Abstract: A fuel injector has an injector body extending along a given axis; a tubular valve body housed inside a hole in the injector body and coaxial with the injector body; and an annular chamber defined by the injector body and the valve body. The method of producing the injector includes connecting the valve body to the injector body, and fixing the valve body in a given position along the axis with respect to the injector body by means of a driving operation to interference fit the valve body inside the hole in the injector body.

Abstract: The injector has a hollow body supporting an ordinary injection nozzle and a metering valve for metering the fuel to be injected; and a support defined by a sleeve and by an end wall. The sleeve houses an electromagnet controlling the metering valve, and is fitted to the hollow body. For which purpose, there is provided a leaf spring having a ring-shaped portion engaging the end wall of the support; and a number of elastic blades, each terminating with a hook-shaped appendix which engages a corresponding retaining element on the hollow body.

Abstract: The injector has a hollow body housing a fuel metering valve closed by a closing spring; and a support housing an electromagnet controlling an armature. The support is connected to the hollow body, and the armature provides for opening the valve. The armature is fitted inside the hollow body by means of a leaf spring hinge having an annular portion fixed between the hollow body and the support, and a projecting radial tongue fixed to a central portion of the armature. The tongue, together with at least one radial appendix of the leaf spring hinge, provides for arresting the armature with a predetermined clearance with respect to the core of the electromagnet.
