ABSTRACT:
The injector has a hollow body having an injection nozzle controlled by a ntrol rod movable axially by a metering valve controlled by an armature of an electromagnet. The metering valve has a control chamber having a pressurized-fuel inlet conduit and a surplus fuel drain conduit. To reduce the length of the injector, the inlet conduit is coaxial with the rod and communicates with a coaxial cavity fed with fuel from the top; the drain conduit is radial with respect to the axis of the rod, and the armature is also movable radially; the armature and the electromagnet are housed in an arm which is also radial with respect to the axis of the rod; and the cavity has a conical portion in which a bulb-shaped portion of a fitting of a supply conduit is fitted by means of a ring nut.
