Abstract

L'invention concerne un dispositif de transformation servant à générer une tension d'allumage pour des moteurs à combustion interne. Ce dispositif de transformation comprend un enroulement primaire (12), un enroulement secondaire (26), un noyau ferromagnétique (28), et une électrode (32) qui est opposée à une extrémité (38) du noyau (28), qui est reliée avec l'enroulement secondaire (26), et qui peut être reliée avec un éclateur. Ladite extrémité (38) du noyau ferromagnétique comporte une transition à courbure continue entre la surface latérale et la face.
