Abstract

PURPOSE: To easily manufacture impellers for fluid and control rotation speed by fixing several elastic boards to a rotary shaft, pulling the ends thereof by a metal wire so as to give a twist, and using the boards as impellers of a rotating fluid machinery. CONSTITUTION: An elastic board 1 is fixed to a rotary shaft 5, metal wire supporting points of respective tips are tensed by metal wires 2 so as to give twists to the boards 1. Each board is rotated in the direction of an arrow B. When the flow of fluid in an arrow A is increased, the rotation speed of the rotary shaft 5 is also made fast. When the rotation speed of the rotary shaft 5 is made fast, each weight 3 which is installed on the intermediate position of the metal wire 2 is moved in the direction of an arrow C by centrifugal force. The twist of the board 1 of the elastic body is enlarged by this force so as to reduce the rotation speed. Such impellers are installed on a wind machinery, and thereby, manufacture thereof is carried out simply.

And the metal wire or metal rod supporting point 4 at the tip portion is pulled by (metal wire or metal rod 2 in FIG. 1 and coil spring 6 in FIG. 2) to twist the elastic plate 1. This twisted elastic plate 1 rotates the rotary shaft 5 in the direction of the arrow B. When the fluid flow in the direction of the arrow A increases, the rotation speed of the rotating shaft 5 increases. As the rotation speed of the rotating shaft 5 increases, the weight 3 attached to the middle of the metal wire or the metal rod 2 moves in the direction of arrow C by centrifugal force. This force changes the twist of the elastic plate 1 (increases in FIG. 1 and decreases in FIG. 2), which reduces the rotational speed.
