Patent ID: 10711760

Abstract:
A wave operated assembly (20) configured to be submerged in a body of water (12), the wave operated assembly (20) comprising a wave actuated member (24), a second portion and a piston assembly, pressure chamber (22) or spring coupled between the wave actuated member (24) and the second portion. The wave actuated member (24) and the fixed portion each define part of a first chamber (22) or volume comprising or configured to receive a fluid. A lower portion of the wave actuated member (24) at least partly defines a free surface (35) between the fluid within the first chamber (22) or volume and the body of water (12). The wave actuated member (24) is movable relative to the second portion. The piston assembly, pressure chamber (22) or spring is configured to apply a force on the wave actuated member (24) that works in opposition to a force on the wave actuated member (24) due to the fluid in the first chamber (22) or volume.
