Ignition distributor

DETAILED DESCRIPTION It is therefore one object of the present invention to provide an improved ignition distributor which is high in noise suppressing effect and less in ignition energy loss.
Another object of the present invention is to provide an improved ignition distributor of the character described which is simple in structure and inexpensive to produce.
According to the present invention, these and other objects are accomplished by an ignition distributor for use in an internal combustion engine including a plurality of cylinders each fitted with an ignition plug, the ignition distributor comprising a plurality of fixed electrodes disposed in circumferential spaced relationship and electrically connected to the respective ignition plugs, a rotor electrode electrically connected to a power source and rotatable to successively face the fixed electrodes with a narrow gap with rotation of the engine thereby distributing power to the respective ignition plugs, and at least either of the rotor electrode and each of the fixed electrodes having its facing surface formed of conductive and insulating materials combined.
The facing surface of at least either of the rotor electrode and each of the fixed electrodes may be formed of a conductive material and formed therein with a plurality of slits filled with an insulating material.
Alternatively, a conductive layer impregnated with a liquid insulating material may be disposed on the facing surface of at least either of the rotor electrode and each of the fixed electrodes.
Other objects, means and advantages of the present invention will become apparent to one skilled in the air thereof from the following description.
