Abstract
The valve comprises a casing and an injection nozzle fixed to this and provided with at least one fuel injection orifice and a shutter member movable under the action of an electromagnet and adapted to control the passage of fuel through the injection orifice, this shutter member being provided with an active surface adapted to engage on a corresponding seat of the nozzle in which the injection orifice is located; the valve is characterized by the fact that it includes passages for supplying fuel to the injection orifice from a region outside the valve, which are formed substantially in a region which is disposed peripherally around the first-defined seat and which lies substantially in a plane perpendicular to the axis of the valve and containing the seat itself.
