Breakerless magneto device

A magneto ignition system for use with an internal combustion engine comprising:

• means including at least two magnetic circuits for a varying flux field having a single rotor and first and second cores respectively with a first winding mounted on said first core for generating a voltage potential and a second winding mounted on said second core for generating a trigger signal,
• said second core and said second winding being positioned next adjacent and parallel to a portion of said first core and inside said first winding,
• engine fuel igniting means for igniting combustible fuel in said engine, and
• means for selectively causing said voltage potential generated in said first winding to be applied to said igniting means, said means being connected to said second winding and responsive to the trigger signal for causing said voltage potential to be applied to said igniting means.

A magneto ignition system comprising:

• a core structure including a first core having a magneto coil mounted thereon and a trigger core positioned inside said magneto coil next adjacent said first core and having a trigger winding mounted thereon, said trigger core and winding being spaced from said first core,
• a rotor structure having a permanent magnet thereon, said rotor producing a varying flux through said first and second cores,
• means for completing a circuit through said magneto coil, and
• means responsive to the voltage generated in said trigger winding by said varying flux for interrupting the flow of current through said circuit.
