Abstract: Apparatus for extracting energy from an oscillating working fluid, the apparatus comprising a flow passage 40 for the oscillating working fluid, an energy conversion unit 44 and a flow control device 38, each of the energy conversion unit 44 and the flow control device 38 being, at least in part, in fluid communication with the flow passage 40, wherein in use the flow control device 38 is selectively operable between a first configuration in which the flow control device 38 is open to allow a flow of the oscillating working fluid to exit the flow passage therethrough, and a second configuration in which the flow control device 38 is arranged to restrict a flow of the working fluid therethrough, such that the oscillating working fluid enters the flow passage via the energy conversion unit 44.

Abstract: An apparatus and method is disclosed for extracting energy from an oscillating working fluid, such as ocean waves. The apparatus (10) comprises an internal flow passage (40) for the working fluid, a turbine (44) and a flow control device (38), each of the turbine (44) and the flow control device (38) being in direct fluid communication with the flow passage (40), wherein in use the flow control device (38) is selectively moveable between a first configuration in which the flow control device (38) is open to allow a flow of the working fluid, such as air, to exit the flow passage (40) therethrough, and a second configuration in which the flow control device (38) restricts a flow of the working fluid therethrough. In such an instance, the working fluid then must enter the flow passage (40) via the turbine (44), which can be harnessed to generate electricity.
