A drive assembly is provided suitable for aiding in the conversion of wave energy to useful energy. The drive assembly of the present invention is arranged to transfer wave energy to an energy converter, the drive assembly comprising, an actuating member having an actuating length. The drive assembly further comprises a movable energy transfer member arranged to be coupled to an energy converter and arranged to transfer energy from the actuating member to said energy converter. The drive assembly further comprises an energy storing member comprising a biasing member coupled to one or more of: the actuating member, the energy transfer member; the energy storing member being arranged to cause the actuating member or the energy transfer member to move position. The actuating member is arranged to move the energy transfer member from a first stroke position to a second stroke position; and the first stroke position and the second stroke position define distal end points of a working stroke; the working stroke arranged so as to drive said energy converter.

Assembly for transferring wave energy to an energy converter

A subsurface reaction body arranged for use in apparatus for converting wave motion in a body of water to useful energy is provided. The subsurface reaction body is arranged to be selectively filled with air to a maximum buoyancy configuration and to be filled with water to a minimum buoyancy configuration. The subsurface reaction body has an arrangement of chambers therein to inhibit free flow of water through the reaction body and to define at least one further preset buoyancy configuration between the respective maximum and minimum configuration.

Reaction body for wave energy apparatus

The generator comprises a float () which is movable in response to wave motion in a body of water, a submersible reaction member () of adjustable buoyancy, with at least two buoyancy configurations, connected to the float and arranged to resist movement of the float caused by the wave motion, an energy converter () for converting such reciprocal movement to useful energy; and biasing means such as a springfor directionally biasing the reciprocal movement. Displacement of the float relative to the reaction member is permitted and reciprocal movement generated in response to such displacement.
