Abstract
The valve comprises a shutter for the drain conduit of the control chamber of the injector; and an electromagnet having a fixed core with a seat for a coil which is energized to operate the armature controlling the shutter. The core presents two coaxial annular pole pieces, the outer one of which is shorter than the inner one and fitted with a ring of magnetic material partially closing the seat and enabling a substantial reduction in the diameter and, hence, the hydraulic resistance and mass of the armature.
