Fluid transporter

摘要

A fluid transporter includes: a rotor; a fluid delivery channel which has a groove having a circular-arc shape around a rotation axis of the rotor and disposed on a surface of a channel frame opposed to the rotor, and a sheet-shaped elastic member sealing an opening of the groove; and a plurality of pressing members disposed between the rotor and the elastic member to sequentially and repeatedly open and close the delivery channel from the upstream side to the downstream side by deforming the elastic member in accordance with the rotation of the rotor.

1. A fluid transporter comprising:
a rotor having an outer peripheral circumferential surface; a fluid delivery channel which has a groove, the groove having a circular-arc shape on a concentric circle around a rotation axis of the rotor, the concentric circle having a diameter larger than a periphery of the rotor; a sheet-shaped member attaching to and fluidly sealing the groove; and a plurality of pressing members disposed between the outer peripheral circumferential surface of the rotor and the sheet-shaped member and selectively engageable by the outer peripheral circumferential surface of the rotor; wherein the plurality of pressing members contact and deform the sheet-shaped member in accordance with the rotation of the rotor; wherein an elastic force of the sheet-shaped member shifting the plurality of pressing members towards a rotation axis of the rotor upon disengagement of the plurality of pressing members from the rotor.
