Claims (1)

  1. 본문에 상술하고 도면에 도시한 바와 같이, 상부에 적어도 하나의 나선형 램프(ramp)가 이루어져 있는 플런저가 하사점과 상사점 사이에서 왕복운동함에 따라 용적인 변하는 원통형체 속의 연료 유입실로 통해 있는 동시에 비교적 낮은 압력의 연료 공급원으로 연결된 연료유입구가 상사점으로 움직이는 플런저에 의해 막함으로써 연료 유입실로 부터 기관 실린더에 결합된 분사기로 연료가 배출되도록 되어있는 분사펌프에 있어서, 그 개량점이 플런저에 연료 유입실에서 연료 공급원과 원통형체의 내부 공간을 연결하는 적어도 한개의 연료 유입관으로 통할 수 있도록 한 통로를 형성시켜 플런저가 상사점으로 움직이는 중의 어느 기정된 순간으로부터 기정된 시간 동안 연료 유입실로부터 상기한 분사기로 연료가 배출되지 못하도록 함으로써 제1배출 위상에서는 연료가 기관 실린더속으로 예비-분사되도록 하는 반면에 제2위상에서는 주연료 분사가 이루어지도록 한다는데에 있는, 내연기관 실린더속으로 연료를 분사시키기 위한 분사펌프.
