Abstract
A device for storing and later releasing mechanical energy has an elongate body, preferably cylindrical, at least one elastic strip or band wound helicoidally about the body and fastened thereto at each end thereof. A rigid rod extends longitudinally through and supports the body. The strips are wound about the body by rotating one end of the body on the rod. The strips of elastic material are subjected only to tensile stress and can be greatly deformed to accumulate a large amount of energy. The dimensions of the device are relatively small and need not be varied to accumulate a large amount of energy. The device is useful for starting an internal combustion engine, a rechargeable element as a substitute for a motor or as an accumulator of braking energy of a motor vehicle.
