<p>A wave energy converter comprises a buoyant body (11) and an acceleration tube (14) dependent from and attached to the buoyant body (11) and having an upper end near the buoyant body and a lower end remote from the buoyant body. A section of the acceleration tube intermediate the upper and lower ends of the acceleration tube defining a working cylinder (16) and openings in the acceleration tube (14) above and below the working cylinder (16) allow substantially unobstructed water flow between the working cylinder and a body of water in which the acceleration tube is immersed. A working piston (17) is reciprocable in the working cylinder. A relief passage at the ends of the working cylinder (16) is controlled by the working piston (17) to allow substantially unrestricted flow of water past the working piston in response to the piston moving past a predetermined position at said end. An energy-absorbing device (19, 20, 24, 25) is operatively connected with the working piston (17). A restoring device (19C, 20C, 26, 27) is provided to apply to the working piston (17) an accelerating force directed towards the working cylinder (16) in response to the working piston moving past said predetermined position.</p> |
