Wave pump apparatus

Claim 1

A wave pump apparatus comprising a frame of the submersible type, floats mounted on the frame and adapted to float the frame, the floats including at least a pair thereof which are spaced apart one from the other a distance approximating the average wave length of a particular wave pattern, the floats being adapted to be moved relative to each other depending on the wave length of a wave pattern on the body of water, a plurality of wave pumps provided on the frame, each wave pump including a cylinder, a piston movable in the cylinder, a float on the exterior of the cylinder directly connected to the piston, chamber means communicating with a bottom of the cylinder including a one-way valve provided at an inlet into the chamber allowing water to be drawn into the chamber as the piston is moved upwardly in the cylinder, a second one-way valve provided at an outlet of the chamber to allow water to flow through the outlet when the piston is moved downwardly in the cylinder, the plurality of water pumps being spced approximately one half wave length from the floats on the frame such that the floating portion of the wave pump is at the crest of a wave when the floats are in the respective valleys of waves and vice versa.
