Known prior art wave action generating systems commonly translate the vertical wave action forces to horizontal rotation which can be utilized for driving generating equipment. Also known are apparatuses wherein pumps are employed which function to pump water consequent to wave action forces, with such water directly or indirectly driving generating equipment. In accordance with the present invention, each pump assembly (2) is operatively connected to a float member (50) which is positioned in a float carriage (40) which eliminates twisting of the float member (50) and the piston rod (64) of the pump assembly (12). In a preferred form of the invention a shallow reservoir (20, 106) is provided and confined by a cofferdam (100) or silo (10) so as to provide a hydrostatic head between the reservoir (20, 106) and the open body of water exterior to the cofferdam (100) or silo (10). The hydrostatic head drives turbine generators (18), and spent water is discharged form the generators into the reservoir (20, 106). The pump assembies (12) and float carriages (40) are mounted on the exterior of the cofferdam (100) or silo (10) and function to withdraw water from the reservoir (20, 106) responsive to upwardly directed wave forces thereby maintaining the hydrostatic head. |
