ABSTRACT:
A wave driven pump includes a buoyant wave follower having an elongated hollow body member depending therefrom with a piston in the body member. The remote end of the body member or cylinder is moored to the sea floor, and the piston is also moored so as to maintain its vertical position generally constant. Means are provided to permit the portion of the cylinder containing the piston to move up and down with respect to the piston in response to wave movements so that a pumping action results to pump water from a pumping chamber in the cylinder upstream from the piston.
