<p>PURPOSE:To produce power through wind force efficiently by providing a cam interlocked with a rudder for sensing the direction of wind then automatically varying the open/close position of each vane of wind mill through cooperation with said cam. CONSTITUTION:Plural arm rods 3 are projected radially from the upper end section of a supporting tube 2 supported on a journal table. A frame 4 extending in parallel with the arm rod 3 is provided integrally with each arm rod 3 to support an arched vane 5 between the arm rod 3 and the frame 4 through a shaft 6 while a vane 7 comprised of plural arched boards is pivoted to the base vane 8 near to the outercircumference of the arm rod 3. While a cam 9 is fitted to the upper end of the spindle 2 inserted into the supporting tube 2 and a rudder 10 is secured to the upper face of said cam 9. A liquid pressure cylinder 12 is operated by the operation of the rudder 10 through the cam 9 to interlock other liquid pressure cylinders 12', 12'' through the liquid pressure thus to regulate the open/close angle of respective vane 5, 7, 8.</p> |
