The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

A system and method for producing compressed air from ocean waves. The system includes an enclosing frame having a base anchored to an ocean floor with two or more columns extending upward from the base to above the ocean surface and a platform at an upper end of the columns. A float is located in the frame between the columns so that the float is confined to go up and down. The float is placed on the ocean surface within the frame and goes up and down with the ocean waves. One or more pumps are located on the platform with the hammer head that can be raised and lowered to produce compressed air with the pumps. The hammer head is connected to the float with two or more elongated shafts so that the hammer head is raised and lowered by the ocean waves and produces compressed air.

A wave energy converter includes a buoyant body and an acceleration tube with a working cylinder and working piston movable therein, a mooring system, and at least one energy collecting device including a differential cylinder having an internal pump piston connected to the working piston via a piston rod. The differential cylinder includes a pumping chamber and an annular pumping chamber. When decreasing volume of the annular gap-shaped pumping chamber, the pump piston expels hydraulic fluid from the pumping chamber toward the pressure accumulator and draws hydraulic fluid from the fluid tank into the substantially cylindrical pumping chamber. During a working stroke causing a decrease in volume of the substantially cylindrical pumping chamber, the pump piston causes hydraulic fluid to bypass the pump piston through a fluid connection from the substantially cylindrical pumping chamber into the annular gap-shaped pumping chamber and further in a direction toward the pressure accumulator.
