Abstract

Each device in the series is formed by connecting together a first (1) and second (24) assembly. The first assembly (1) substantially comprises a body (2) defining a chamber (3) housing an annular electromagnet (4) and a tubular core (5) coaxial with the electromagnet. The second assembly (24) comprises a nozzle (25) in which is formed at least one fuel injection hole (26), a plunger (27) for controlling fuel passage through the injection hole, and a tubular anchor (28) secured to the plunger.
