Abstract

본 발명은 기관의 연료분사장치에 관한 것으로서, 인젝터로부터 흡기관 내로 연료가 누설되는 것을 방지하기 위해, 연료탱크에 형성되는 연료토출통로(1)에 연료복귀통로(2)가 연통되게 형성되어, 상기 연료복귀통로에 토출을 규제하는 제1체크밸브(3)가 장착되고, 상기 연료토출통로에 연료의 되돌아감을 규제하는 제2체크밸브(4)가 장착되는 연료분사식 기관의 연료압력 저감장치이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel injection device of an engine, in which a fuel return passage (2) is formed in communication with a fuel discharge passage (1) formed in a fuel tank in order to prevent leakage of fuel from an injector into an intake pipe. A fuel pressure reducing device of a fuel injection engine is provided with a first check valve (3) for regulating discharge in the fuel return passage, and a second check valve (4) for regulating the return of fuel to the fuel discharge passage. .
