2 and the rotor 3.
