The present invention relates to an automobile fuel tank sealing valve. An objective of the present invention is to provide the automobile fuel tank sealing valve. A configuration for opening and closing operation of the fuel tank sealing valve comprises: a pushbutton having a guide slot; and a button housing having a guide pin. Accordingly, open and closed positions of the valve may be maintained in a status in which a power is not applied. As a result, continuous supply of a current to a coil can be interrupted and battery discharge can be prevented. Also, according to the present invention, sudden change in a pressure in a fuel tank can be prevented by opening the sealing valve in a two-stage operation.
본 발명은 연료탱크 밀폐밸브의 개폐 작동을 위한 구성으로 가이드 슬롯을 갖는 푸시버튼 및 가이드 핀을 갖는 버튼 하우징을 채택하여, 전원 미인가 상태에서 밸브의 열림 및 닫힘 위치가 유지될 수 있도록 함으로써, 코일에 전류가 계속 공급되는 것을 차단하여 배터리 방전을 방지할 수 있고, 밀폐밸브의 열림이 2단 작동으로 이루지도록 함으로써, 연료탱크의 급격한 압력 변화를 방지할 수 있도록 한 자동차용 연료탱크 밀폐밸브를 제공하고자 한 것이다.
