Ignition coil particularly for racing engines

摘要

The ignition coil includes a hollow metal body 18 fixed inside a casing 16 close to the edge 12a and electrically connected to one of the ends 24a of the secondary coil 24. A metal slider 36 is mounted so as to slide axially inside the hollow body 18 between an extension position and a retraction position, and one of its ends is designed to extend away from the hollow body 18 and to come into contact with a connector of the spark plug C. A spring 40 is interposed between the hollow body 18 and the slider 36 in order to push the slider 36 towards the extension position. The invention applies to racing engines and enhances the contact between the coil and the spark plug. <IMAGE>
