Title (EN) COIL ASSEMBLY
(FR) ENSEMBLE DE BOBINE
Abstract:
(EN) Coil assembly (28) in a fuel injector (10) comprising: - a magnetic core (38); - a winding (40) wound around the core (38), the winding (40) being overmoulded and forming a cylindrical overmoulding (42); and - the overmoulded coil assembly (28) additionally comprising an axial blind hole (50) extending towards the interior of the coil assembly (28) from the first surface (51) to a distal end (52), the blind hole (50) being suitable for housing at least one spring (54, 56) for loading a magnetic armature (30). The coil assembly (28) is provided with a degassing hole (58) passing through the core (38) and the overmoulding (42) from the blind axial hole (50) to an axial outer cylindrical surface (60), the degassing hole (58) being provided in the magnetic core (38) and having a restriction that is arranged in a first section (62) that is proximal to the blind axial hole (50).
(FR) Ensemble de bobine (28) dans un injecteur de carburant (10) comprenant: - Un noyau magnétique (38), - Une bobinage (40) enroulé autour du noyau (38), le bobinage (40) étant surmoulé formant un surmoulage cylindrique (42), et - L'ensemble de bobine surmoulé (28) comprenant de plus un trou borgne axial (50) s'étendant vers l'intérieur de l'ensemble de bobine (28) à partir de la première surface (51) à une extrémité distale (52), le trou borgne (50) étant adapté pour loger au moins un ressort (54, 56) pour solliciter une armature magnétique (30). L'ensemble de bobine (28) est muni d'un trou de dégazage (58) traversant le noyau (38) et le surmoulage (42) à partir du trou axial borgne (50) jusqu'à une surface cylindrique externe axiale (60), le trou de dégazage (58) ménagé dans le noyau magnétique (38) et présentant une restriction agencée dans un premier tronçon (62) proximal du trou axial borgne (50).
