<P>PROBLEM TO BE SOLVED: To provide a fluid force power generation device in which shaft power loss caused by the fact that one propeller works as a brake on the other propeller can be prevented and thereby the power generation efficiency can be improved. <P>SOLUTION: A first propeller 5 and a second propeller 6 having different rotational directions from each other are disposed on both ends of a body 4 and are coupled to a first rotational shaft 7 and a second rotational shaft 8, respectively. The power of the first rotational shaft 7 is transmitted to a first element 41 (differential 40) by a first one-way clutch 20, and the power of the second rotational shaft 8 is transmitted to a second element 42 (differential 40) by a second one-way clutch 30. When the rotation speed of the first propeller 5 decreases and the rotation speed of the first rotational shaft 7 becomes relatively smaller than that of the first element 41, the power transmission from the first element 41 to the first rotational shaft 7 is blocked by the first one-way clutch 20. The first propeller 5 is prevented from working as a brake on the second propeller 6 rotating at higher rotation speed, the shaft power loss can be prevented, and thereby the power generation efficiency can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
