<p>PURPOSE: To smooth rotation of a rotor sqeezing a hose by moving rolling positions by turning of rolling parts. CONSTITUTION: A pump device is provided with a rotor 14 to rotate while having rollers 18 projecting outside, a hose 24 making almost one round along the outside of a locus in which the rollers 18 turn when the rotor 14 rotates, inlet outlet pipes 26 respectively arranged in both end parts of the hose 24, a driving gear 32 to rotate the rotor 14 by receiving driving force, a rotor gear, a rotary arm and a pressing wall 12a which is arranged so as to make almost one round along the outside of the hose 24 arranged in an almost annular shape and collapses by sandwiching the hose 24 together with the rollers 18. The rotor 14 rotates by receiving driving force, and the rollers 18 of the rotor 14 turn, and rolling positions of the hose 24 are moved by these rollers 18 and the pressing wall 12a, and since a shape of the hose 24 is restored in a part to which the rollers 18 are not pressed, inside fluid of the hose 24 is flowed, and the fluid is sucked in from one inlet outlet pipe 26, and the fluid is delivered from the other inlet outlet pipe 26.</p> |
