<p>PROBLEM TO BE SOLVED: To provide a displacement type pump with no valve, which is equipped with efficient pumping function without worthlessly loading on fluid particles of transferred flow body and without effecting on and damaging characteristic of the fluid particles, and which has a continuously and efficiently operated mechanism without effect of intermittent flow and pulsating flow. SOLUTION: The displacement type pump comprises: a chamber 12 of which inside volume is changed by external force with a plurality of openings 4 for intake and discharge; a spiral pipe 1 extending from at least one of the openings 4 in a direction of anticlockwise rotation; a spiral pipe 2 extending from at least one of the other openings 4 in a direction of clockwise rotation. Adopting the displacement type pump structure and fluid transfer method using the same attains the purpose.</p> |
