Abstract
A distributor for use in an electronic ignition system, in which a rotating electrode is formed of a metallic material, and a dielectric material is provided connected thereto, contacting through a very small area at a portion apart from the sparking surface of the metallic member. The dielectric constant of the dielectric member is larger than that of a rotating body holding the rotating electrode.

Electrode arrangement for a rotor in a distributor of an internal combustion engine of the type having a rotating electrode and a stationary electrode for supplying a high voltage to a discharge region of a sparking surface of said rotating electrode, at an outer periphery of said rotating electrode, when said discharge region is rotationally adjacent said stationary electrode, said electrode arrangement comprising:
- a rotating electrode made of an electrically conductive material and mounted on said rotor;
- and
- at least one dielectric element mounted on said rotor;
- wherein;
- said at least one dielectric element is in electrical contact with said rotating electrode, and is mounted on said rotor adjacent said outer periphery of said rotating electrode, at a location which is angularly removed from said discharge region relative to a direction of rotation of said rotor, whereby said at least one dielectric element is not rotationally adjacent said stationary electrode when said discharge region is rotationally adjacent said stationary electrode and said stationary electrode delivers said high voltage to said discharge region.
