1. A fluid transporting device comprising:
- an elastic tube;
a tube frame having a tube guide wall for mounting said tube in an arcuate shape;
a rotary disc arranged on an inner side of said tube, said rotary disc operable to rotate about an axis of rotation;
a rotary push plate mounted to said rotary disc by a plurality of support pins, said rotary push plate secured to said plurality of support pins by a plurality of C-rings that correspond to each of said support pins, and said rotary push plate operable to rotate about said axis of rotation with said rotary disc;
a plurality of push pins oriented perpendicular to said axis of rotation of said rotary push plate, said push pins being disposed between said tube and said rotary push plate; and
said rotary push plate having a plurality of lobes integral therewith arranged at equal intervals with respect to the axis of rotation of said rotary push plate;
wherein an arcuate center of said tube guide wall, the axis of rotation of said rotary push plate, and a radial center of said push pins are aligned with each other; and
any one of the plurality of lobes simultaneously pushes a plurality of the push pins to feed the fluid from the fluid inlet side to the outlet side.

Abstract
A fluid transporting device is of a writhing type for transporting a fluid continuously. The fluid transporting device comprises a plurality of push pins arranged along a tube and radially on a concentric arc for squeezing a portion of the tube through which the fluid is fed and having elasticity substantially at right angles, and rollers 50 to 53 for pushing those push pins sequentially from the inlet side to the outlet side of the fluid. With this structure, it is possible to provide a thin, small fluid transporting device for continuing a stable flow rate, and a fluid transporter having the fluid transporting device.
