ABSTRACT:
A piezoelectric igniter includes a piezoelectric transducer positioned adjacent the closed bottom of a cylindrical housing. A hammer of magnetic material is axially movably guided in the housing toward impact with the transducer. An axially movable actuating member is provided in the top of the housing and the hammer is biased by a compression spring disposed between the actuator and the hammer. The hammer is attracted and held in its rest position by a permanent magnet structure located within the compression spring, and is released and accelerated towards the transducer when the compressive force of the spring, when compressed by the actuator, exceeds the attraction of the permanent magnet during operation of the igniter. A spring between the hammer and transducer returns the hammer to its rest position after impact with the transducer. The hammer may comprise an iron cup filled with lead.
