Title (EN) FUEL INJECTION PUMP INCLUDING A VARIABLE PRESSURE COMPARTMENT
(FR) POMPE D'INJECTION DE CARBURANT COMPRENANT UN COMPARTIMENT À PRESSION VARIABLE
(KO) 가변 압력실을 가지는 연료분사펌프
Abstract: front page image
(EN)The present invention relates to a fuel injection pump including a variable pressure compartment which has a simpler constitution and lower manufacturing cost than typical fuel injection pumps without using a separate barrel-moving device and without modifying the shape of the plunger, and which controls fuel injection timing according to engine loads. The fuel injection pump including the variable pressure compartment further includes a pressure adjustment member that includes: a tight contact plug the lower end of which is inserted in an upper cover; a cylinder, the lower end of which is inserted into the tight contact plug and which includes the variable pressure compartment therein; a main hole for pressurizing fuel disposed on the upper cover and a barrel for connecting the variable pressure compartment and the plunger insertion hole of the barrel to each other; a piston sliding vertically within the variable pressure compartment; and a height-adjustable part for manually adjusting pressure, which is disposed at the upper end of the cylinder so as to elastically support the upper end of the piston.
(FR)La présente invention se rapporte à une pompe d'injection de carburant comprenant un compartiment à pression variable qui présente une constitution plus simple et un coût de fabrication plus faible que les pompes d'injection de carburant habituelles sans utiliser de dispositif de déplacement de corps distinct et sans modifier la forme du plongeur, et qui commande le moment d'injection de carburant en fonction des charges du moteur. La pompe d'injection de carburant comprenant le compartiment à pression variable comprend en outre un organe de réglage de pression qui comprend : un bouchon de contact ajusté dont l'extrémité inférieure est introduite dans un couvercle supérieur ; un cylindre, dont l'extrémité inférieure est introduite dans le bouchon de contact ajusté et qui contient le compartiment à pression variable ; un trou principal pour mettre sous pression le carburant disposé sur le couvercle supérieur et un corps pour relier le compartiment à pression variable et le trou d'introduction de plongeur du corps l'un à l'autre ; un piston coulissant verticalement dans le compartiment à pression variable ; et un élément à hauteur réglable destiné à régler manuellement la pression, qui est disposé au niveau de l'extrémité supérieure du cylindre de manière à soutenir élastiquement l'extrémité supérieure du piston.
(KO)본 발명은 별도의 배럴을 이동시키는 장치가 없을 뿐만 아니라 플런저의 형태 변형 없이도 종래의 연료 분사펌프 보다 간단한 구성과 저렴한 제작비용으로 엔진 로드별로 연료 분사시기를 조절할 수 있도록 하는 가변 압력실을 가지는 연료 분사펌프에 관한 것이다. 상기 가변 압력실을 가지는 연료 분사펌프는, 상부 커버에 하단부가 삽입 설치되는 밀착 플러그; 상기 밀착 플러그에 하단부가 삽입 설치되며 내부에 가변 압력실이 형성되는 실린더; 상기 실린더의 가변 압력실과 배럴의 플런저 삽입 홀을 서로 연통시키도록 상기 상부 커버와 배럴에 형성된 메인 연료 가압 홀; 상기 실린더의 가변 압력실에 상하 슬라이딩 이동 가능하도록 설치되는 피스톤; 및 상기 피스톤의 상단부를 탄성 지지하도록 상기 실린더의 상단부에 상하 높이 조절 가능하게 설치되는 수동 압력 조절부;로 구성된 압력 조절수단을 더 포함하여 구성된다.
