Abstract

L'invention concerne les bougies d'allumage. Elle se rapporte à une bougie d'allumage dans laquelle un espace auxiliaire d'éclatemnt est formé à l'intérieur du trou de l'isolant, entre un tronçon interne 25 d'électrode centrale et une bille 30. Etant donné la forme de cette dernière, elle ne peut pas se mettre en biais dans le trou de l'isolant. Application à la réalisation de bougies d'allumage pour moteurs à bombustion interne.
