재연기관용 연료분사펌프Fuel injection pump for reburn engine

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 때형 엔진에의 사용을 위한 연료분사 펌프의 실린더 및 펌프 피스톤에 대한 본 발명의 실시예를 도시한다.1 shows an embodiment of the invention for a cylinder and pump piston of a fuel injection pump for use in a timed engine.

Claims (2)

재연기관 특히 대형 엔진에 사용하기 위한 연료분사 펌프에 있어서, 펌프 피스톤(3)은 분말 야금법에 의해 제조된 내화성 고속도강으로 구성되며, PVD법에 의해 약 2 내지 4㎛두께의 티탄 질화물(TiN) 층(7)으로 최소한 그 가동부 혹은 운동부가 코우팅된 것을 특징으로 하는 연료 분사펌프.In fuel injection pumps for use in re-combustion engines, especially large engines, the pump piston (3) consists of refractory high-speed steel produced by powder metallurgy and has a titanium nitride (TiN) of about 2-4 μm thickness by PVD. A fuel injection pump, characterized in that at least its movable or moving part is coated with a layer (7). 제1항에 있어서, 티탄질화물층(7)은 정확히 2 내지 3㎛의 층두께를 갖음을 특징으로 하는 연료분사펌프.Fuel injection pump according to claim 1, characterized in that the titanium nitride layer (7) has a layer thickness of exactly 2-3 m. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
