ABSTRACT:
A fluid-flow regulating device is comprised of (a) a plurality of driving mechanisms each of which has a chamber, a diaphragm disposed at an opening of the chamber, a light-heat conversion substance accommodated in the chamber, and an operating fluid stored in the chamber, (b) a fluid-flow passage along which the plurality of driving mechanisms are arranged in such a manner that each of the diaphragm is opposed to the fluid-flow passage, (c) a plurality of optical fibers corresponding to the plurality of the chambers, and (d) a controller having a plurality of optical sources corresponding to the plurality of optical fibers which are set to be turned on and turned off in order to move an amount of fluid through the fluid-flow passage in any one of the normal and the reverse directions.
