PROCEDIMENTO PER LA PRODUZIONE DI SPIGOLI PILOTA SU UNA VALVOLA, PREFERIBILMENTE UNA VALVOLA PER INIETTORE DI CARBURANTE DI UN MOTORE A COMB

摘要

The invention relates to a method for machining control edges of a valve, preferably of a valve for a fuel injection device of an internal combustion engine, with the fuel injection device having at least one piston with control edges which co-operate with control edges fixedly connected to a valve, wherein respectively co-operating control edges are machined in one single machining operation with the aid of one single tool. The invention also relates to a fuel injection device with a valve which has control edges machined according to this method and which activates at least one injection valve body for closing off nozzle openings, wherein the valve is controlled by a control unit and is equipped with working connections by which a pressure medium is supplied to a control piston for displacing the injection valve body.
