Abstract
A multiturn, crest to crest, waved compression spring is formed with flat circular shim end portions which form load support surfaces at opposite ends of the spring which are generally perpendicular to the spring longitudinal axis. The compression spring includes three distinct wave regions in which the first distinct wave region has a constant, preselected amplitude, the second distinct wave region has a gradually and incrementally diminishing amplitude and the third distinct wave region has a constant zero amplitude.
