The present invention is fuel metering and atomizing valve for an internal combustion engine fuel supply device. The valve comprises a nozzle in which is formed an injection hole having an upstream chamber defining gradually decreasing areas towards the mouth of the injection hole for separating the fuel jet. The present invention provides an injection hole that is easy to machine and which effectively separates the fuel jet issuing from the chamber.

Fuel metering and atomizing valve for an internal combustion engine fuel

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.

Fuel supply circuit for an electromagnetically operated fuel injection

An electromagnetic injector featuring an anchor integral with a plunger and which is attracted, against the action of flexible means, towards a core having an electric winding; the injector itself presenting a casing housing the core and plunger, and which is divided, at the anchor, into two independent elements connected coaxially integral with each other, and between which is inserted a spacer element of nonmagnetic material, such as titanium or brass.
