IGNITION DISTRIBUTOR ROTOR WITH AN INTEGRAL HOLD DOWN SPRING

摘要

A spring biasing mechanism is integrally molded to the rotor element of an arc-gap conduction type distributor wherein no mechanical contact is maintained between a common high voltage electrode and the rotor element and between the rotor electrode and the spark plug electrode. The spring biasing mechanism provides a downward biasing force to the rotor element to keep it rotating at a constant level with respect to the spark plug terminals and provides an upward biasing force to the cap to keep it properly spaced with respect to the base. In this way, the rotor electrode is maintained in proper height alignment with the spark plug terminals and an open vent channel is maintained to purge ozone from the commutation cavity.
