Abstract
Magnetic pulse type ignition distributor in which the magnetic pulses are oduced by a pole-carrying timer core rotating in the magnetic gap between two stationary poles of a magnetic circuit. The timer core is enclosed in a sealed casing made principally of a non-magnetic metal. The stationary poles enter this casing through openings partially defined by a non-conductive material to avoid heating due to eddy currents. Means are provided for minimizing the friction produced by rotation of the timer core, and for facilitating the mounting of the casing and the remainder of the distributor in a position in which the timing is sufficiently well adjusted to permit operation of the motor.
