Abstract

A wave power hydraulic system comprising at least one piston unit, wherein each piston unit comprises a respective piston (4a, 4b) moveable within a respective cylinder (8a, 8b), each piston unit comprises a first cylinder chamber (40a, 40b) on one side of the piston and a second cylinder chamber (42a, 42b) on the other side of the piston, the hydraulic system is connectable to a mechanical member (5) to drive movement of the or each piston in response to wave motion, thereby to drive fluid from each chamber along a respective fluid flow path, each fluid flow path being connectable via a check valve arrangement (14a, 14b, 16a, 16b, 18a, 18b, 20a, 20b) to a power takeoff system, and the system further comprises control means for varying the configuration of the hydraulic system to vary the flow path from at least one of the chambers thereby varying the volume of fluid provided via the check valve arrangement to the power takeoff system in response to a given piston movement.
