An automatic pumping apparatus utilizing a wave motion, having not less than one sink-and-float member provided so as to be moved vertically in accordance with a wave motion, and pistons positioned below the sink-and-float members, connected to the sink-and-float members which are combined with each other via a transmission means, and adapted to be moved slidingly in one-end-opened fixed cylinders in accordance with the vertical movement of the sink-and-float members, a horizontal cross-sectional area of each piston with respect to that of each sink-and-float member being set small in inverse proportion to pumping height, whereby the water can be pumped owing to the operations of the pistons to a storage tank through pumping pipes extending from the other ends of the cylinders to the positions higher than the ranges of vertical movements of the sink-and-float members. <IMAGE> |
