摘要： An ignition distributor for an internal combustion engine has a cylindrical distributor rotor of synthetic resin, rotated synchronously with the revolution of the engine, and a rotor electrode radially and outwardly extending from the central portion on the upper surface of the rotor. A plurality of circumferential electrodes are disposed in the rotating locus of the rotor and are separated from the rotor electrode by a discharge gap. The rotor electrode has the shape of letter T a vertical portion of which is fixed to the distributor rotor and a horizontal portion of which opposes to the circumferential electrode, being in the shape of a circular segment. The surface of the rotor electrode horizontal portion opposing to the respective circumferential electrodes is formed to have a rugged or wavy profile comprising a plurality of peaks and the rugged surface is coated with a dielectric material such as silicon varnish to provide a low discharge voltage and reduced radio frequency interference in prolonged use.

摘要： A distributor for suppressing radio frequency interference (RFI) in the ignition system of an internal combustion engine including a rotor electrode having adhered thereto on at least one of its surfaces a wire net combined with a dielectric material and a contact electrode making contact with the rotor electrode for supplying a high voltage from an ignition coil to the rotor electrode. Various types of dielectric materials and wire nets are used. Also, a plurality of wire net, including the dielectric material, can be utilized to prevent the exfoliation of the dielectric material from the rotor electrode.
