PURPOSE:To obtain a very large wind receiving area as compared with the same area of a fan as well as the electric generator prominent in both of the efficiency and the stability of the device by a method wherein wind-powered generation is effected by utilizing a differential pressure produced by a venturi effect generated in a path through which airstream is introduced. CONSTITUTION:Wind, introduced from the front face of a wind introducing path 7, is introduced into a discharging side path 8' and an introducing side path 8 respectively under being increased in the speed thereof in the wind introducing path 7 choked in accordance with the curvatures of wind introducing sections 3, 5. In the discharging side path 8', the wind is increased in the speed thereof by a choking section 2' and the pressure thereof is reduced. On the other hand, in the introducing side path 8, the wind enters into an air reserving chamber 11 from the choking section 2 through the introducing section 21 and the pressure thereof is increased. Here, an air discharging valve 43 is opened, the air in an exhaust chamber 13 is induced through discharging ports 23, 25 and the pressure of the air is made negative, then, the fan 17 is rotated by airstream generated by the pressure difference between both chambers 11, 13 and a generator 19 is driven through a reduction gear 45. |
