Abstract
The valve comprises a shutter for the drain conduit of the control chamber of the injector; and an electromagnet having a fixed core, and an armature controlling the shutter and which is normally pushed by a return spring for maintaining the drain conduit closed by the shutter. The device for adjusting the travel of the armature comprises a plate which is fitted to the body of the injector by means of a sleeve and via the interposition of two sets of calibrated washers. The plate presents a stop element against which is arrested a contact element integral with the armature, for preventing the armature from contacting the core.
