ABSTRACT:
An ignition distributor for internal combustion engines that improves ventilation efficiency, particularly when a rotor electrode does not come close to counterelectrodes, and that protects against the effect of an unfavorable thing to the outside of the distributor, which triggered by the discharge action. A closure member is provided that is mounted on to the distributor shaft and is in position adjacent to the inboard openings of ventilating holes formed in the housing which communicate the inside of the housing with its outside for ventilation. The member controls the communication therebetween for substantially restricting the communication when the discharge occurs in the housing and opening it when the discharge does not occur. The opening and closing of the communication is alternately repeated in response to the exact ignition discharge timing.
