Description

내연기관용 연료분사기Fuel injector for internal combustion engine

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음This content is subject to disclosure, so the full text is not included.

제1도는 본 발명에 의한 분사기 하부의 길이 방향의 단면도.1 is a cross-sectional view in the longitudinal direction of the lower portion of the injector according to the present invention.

제2도는 제1도에 표시한 분사기에서 노쥴침이 약간 열린상태도.Figure 2 is a state in which the nodule needle is slightly open in the injector shown in Figure 1.

제3도는 제1도에 표시된 분사기에서 노쥴침이 거의 열린상태도.Fig. 3 is a diagram showing the state where the nodule needle is almost open in the injector shown in Fig. 1.

제4도는 본 발명에 의한 분사기의 다른 실시예에서 분사기 하부의 길이 방향 단면도.4 is a longitudinal sectional view of a lower portion of the injector in another embodiment of the injector according to the present invention.

Claims (7)
