A fuel injector (1) for an internal-combustion engine comprises an injector body (2) and an injection-control valve (12), which in turn comprises: an open/close element (18); an elastic thrust element (20) for pushing the open/close element (18); and a solenoid actuator (21), which can be actuated for exerting an action countering the thrust exerted by the elastic element (20). The solenoid actuator (21) is formed by a monolithic assembly (53) obtained in a mould (50), in which there is injected, on a core (23) and a coil (24) coupled to one another, a plastic material, which defines, once it has solidified, a body (28) for insulation of the core (23) from the injector body (2) and which forms, once it has solidified, a monolithic assembly with the core and the coil. |
