Patent ID: 7946113

Claim:
An apparatus for generating power using energy from fluid wave action comprising: a plurality of floatation buoys each attached by a tether line to a hydraulic pump assembly, each buoy configured to float near the surface of a body of fluid, and to be so designed as to move significantly when acted upon by motion in said body of fluid; each hydraulic pump assembly being anchored to the solid floor beneath said body of fluid and having: at least one guide roller for the tether line connecting the buoy to the hydraulic pump assembly; a sealed, generally cylindrical outer housing; a hydraulic pump assembly containing an inner piston and ramrod assembly, having the piston slidably mounted within, and a counterweight connected to said piston, the piston thus configured to respond to the described motion of the associated buoy by moving in an upward direction within the cylindrical housing when pulled by the tether line and moving in a downward direction when acted upon by the counterweight; the inner piston and ramrod assembly, combined with the counterweight forming a hydraulic pump boom, which moves a hydraulic fluid in a closed hydraulic fluid loop along an output hydraulic line from the cylindrical housing to a hydraulic rotator pump, and receiving hydraulic fluid from a hydraulic fluid reservoir along an input hydraulic line; a bellows that keeps the body of fluid and any near-by debris outside of the cylindrical housing and permits passage of the tether line into the cylindrical housing while allowing movement of the buoy in response to motion in the body of fluid; and a slide track for guiding movement of the counterweight; a drive axle and generator assembly comprising: the hydraulic fluid reservoir for supplying hydraulic fluid to the closed hydraulic loop; the hydraulic rotator pump which receives the hydraulic fluid under pressure from the hydraulic pump assemblies and uses the hydraulic fluid to rotate a plurality of cable spools having cables attached thereto; a plurality of weights, one associated with each cable spool, each weight connected to the end of its associated cable and housed in an associated silo, the weights designed to rise as the cable spools rotate under the influence of the rotator pump and designed to disengage from the influence of the rotator pump and free fall upon reaching a predetermined position, the falling of said weights thus turning an input shaft of a continuously variable transmission; and upon reaching the lowest point in its free fall, said weights re-engaging with the influence of the rotator pump; a flywheel connected to an output shaft on the continuously variable transmission for temporarily storing kinetic rotational energy derived from the falling weights; a constant velocity transmission attached to the flywheel for providing a constant rotational motion from which any acceptable process or provision may be supplied with power.
