Abstract
The present invention relates to a centripetally acting type of water turbine which uses low-head and low-speed water flow and which comprises a rotational force generating device having an inner and an outer centripetal canister rotatably supported by means of a stand and a securing shaft either vertically or to left and right in a straight line, and having a plurality of blades fixedly joined in a radiating fashion between the inner and outer centripetal canisters, and in which the combined shape of the inner and outer centripetal canisters and neighboring individual blades is constituted as a lower surface which inclines such that water or steam flows at an incline downwardly and, as it does so, the rotational radius progressively reduces.
