Abstract

Procédé de production d’un canal dans un dispositif d’injection de carburant selon lequel on réalise, dans le corps (30) de ce dispositif, un canal (32) ou (32’), débouchant par une embouchure dans une cavité (33), on dispose une électrode (34) dans la cavité, cette électrode étant munie d’une zone dénudée (34A) ou (34A’), en regard de cette embouchure, et on applique une différence de potentiel entre ce corps et cette électrode, en présence d’un électrolyte en circulation dans la cavité en sorte d’ébavurer par électro-érosion chimique la périphérie de cette embouchure. L’ébavurage de plusieurs embouchures peut être réalisé simultanément, avec la formation d’un éventuel lamage sur une partie au moins de la périphérie de ces embouchures.
