ABSTRACT:
A compression spring capable of having a very high rate comprises co-axial annular plates alternating in an axial direction with diametrical strips adjacent ones of which are perpendicular to one another. The spring may comprise a stack of washers with diametrically opposed pads or radial ribs on their faces, said washers having non-circular bores enabling them to be located non-rotatably on a correspondingly non-circular central support. Alternatively, the spring may comprise a single tubular element with pairs of diametrically opposed tangential slots perpendicular to its axis which extend from its periphery into its bore.
