Zusammenfassung: | The present invention relates to a fuel pump module for liquefied petroleum injection (LPI), comprising: a fuel pump to pump and transfer fuel stored in a fuel tank towards an engine; a reservoir cup coupled to outer and lower surfaces of the fuel pump, reducing operational noise generated by fuel flow due to pumping operation of the fuel pump, and filling the fuel stored in the fuel tank in the inside to supply the fuel to the fuel pump; and a check valve to perform opening/closing operation to fill the fuel in the inside of the reservoir cup and prevent the filled fuel from coming out. Accordingly, since the reservoir cup is coupled to cover the outer and lower surfaces of the fuel pump, a filling space filled by the fuel is increased, thereby minimizing the fuel flow during the pumping operation of the fuel pump to reduce operational noise.
엘피아이용 연료펌프모듈에 관한 것으로, 연료탱크에 저장된 연료를 엔진 측으로 송출하도록 펌핑하는 연료펌프, 상기 연료펌프의 외측면과 하면에 결합되고 상기 연료펌프의 펌핑 동작에 의한 연료의 유동에 의해 발생하는 동작소음을 저감하며 상기 연료탱크에 저장된 연료를 내부에 충진시켜 상기 연료펌프로 공급하는 리저버 컵 및 상기 리저버 컵 내부에 충진하고 충진된 연료가 외부로 유출되는 것을 방지하도록 개방 및 폐쇄 동작하는 체크밸브를 포함하는 구성을 마련하여, 연료펌프의 외측면과 하면을 커버하도록 리저버 컵을 결합해서 연료가 충진되는 충진공간을 증대함에 따라, 연료펌프의 펌핑 동작시 연료 유동을 최소화해서 동작 소음을 저감할 수 있다는 효과가 얻어진다. |
