Hydrostatic wave energy conversion system

摘要

A system for conversion of hydrostatic pressure variations of sea waves into useful energy is disclosed. The system is comprised of a sealed casing (12) with a membrane-like cover (16). The cover operates piston (52) under the pressure of the waves. The piston compresses air into vessel (22), from which it is discharged (86) to drive turbine (24) and produce electric energy (26). The piston (52) is recoiled back upwards by second piston (56), reciprocable within cylinder 58. The effective volume of the cylinder 58 is variable for counter-pressure adjustment purposes.
