An apparatus is described for the conversion of complex surface motion of the sea or other fluid body into useful energy, comprising a pair of floating bodies, each of which constitutes a wave motion pump; the pair of floating bodies being linked by a lever whose motion serves to initiate and multiply the pumping energy of each. Each floating body contains two piston operated water cylinders with water intake check valves at their bases and a third cylinder serving as a pressure chamber. Each floating body contains its own fulcrum such that it rocks about one end of the lever. The downward pivotal motion of the lever on the piston shaft of the piston in one of said water cylinders forces water out of the cylinder. Simultaneously, the upward motion of the lever on the other side of the fulcrum pulse the piston shaft of the other piston upward, causing water to be taken into the other cylinder through the intake check valve at its base. As the action of the lever reverses, the action of the pistons reverses, causing a constant flow of water under pressure into the pressure chamber from which it exhausts. The same sequence of events occurs in the second floating body, thus causing the effect of a dual pump. Air pressure is utilized to reinforce this process. Since the apparatus has four cylinders alternately and sequentially forcing water through defined channels, the effect of an efficient pump is created, which might be utilized for any normal purpose.
