Abstract

공지된 전자 작동식 밸브에서는 밸브 니들이 관형상의 가동자와, 슬리브상의 결합관과, 밸브 폐쇄부재로 구성되어 있다. 이런 경우에 연료는 밸브 니들의 내부를 유동하여 밸브 폐쇄부재까지 도달하고, 이어서 밸브니들에 설치된 가로방향 구멍을 걸쳐 밸브시트의 방향에 유출된다.
본 발명에 의한 밸브 니들(18)은 밸브 니들(18)의 적어도 밸브 니들 구분(19)과 밸브 폐쇄부재 구분(24)의 디프드로잉 성형에 의해 일체의 구성부분으로 제조된다는 우수한 점이 있다. 밸브시트의 방향으로의 연료의 유동을 보증하기 위해서는 밸브 니들 구분(19)에, 예컨대 2개의 압박부(61)가 설치되며, 반구형 쉘 형상을 갖는 밸브 폐쇄부재 구분(24)에는 평평한 면취부(25)가 가공성형 되어 있다. 즉, 연료는 밸브의 니들 구분(19)의 외주면을 따라 유동된다. 본 발명에 의한 밸브 니들은 혼합기 압축형의 불꽃 점화 내연기관의 연료 분사장치에서의 연료 분사 밸브를 위해 특히 적합하다.
