  • Shutter valve and device for generating energy from sea waves comprising such valves
    Patent number: 10145353
    Abstract: A shutter valve for alternatingly allowing and stopping a high pressure water flow, such as in a device for generating energy from sea waves, comprising a tube section (201) having a rectangular cross section, wherein a multitude of vanes (202) are rotatably mounted in the tube section (201), wherein the vanes have a relatively large rectangular longitudinal cross section in a first direction, a relatively flat rectangular longitudinal cross section in a second direction perpendicular to said first direction, and a generally flat cross section in a third direction perpendicular to said first and second directions, said third direction being the axis of the vane (202), wherein the circumferential wall around the axis of each vane forms a closed water impermeable surface, wherein the axes of said multitude of vanes all extend in a parallel manner, characterized in that the distances between the axes of adjacent vanes are approximately half the distance between the outer tips of the vanes, seen in the cross sect
