  • Patent number: 4926087
    Abstract: An electrical igniter has an outer metal shell within which extends a semiconductive tubular pellet that provides a cylindrical cavity which opens through an orifice formed by an inturned lip of the shell which forms a first electrode of the igniter. The diameter of the cavity and the diameter of the orifice are in the ratio of about 5 to 6. A second electrode extends axially within the shell into the rear end of the pellet with which it makes electrical contact. Discharge between the first and second electrodes causes a plasma of discharge products produced in the cavity to be ejected through the orifice.
