Abstract
An ignition coil for an internal combustion engine includes a core assembly. The core assembly has a magnetically active core made of sheet-metal strips, a damping element and a sheath surrounding the core and the damping element. Different ways are described for improving the discharge of air trapped in the core assembly during casting of the ignition coil. For example, the damping element is designed with a V-shaped incision or a semipermeable diaphragm.
