<P>PROBLEM TO BE SOLVED: To achieve a fluid transporter in which the delivery amount of fluid is precise. <P>SOLUTION: The fluid transporter 1 includes: a cum 20 as a rotor; a fluid delivery channel 15 formed on the side surface of a channel frame 14, and having a circular-arc-shaped groove 16 on a concentric circle around the rotation axis P1 of the cum 20, and a sheet-shaped elastic member 90; and a plurality of fingers 40-46 disposed between the cum 20 and the elastic member 90 to sequentially and repeatedly open and close the delivery channel 15 from the upstream side to the downstream side by deforming the elastic member 90 in accordance with the rotation of the cum 20. With this configuration, the accuracy of the cross-sectional area of the delivery channel 15 increases, which contributes to the reduction of the variations in the delivery amount of fluid caused by variations in the cross-sectional area of the delivery channel. Accordingly, the accuracy of the delivery amount of fluid improves. <P>COPYRIGHT: (C)2012,JPO&INPIT |
