Abstract
Procédé de conformation (100) d'une vanne d'injecteur (31), la vanne (31) comprenant un siège (34) et un obturateur (35) adapté à coulisser dans un alésage (26). Le siège (34) définit une face femelle conique (50) et l'obturateur (35) définissant une face conique mâle (28). Le procédé de conformation (100) comprend les étapes suivantes : a/ pourvoir (110) le corps de buse (16) dans lequel la face femelle (50) du siège (34) est ébauchée, b/ pourvoir (120) l'aiguille (14) dans lequel la face male (28) de l'aiguille est ébauchée, d/ insérer (140) l'aiguille (14) dans l'alésage (32) du corps de buse caractérisé en ce que le procédé de conformation (100) comprend de plus une étape : e/ mettre en forme (150) et finir les faces coniques (28,50) du siège et de l'aiguille en les conformant simultanément par application d'une force axiale (F) sur l'aiguille (14).
