Patent ID: 7952456

Claim:
An ignition coil for an internal combustion engine comprising: a primary winding supported by a substantially cylindrical primary coil base; a low voltage connection area for the connection of the primary winding to a low voltage; a secondary winding that is inductively coupled with the primary winding and that is positioned on a substantially cylindrical secondary coil base to provide a high voltage for a spark plug of the internal combustion engine; wherein the primary coil base and the secondary coil base are concentrically positioned relative to one another, and a high voltage connection area, in which the secondary winding contacts the spark plug; wherein an electrically conductive, substantially cylinder formed layer with mechanical dampening properties is located within an annular space defined by the outermost winding of the two windings; and wherein the electrically conductive layer is formed as a sandwich structure comprising at least two partial layers with a intermediate layer with mechanical dampening characteristics lying therebetween.
