본 발명은 차량용 연료탱크 차단밸브에 관한 것으로, 제1밸브와 제2밸브가 기구적으로 걸려서 연동됨으로써 제2밸브 구동용 스프링을 별도로 구비할 필요가 없다. 따라서 부품수가 감소되고, 내부 구조가 단순해지며, 이에 비용 및 공수가 감소되는 효과가 있다.

    A fuel tank isolation valve for a vehicle includes a drive unit having a solenoid coil; a flow path unit having a vaporized fuel gas flow path; a valve assembly configured to open or close the flow path in the flow path unit by being operated by the drive unit, where the valve assembly includes: a first valve configured to open the flow path by being operated by a magnetic force generated by the coil; and a second valve configured to open the flow path while operating in conjunction with the first valve by being caught by the first valve when the first valve operates. The first valve and the second valve may operate in conjunction with each other by being mechanically caught, such that it is not necessary to provide a separate spring for operating the second valve.
