Abstract

Il existe déjà des bobines d'allumage munies de deux bobines primaires et de deux bobines secondaires qui sont enroulées sur un corps de bobine commun. Le corps de bobine commun comprend un canal traversant dans lequel est disposé un noyau de bobine commun. Cet arrangement permet de former deux circuits magnétiques comprenant respectivement une bobine primaire, une bobine secondaire et le noyau de bobine commun. La bobine primaire et la bobine secondaire de chaque circuit magnétique, vues en direction d'un axe longitudinal du corps de bobine, sont cependant à chaque fois disposées l'une au-dessus de l'autre. Ladite bobine d'allumage ne convient pas pour certains espaces de montage. L'invention permet de réduire l'espace de montage radial de la bobine d'allumage. Conformément à l'invention, toutes les bobines primaires (3) et toutes les bobines secondaires (4) sont disposées les unes derrière les autres sur un axe longitudinal du corps de bobine.
