VALVOLA DI DOSAGGIO REGISTRABILE PER UN INIETTORE DI COMBUSTIBILE PER MOTORI A COMBUSTIONE INTERNA, E RELATIVO METODO DI REGISTRAZIONE.

摘要

The metering valve (24) is fitted in a hollow body (12) of the injector (11) and is controlled by the armature (27) of an electromagnet (26). The travel of the armature (27) towards the electromagnet (26) is arrested by a stop element (71) fittable to the hollow body (12) by means of a threaded element (68), which is screwed to a thread (18) of the hollow body (12) with a calibrated tightening torque to adjust the travel of the armature (27) towards the electromagnet (26) by means of the tightening torque. The method of adjustment includes the steps of fitting the stop element (71) in the hollow body (12) by means of a threaded element (68), and applying a calibrated tightening torque to the threaded element (68).
