ABSTRACT:
A rotor for the high voltage distribution system of an internal combustion engine, the contact member of the rotor being movable relative to the rotor shaft for a desired advance-retard characteristic. The rotor itself does not move relative to the rotor shaft. The device is for use with electronic ignition systems and one function is to replace the mechanical advance provided in conventional breaker point type distributors by the centrifugal weights which rotate the entire cam and rotor assembly. A range of characteristics responsive to engine velocity and/or acceleration is provided for within the basic design.
