<p>A submersible power plant (10) comprises a submersible enclosure (12) having at least one intake valve (16) for admitting water at high pressure from the surrounding sea into and air space in the enclosure. An air shaft from the air space (96) is in communication with the atmosphere for maintaining the air space at approximately one atmosphere. A pump for evacuating water collected in the enclosure includes a buoy (62) responsive to ocean swells. A piston haft (58) connected to the buoy reciprocates in the center bore (60) of a vertical column (52) extending upward from the bottom of the enclosure. As the piston shaft rises inflow valves (72) admit water in the enclosure into a valve housing (70) in communication with the center bore. As the piston shaft falls water is discharged from the valve housing into the sea through a discharge valve (80) in the bottom of the enclosure.</p> |
