INVENTOR: MAX PASBRIG INVENTION: CONTACT-BREAKING IGNITION PLUG AND METHOD OF GENERATING A SPARK THEREWITH A contact-breaking ignition plug comprises a magnet coil arranged in a housing and surrounding a magnet core. The magnet core comprises an enlarged end portion with lateral surfaces extending conically in relation thereto and also comprises a cavity in which an armature is movably arranged. The armature is mounted on a rod in asymetrical relation to a longitudinal center plane of the cavity and in transverse relation to the direction of compression pressure propagation. These features induce a concentration of the magnetic effect in the armature region and cause the contact-breaking motion to be augmented by the compression pressure. Respective contact electrodes are exchangably mounted at each of the free end of the armature and a nose of the housing. The contact electrodes are mounted such that an electrical ignition pulse traversing a short circuit path extending from the magnet coil of the electromagnet through the contact electrodes induces a magnetic field in the electromagnet, leading to interruption of the short circuit path and the formation of a spark. The interruption sequence can be accelerated by means of this contact-breaking ignition plug and can be more precisely controlled and no more material deformations arise during the contact-breaking motions. |
