Abstract

내관기관용 연료분사노즐은 심(12)을 거쳐서 노즐홀더(14)에 대해 단단히 조여지고 폐쇄용 스프링(27)의 힘에 의해 밸브시트(16)에 대해 가압되는 밸브니들(15)이 수용되어 있는 노즐체(11)를 갖는다. 일종의 나선형압축스프령으로서 설계되고 상기 노즐홀더에서의 블라인드홀(28)속에 배치되어 있는 상기 폐쇄용 스프링과 상기 밸브니들(15)의 사이에 있는 압력전달장치(30)는 단부평면(36,37)들을 갖는 평탄한 원통형 스프링판(31)과 상기 심(12)의 관통공(35)속에 이동이 가능하게 안내되는 원통형 추력스터드(32)를 포함한다.The fuel injection nozzle for the internal pipe is tightened against the nozzle holder 14 via the shim 12 and the valve needle 15 is pressed against the valve seat 16 by the force of the closing spring 27. It has the nozzle body 11. The pressure transmission device 30 between the valve needle 15 and the closing spring, which is designed as a kind of helical compression spring and disposed in the blind hole 28 in the nozzle holder, has end faces 36 and 37. And a cylindrical thrust stud 32 movably guided into the through hole 35 of the shim 12.
