The fuel injector comprises a solenoid (9), wound around a bobbin (3), which can be energized through electrical connections (10), a guideless magnetic valve member (7), a valve seat (6), a magnetic core (5), at least one magnetic coupling element (2), a fuel inlet tube (8) and an external housing (1). The guideless magnetic valve member (7), the valve seat (6), the magnetic core (5), the at least (1) magnetic coupling element (2), the solenoid (9), the bobbin (3) and the electrical connections (10) form an electromagnetically autonomous subassembly which comprises the entire magnetic circuit and also all the electrical components of the finished injector. The solenoid (9) and bobbin (3) are lodged in a space defined between the at least one magnetic coupling element (2) and the magnetic core (5), and the subassembly is possibly tested and calibrated extensively prior to the obtention of the finished fuel injector.
