Abstract: A refrigeration apparatus includes a compressor, two or more cylinders coupled with the compressor, and an airproof container enclosing the cylinders and filled with air or other gas. Each cylinder is provided with a piston, an inlet valve coupled with the compressor, and an outlet valve coupled with a condenser. When inlet valves are open, outlet valves are closed, and pistons move from bottom to top of cylinders, refrigerant flows from compressor into cylinders through inlet valves; and when inlet valves are closed and outlet valves are open, refrigerant flows from cylinders into condenser through outlet valves. Then, air pressure in cylinders drops, and pressure in airproof container forces pistons to move to the bottom of cylinders. The pressure in airproof container is utilized by cylinders to produce electrical energy.

Abstract: A hydraulic motor for generating electricity with a water holding container with a conduit extending downwardly to a distribution valve assembly. A hydraulic shock valve assembly connected to a port in the conduit, adjacent to the distribution valve assembly, periodically imparts a shock to the water entering the distribution valve assembly with some water collected by a holding tank. The distribution valve assembly permits the water to go through to move a piston assembly. The moving valve member quickly moves from two end positions a spring loaded actuating mechanism that is unstable when the distal end of the valve rod reaches a predetermined position. The piston assembly also actuates as a wheel assembly that in turn drives an actuating valve assembly driving the hydraulic shock valve assembly and an electric generator that in turn powers a pump to bring water from the holding tank to the container.

Abstract: A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.
