Abstract:
A helical compression spring of a steel spring wire with several windings extending along its length wherein the helical spring can be pressed into a block, and wherein the helical spring has between its two end windings at least two types of windings with different external diameters, namely a first larger external diameter and a second smaller external diameter wherein these types of windings, when viewed in the longitudinal direction of the spring, are both arranged successively according to a specific pattern and wound so that the spring has diametrically opposite winding areas which, when viewed radially in relation to the longitudinal direction of the helical spring, are located approximately at the same level at least on one side whilst the diametrically opposite winding areas of the two types of winding are off-set at least approximately by the difference between the external diameters.
