Abstract: A method and apparatus uses energy in an energy output system having a main power source, an energy transmission system and a mechanical output. A first portion of energy generated with the main power source is used to drive the mechanical output under operating conditions. The unused second portion of the energy is diverted to an energy storing means. The second portion of energy is then stored and regenerated on demand. The energy may be used directly to augment the energy requirements in the energy output system during peak periods. In a specific embodiment, a compressed air system is used for storing the energy not used in driving a mechanical output connected to the power source by an energy transmission assembly. The energy transmission in the energy output system is a hydraulic fluid transmission system. A hydraulic fluid diverting mechanism is used to maintain the flow of hydraulic fluid to the mechanical output and to the compressed air energy storage system.
Abstract: A power brake system has a brake booster operable by differential air pressure provided by a source of vacuum and a source of compressed air pressure. The differential air pressure control valve assembly of the invention maintains a substantially constant available differential of air pressure between the vacuum and compressed air pressures available to the brake booster for booster operation. In the charging mode it directs air pressure from an air pressure pump to an accumulator connected to the pressure inlet side of the booster, charging until the desired pressure differential is attained. In the storage mode, the air pressure from the pump is permitted to flow in its usual manner to another device or circuit utilizing the air pressure. This may be, for example, a part of the vehicle engine emission control system. In the pressure relief mode, the control valve vents excess accumulated pressure to exhaust.

Abstract: An oil-operated motor driven from an air-pressurized oil supply tank. The motor has sets of opposing cylinders having oil admission valves and containing drive pistons connected to a crankshaft. The cylinders are connected to the pressurized supply tank through the admission valves and respective ones of a pair of compressed air-controlled pilot valves. The pilot valves are controlled by relay valves alternately opened by a rotating cam driven by the crankshaft. The pilot valves control the delivery of pressurized oil to cylinders arranged to be alternately supplied with pressurized oil, with their pistons acting to drive the crankshaft in a common direction by alternate power pulsations. A common compressed air supply is employed to pressurize the oil reservoir and to operate the pilot valves. The exhaust oil from the motor is returned to the oil reservoir by a hydraulic pump driven by the main oil-operated motor.
Abstract: A system and apparatus for the storage of energy generated by natural elements. Energy from natural elements such as from the sun, wind, tide, waves, and the like, is converted into potential energy in the form of air under pressure which is stored in a large, subterranean cell. Machines of known types such as windmills are driven by natural elements to operate air compressors. Air compressors pump the air under pressure to the storage cell. Air entering the storage cell displaces water from the cell which returns to a water reservoir as an ocean or a lake. Water locks the air in the storage cell. The stored compressed air is available upon demand to perform a work function as driving an air turbine to operate an electric generator.
Abstract: A hydro or oleopneumatic device comprises a pressure transformer consisting of a single or multiple pneumatic cylinder having one or a number of stages in which the piston is rigidly coupled to an accumulator. The accumulator piston discharges the liquid to a function jack which utilizes the energy produced by the pneumatic pressure. The pneumatic cylinder is not provided with compressed-air exhaust ports and is freely connected to a compressed-air reservoir at the working pressure. The volume VR of the reservoir is large in comparison with the volume VC of the pneumatic cyclinder, the ratio VC/(VR + VC) being equal to the permissible variation in the working pressure of the air according to the intended use of the device.
