Abstract
Intorno alla porzione dell'elettrodo centrale (4) che emerge dall'elemento isolante (3a, 3) è disposto un elemento anulare (10) costituito da un bilaminato presentante un primo strato (10a) in materiale nobile ed un secondo strato (10b) di metallo non nobile, quale nichel o sue leghe, in relazione di conduzione elettrica con detto elettrodo centrale (4), in modo tale per cui nel funzionamento la scintilla o le scintille si innescano fra tale elemento anulare (10) e l'elettrodo o gli elettrodi di massa (9). (Figura 3).
