The present invention relates to a fuel tank venting system, controlling a roll over valve using hydraulic pressure to block additional introduction of a fuel when the fuel is injected and securing continuous venting performance when the system is driven. The present invention realizes a new type of a roll over valve opening and closing operation method, enabling the roll over valve to be opened and closed while linked to pressure of the fuel injected through a pillar pipe of a fuel tank. The roll over valve is closed by the hydraulic pressure to prevent the fuel from being additionally injected when the fuel is injected, and the fuel tank is usually vented after the fuel is injected.

    본 발명은 연료주입 시 유압으로 롤 오버 밸브를 컨트롤하여 연료의 추가 주입을 막을 수 있고, 주행 시에는 상시 밴팅 성능을 확보할 수 있는 연료탱크 밴팅 시스템에 관한 것이다. 본 발명은 연료탱크의 필러 파이프를 통해 주입되는 연료의 압력과 연계하여 롤 오버 밸브의 개폐작동이 이루어지도록 한 새로운 형태의 롤 오버 밸브 개폐작동 방식을 구현함으로써, 연료 주입 시에는 유압에 의해 롤 오버 밸브가 닫혀지게 하여 연료의 추가 주입을 불가하게 하고, 연료 주입 종료 후에는 연료탱크의 밴팅을 상시 가능하게 하는 연료탱크 밴팅 시스템을 제공한다.
