Definitions

  • piezoelectric unit which is manufactured without any special diiculty and assuredly produces a spark required for the ignition of gas when it is used in a gas igniter.
  • the essential component elements required for composing a high voltage generating device utilizing a piezoelectric element include a striker or a hammer for striking the piezoelectric element, means for causing said striker to accumulate an energy required for said striking, and means for letting said accumulated energy release in a moment to make the striker hit hard the piezo element.
  • Conventional means for causing said striker to accumulate the energy include a coil spring and an operating lever engaged to said striker. In such means, the energy is accumulated in the striker by displacing it, by means of an operating body engaged to it, in such a manner that the coil spring is either compressed or expanded by the displacement of the striker.
  • the operating body is provided with a rod which can be projected from the operating body in a direction orthogonal to the direction of travel of the operating body and through which the operating body is engaged to the striker.

  • a piezo unit is fabricated in the following manner. That is; iirst an electrode plate is inserted into the central portion of a cylindrical case, and then a piezo element and a buffer plate is inserted to each side of the electrode.

With such an arrangement, however, the impact given by the striker is mostly absorbed by the case, thus reducing so much energy to be given to the piezo elements. Therefore, the voltage produced by such a unit is usually comparatively low.
