NOVELTY - The regulator has a sheet (1) or laminate that is wound in radioidal spiral form with increasing or decreasing curvature along the length of the spiral. The sheet absorbs energy at variable torque and supplies a practically constant torque in broad working areas. The sheet is made of composite materials with a polymer matrix and fiber reinforcement. The regulator is incorporated to energy production devices by coupling through a mechanical differential device which automatically regulates elastodynamic energy supply or accumulation.    USE - Elastodynamic energy accumulator regulator for use in a horizontal wind-powered generator, auxiliary energy unit of a hydrogen producing unit that is utilized in a fuel tank of a vehicle e.g. automotive vehicle, railway vehicle, marine vehicle (all claimed), and for use in wind energy production and renewable energies application, transport application, uninterruptible power supply system application and electric network regulation application.    ADVANTAGE - The sheet is wound in radioidal spiral form with increasing or decreasing curvature along the length of the spiral, and absorbs energy at variable torque and supplies a practically constant torque in broad working areas, thus achieving complete independence of energy input and output for elastodynamically regulating the output torque in reasonable minimum space.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a manufacturing procedure of a laminate or a set of sheets    (2) a wind-powered generator comprising a mechanical differential element    (3) a hydrogen producing unit comprising a mechanical energy producing device    (4) a vehicle provided with a fuel tank.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the sheet wound in the shape of a radioidal spiral in a simple configuration, wound upon a shaft that charges and supplies accumulated energy, and another shaft that charges and supplies the same energy, in reversible energy flow.
