A torsional vibration damper comprising at least two components which can be twisted against the resistance of at least one energy storage element, spring coils extending along its longitudinal axis. The components have forced-application areas for compressing the energy storage element. The invention also relates to a helical compression spring made of steel spring wire which has a plurality of coils along its length and can be compressed until it becomes blocked. Between its two terminal coils, the helical spring has at least two types of coils having different external diameters, namely a first larger external diameter and a second, smaller external diameter. Viewed along the length of the spring, these types of coils are arranged in sequence according to a certain patent and wound in such patent that the spring has diametrically opposed coil areas which in relation to the longitudinal direction of the helical spring, viewed in the radio direction, on one side are at least approximately at the same height, whereas the diametrically opposed coil areas of the two coil types are offset at least approximately by a value equal to the difference between their external diameters.
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.
