Wave energy pump has float on air/water surface which is connected by a piston rod to a spring return piston in a submerged cylinder with non return valves mounted on the bottom of the water

摘要

A float (4) at an air/water surface (3) is connected to a piston which is spring loaded (7) and moves in a cylinder (6) guided by supports (5a,5b,5c). The cylinder and piston have non return valves (8a,8b,8c) which enable a liquid to be pumped by the energy derived from waves at the air/water surface. The whole equipment stands on the bottom of the water using a base (19)
