发明名称 processo para a produção de furos de estrangulamento com ponto de transferência de cavitação baixa
摘要 A method for producing a throttle point, particularly in a channel of a valve piece of a fuel injector is disclosed. The following are performed: first, the outlet channel is created by machining. Then, the throttle point is stamped by a stamping die inserted into a guide hole. The pre-stamped throttle point is electrical-discharge machined in such a way that said throttle point has an electrical-discharge machined inlet area and comprises a stamped outlet area, which lies before a continuous cross-section expansion of the outlet channel as viewed in the flow direction.
