Abstract: 본 발명은 차량의 피스톤 냉각용 체크 밸브에 관한 것으로서, 오일이 출입되기 위한 유입구 및 배출구가 형성된 밸브 하우징과; 오일압에 따라 상기 밸브 하우징의 내부에서 슬라이딩 이동되어 상기 배출구를 개폐하며, 상기 유입구로부터 유입된 오일이 상기 배출구로 빠지도록 내부에 오일 입구홀 및 오일 출구홀이 형성된 피스톤과; 상기 밸브 하우징의 내부에 마련되어 상기 피스톤을 상기 배출구가 폐쇄되는 방향으로 탄성 지지하는 스프링과; 오일압에 의해 상기 피스톤이 압축되는 경우, 상기 오일 출구홀의 오일이 상기 배출구로 배출되도록 상기 밸브 하우징에 상기 배출구와 연통되게 형성된 서브 배출유로를 포함하는 것을 특징으로 한다.
이에 의하여, 피스톤에 오일 입구홀 및 오일 출구홀이 형성되어 있기 때문에, 고속에서 갑자기 저속으로 변화가 있는 경우가 발생하더라도 오일이 오일 출구홀을 통해 배출구로 소정 시간 흐를 수 있으므로 유량이 급격히 떨어져 피스톤의 냉각 성능이 저하되는 것을 방지할 수 있다.-
