Distributor for an internal combustion engine

A distributor or an internal combusion engine comprising:

• a housing;
• a shaft rotatably mounted in said housing to rotate synchronously with the rotation of the internal combustion engine;
• a distributor rotor supported on said shaft and including a rotor electrode means for distributing generated high voltage;
• an outer distributor cap having first electrode means mounted therein and supplied with high voltage current and further electrode means mounted therein for supplying a distributed voltage from the rotor electrode means of the distributor rotor;
• an inner distributor cap of an electrically insulating material nested inside of said outer cap so as to form a space between said outer distributor cap and said inner distributor cap when said inner distributor cap and said outer distributor cap are mounted on said housing, said space being defined between opposed surfaces of said outer distributor cap and outer surfaces of said inner distributor cap respectively defining an inner and outer surface of the outer distributor cap and the inner distributor cap, and
• means for fixedly securing said outer distributor cap and said inner distributor cap to said housing.
