ABSTRACT:
A compensation system for a spiral spring hysteresis selectively provides a reactive compressive force to the spring after retractive movement of the outermost spring end relative to a fixed axial center of the spring. Such reactive compressive force reflects what, otherwise, would be the difference between the reactive forces of extension and retraction of the spring and along an axis of greatest transmissibility of force to the spring. The spring constants of extension and retraction of the spring are resultingly compensated.
