Abstract
A wave motion-actuated pumping apparatus includes a pair of inner and outer telescoping sleeves, a float, an anchoring arrangement, and a pair of one-way flow valves. The inner and outer sleeve are telescopically fitted together for reciprocal sliding movement relative to one another and define a water flow chamber therebetween being variable in volume in response to reciprocal movement of the tubular members relative to one another. The inner and outer tubular members also respectively define an inlet to and an outlet from the chamber. The float is attached about the outer sleeve so as to provide it with sufficient buoyancy to floatably follow up and down motion of waves with the float when the float and outer sleeve are disposed in a body of water. The inner sleeve is attached to the anchoring arrangement to restrain the inner sleeve from following up and down motion of waves with the outer sleeve, thereby causing the outer sleeve to reciprocally move relative to the inner sleeve. The upper and lower one-way flow valves are mounted respectively to the inner and outer sleeves across the respective inlet and outlet of the chamber in an arrangement which produces opening and closing of the valves in response to, and thereby in coordination with, reciprocal movement to the outer sleeve relative to the inner sleeve so as to cause pumping of water from the outlet of the chamber.
