<p>PURPOSE:To provide a low vibrational pump having excellent volumetric efficiency by changing the inclining direction of a moving piece in a condition that the circular moving piece having an inclination to the axis is brought into line contact with a stator, and exhibiting pump action while moving a line contact part in order in the peripheral direction. CONSTITUTION:A flat moving piece 1 is arranged in a stator 2 surrounding it, and a pump chamber 3 is defined. 'The moving piece 1 is supported with a shaft while having an inclination to the axis, and a line contact part 5 is moved in the peripheral direction 11 along the moving piece 1 by changing the inclining direction of the moving piece 1 in a condition that a part 5 of the moving piece 1 is brought into line contact with the stator 2. A notch 7 is arranged in a part of the moving piece 1, and a partition 8 is arranged in a part of the stator 2 so as to be meshed with this notch 7, and an inflow port 9 and an outflow port 10 are arranged in the stator while sandwiching the partition 8 between them. Fluid suction and pressure exhaust are carried out simultaneously before and after the line contact part 5 along the peripheral direction of the line contact part 5, so that pump action can be exhibited.</p> |
