ABSTRACT:
A wave power installation is presented, comprising a flow chamber, an air-driven turbine disposed in the chamber and coupled with an electro-generator, a float having a cavity accumulating air, communicated with the chamber, a vacuum-creating ejector disposed in water mounted under the float, which ejector is performed as a confuser-diffuser conduit, wherein at least a portion thereof is vertically positioned. The conduit has a minimal through cross-section. At least one reverse valve is mounted in the vicinity of the minimal cross-section. The conduit is communicated with the cavity via the reverse valve. The chamber and turbine can be located on a coast. In embodiments, the conduit is furnished with a cylindrical nozzle, thereby making it stepwise widening downwardly. During both the upward and downward motions of the float, airflow is produced through the chamber, providing for practically continuous generation of electric energy by the installation, and improving its efficiency.
