A fuel supply system for a vehicle according to the present invention comprises: a fuel tank having a reserver installed in an internal space on one side thereof; and a sub-jet pump which is disposed in an internal space on the other side of the fuel tank, and uses a pressure difference created when fuel compressed by the fuel tank is discharged thereinto to discharge the fuel and fuel in the internal space on the other side of the fuel tank into the reserver. The sub-jet pump comprises: a nozzle member having an inflow unit to allow the fuel to flow thereinto from the fuel pump, and a spray unit formed on one end of the inflow unit and connected to the inflow unit to spray the fuel; and a diffuser member enclosing the spray unit and having a suction flow passage formed between the spray unit and the diffuser member, and an inlet and an outlet formed on one end and the other end of the suction flow passage, wherein an inflow direction and an outflow direction of the fuel through the inlet and the outlet are identical to each other.

    본 발명은, 일측 내부공간에 리저버가 설치된 연료탱크; 상기 연료탱크의 타측 내부공간에 마련되며, 연료펌프에 의해 가압된 연료가 토출되고, 연료 토출시 발생되는 압력차이를 이용하여 상기 연료탱크 타측 내부공간 내의 연료를 리저버 내로 함께 토출시키는 서브제트펌프;를 포함하며, 상기 서브제트펌프는, 상기 연료펌프로부터 연료가 유입되도록 유입부가 형성되며, 상기 유입부의 일단에 상기 유입부와 연통되어 연료를 분사하도록 분사부가 형성된 노즐부재; 상기 분사부를 감싸는 형상으로 마련되며, 상기 분사부와의 사이에 흡입유로가 형성되고, 상기 흡입유로의 일단부 및 타단부에 흡입구 및 토출구가 형성되며, 상기 흡입구 및 토출구를 통한 연료의 흡입방향 및 토출방향이 서로 동일하도록 구성된 디퓨져부재;를 포함하여 구성되는 차량용 연료 공급시스템이 소개된다.
