Abstract

Bobine d'allumage comprenant: un élément de noyau en fer et en forme de C (100) définissant un entrefer entre les extrémités therminales dudit élément; un sous-ensemble de bobines à l'intérieur dudit entrefer comprenant un élément de bobine primaire (200) et un élément de bobine secondaire (400); ledit élément de bobine primaire (200) et ledit élément de bobine secondaire (400) comprenant chacun un bobinage et une pluralité d'enroulements en matériau électromagnétique enroulés autour de l'axe de chacun desdits bobinages, ledit élément de bobine primaire (200) logeant télescopiquement à l'intérieur dudit élément de bobine secondaire (400); ledit élément de bobine primaire (200) comprend un aimant permanent (310) situé à une extrémité dudit bobinage (200) et en contact étroit avec ledit élément de noyau en forme de C (100) à ses deux extrémités, remplissant, de ce fait, complètement ledit entrefer, ledit aimant permanent (310) étant fabriqué en matériau magnétique dispersé à l'intérieur d'une matrice non conductrice électriquement et présentant une densité sensiblement inférieure à la densité totale à l'intérieur de ladite matrice.
