According to the present invention, disclosed is a check valve of a variable capacity compressor for a vehicle. According to the present invention, an upper surface of a valve case is opened and then a lid is coupled and formed thereto, wherein a valve sheet having a refrigerant inlet at the valve case is in an integrated state. By eliminating the valve sheet, an insertion coupling of a spool valve is possible at an upper portion of the valve case, thereby simultaneously improving overall assembling efficiency of the check valve, reducing a valve noise occurring in between the valve case and the spool valve when taking in a refrigerant from an initial opening of the spool valve, and preventing a trembling phenomenon of the spool valve which is strength of the preceding patent.

    본 발명은 차량용 가변용량 압축기의 체크밸브를 개시한 것으로, 이러한 본 발명은 밸브케이스에 냉매유입구를 형성한 밸브시트를 일체화시킨 상태에서, 밸브케이스의 상면을 개구한 후 이에 덮개를 결합 구성한 것이며, 밸브시트를 없애면서 밸브케이스의 상부에서 스풀밸브의 삽입 결합이 이루어지도록 하여 체크밸브의 전반적인 조립성을 개선하는 동시에, 스풀밸브의 초기열림으로부터 냉매 유입시 밸브케이스와 스풀밸브 사이에서 발생되는 밸브소음을 줄일 수 있도록 하면서, 선행특허의 장점인 스풀밸브의 떨림현상을 효과적으로 방지할 수 있도록 한 것이다.
