Definitions

  • This invention relates to an ignition system for jet engines and the like, and more particularly to an ignition circuit which is suitable for use with low voltage spark plugs which operate on condenser charges and discharges.
  • the present invention overcomes all of the foregoing disadvantages by providing a novel circuit which utilizes low tension spark plugs.
  • the spark plug used with this circuit is one such as disclosed in applicants Patent No. 2,125,035, issued July 26, 1938, for Electric Ignition System and Sparking Plug for Internal Combustion Engines.
  • the essential feature of such spark plugs is that they employ relatively low voltages and provide a spark which, in effect, creeps across the surface of the plug. This creeping discharge is attained by providing a semiconductor between the electrodes of the plug.
  • the advantages derived from this arrangement are numerous, one of the principal novel results being the obviation of cleaning the plugs.
  • the spark plug described provides a spark which cannot be blown out since it does not rely upon the air as a conducting medium and therefore is not affected by variations in the atmospheric conditions.
  • each spark plug is fired three times for each revolution of the rotor.
  • the remaining condenser will serve to fire all of the spark plugs once during each revolution of the rotor. In this manner greater assurance of firing the spark plugs under any circumstances is provided.
  • the primary object of this invention is to provide an ignition system for jet engines and the like in which a spark plug is provided for each combustion chamber and in which each spark plug is fired sequentially by three independent condensers so that relighting blown out chambers may be more easily accomplished.
  • a further object of this invention is to provide an ignition system for jet engines and the like which utilizes low voltage spark plugs having a creeping discharge and in which condensers are used to fire the spark plugs.
  • Another object of this invention is to provide an ignition system in which a rotor is used to sequentially connect each of three condensers with successive spark plugs.
  • individual condensers 16 are connected with the connectors 1, 2 and 3 which in turn contact brushes 4, 5 and 6. These brushes engage conducting rings 7, 8 and 9 respectively, which are mounted on a rotor.
  • the conducting rings are provided with contact arms 10, 11 and 12, respectively, and these arms are adapted for engagement with contacts 13.
  • Low voltage spark plugs of the type previously referred to are included in a circuit from contacts 13 to ground 15 and each spark plug is in a separate combustion chamber as shown generally in dot-dash lines around one spark plug.
  • each spark plug 14 is connected with each of the three condensers 16 during one revolution of the rotor.
  • each spark plug is fired three times.
  • the number of sparks desired may be adjusted by varying the rate of rotation of the rotor.
  • the present invention provides an ignition circuit in which, in effect, three independent circuits exist for firing each spark plug. The safety features of such an arrangement are evident.
  • An ignition system for jet engines and the like in which a plurality of combustion chambers are provided, in combination, a spark plug of the creeping discharge type located in each of said combustion chambers, a plurality of ignition condensers, a rotor having a plurality of contact rings thereon, each of said contact rings being provided with a contact arm for connection with said spark plugs, and circuit means connecting each of said ignition condensers with one of said contact rings whereby each of said spark plugs is sequentially connected with each of said ignition condensers during one revolution of said rotor.
