Abstract
The metering valve is fitted in a hollow body of the injector and is contled by the armature of an electromagnet. The travel of the armature towards the electromagnet is arrested by a stop element fittable to the hollow body by a threaded element, which is screwed to a thread of the hollow body with a calibrated tightening torque to adjust the travel of the armature towards the electromagnet according to of the tightening torque. The method of adjustment includes the steps of fitting the stop element in the hollow body by a threaded element, and applying a calibrated tightening torque to the threaded element.
