The present invention relates to a gas pump gun shut-off control system for a fuel tank. An objective of the present invention is to provide a gas pump gun shut-off control system for a fuel tank which prevents a phenomenon in which a gas pump gun is shut off early before a fuel tank is completely filled when filling the fuel tank with gas. The gas pump gun shut-off control system for a fuel tank comprises: a fuel evaporation gas blocking unit mounted on a filler pipe of a fuel tank, and provided to separate an outer space of a fuel injection part of a gas pump gun inserted thereinto into a first space introducing outside air and a second space introducing fuel evaporation gas discharged from the fuel tank and block the inflow of fuel evaporation gas into the first space; a jet pump for outside air suction mounted on the fuel tank, and provided to suck outside air by receiving a portion of fuel sent by a fuel pump in the fuel tank as working fluid to discharge outside air into the fuel tank; and a jet pump connection hose provided to connect the first space and the jet pump for outside air suction to allow a flow of outside air.

    본 발명은 연료탱크의 주유건 셧오프 제어 시스템에 관한 것으로, 연료탱크에 주유 시 연료탱크가 만충되기 전에 주유건이 조기 셧오프되는 현상을 근본적으로 방지하는 연료탱크의 주유건 셧오프 제어 시스템을 제공하는 것에 목적이 있다. 이에 본 발명은: 연료탱크의 필러파이프에 장착되며, 그 내측에 삽입된 주유건의 연료주입부의 외측 공간을 외부공기가 유입되는 제1 공간과 상기 연료탱크에서 배출된 연료증발가스가 유입되는 제2 공간으로 분리하고, 상기 제1 공간에 연료증발가스가 유입되는 것을 차단하도록 구성된, 연료증발가스 차단유닛; 상기 연료탱크에 장착되며, 상기 연료탱크 내 연료펌프에서 송출되는 연료의 일부를 작동유체로 공급받음에 의해 외부공기를 흡입하여 상기 연료탱크의 내부로 토출하도록 구성된, 외부공기 흡입용 제트펌프; 상기 제1 공간과 상기 외부공기 흡입용 제트펌프를 외부공기의 유동이 가능하도록 연결하는, 제트펌프 연결호스;를 포함하는 연료탱크의 주유건 셧오프 제어 시스템을 제공한다.
