IGNITION DISTRIBUTOR

摘要

IGNITION DISTRIBUTOR An ignition distributor for an internal combustion engine in which the rotor is locked in a predetermined position by a locking pin fixed to the base of the distributor and having a portion thereof positioned in a slot formed in a plate that rotates with the distributor shaft and rotor. The rotor is locked in a position in which the electrode or segment thereof faces or is aligned with one of the output terminals of the distributor cap and when the distributor shaft is driven by the engine the locking pin breaks or fractures to permit free rotation of the rotor. With the arrangement that has been described, the distributor can be assembled to an engine and after assembly provides proper ignition timing without rotative adjustment of the base and cap relative to the rotor. One end of the locking pin is press-fitted to a bore formed in the base of the distributor so that the pin is permanently fixed to the base.
