  • Publication US 4,111,610 discloses a wave powered pumping system of a type adapted for installation in a body of water subject to surface wave motion.
  • a support structure is adapted to be mounted within the body of water, and a float is connected to a reciprocal structure which is movably connected to the support structure for permitting the float to rise and fall upon the water surface in response to wave motion.
