Abstract (en)

[origin: WO2018041656A1] 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).
