Zusammenfassung:The present invention relates to an air control valve for a fuel cell vehicle, which can obtain advantageous effects of improving airtight properties and improving stability and reliability, by comprising: a valve housing having a first port and a second port; a first rotation shaft rotationally mounted on the valve housing and rotated by a driving source; a first valve member connected to the first rotation shaft, rotating about the first rotation shaft, and selectively opening and closing the first port; a second rotation shaft mounted on the valve housing to be rotatable relative to the first rotation shaft; a second valve member connected to the second rotation shaft, rotating about the second rotation shaft, and selectively opening and closing the second port; and a spring member having one end connected to the first rotation shaft and the other end connected to the second rotation shaft. 본 발명은 연료전지 차량용 에어 컨트롤 밸브에 관한 것으로, 제1포트 및 제2포트가 형성된 밸브 하우징; 밸브 하우징에 회전 가능하게 장착되며, 구동원에 의해 회전하는 제1회전축; 제1회전축에 연결되고, 제1회전축을 중심으로 회전하며 제1포트를 선택적으로 개폐하는 제1밸브부재; 제1회전축에 대해 상대 회전 가능하게 밸브 하우징에 장착되는 제2회전축; 제2회전축에 연결되고, 제2회전축을 중심으로 회전하며 제2포트를 선택적으로 개폐하는 제2밸브부재; 및 일단은 제1회전축에 연결되고 다른 일단은 제2회전축에 연결되는 스프링부재;를 포함하는 것에 의하여, 기밀 특성을 향상시키고, 안정성 및 신뢰성을 향상시키는 유리한 효과를 얻을 수 있다.
