According to the present invention, disclosed is a check valve of a variable capacity compressor for a vehicle. According to the present invention, a bypass flow path is formed in an internal side surface of a lower end of a valve case to selectively use a valve sheet. Moreover, when a spool valve is initially opened for refrigerant to be introduced, valve noise generated between the valve case and the spool valve can be reduced, and a wobble phenomenon of the spool valve can be effectively prevented to maintain an advantage of a preceding patent.

    본 발명은 차량용 가변용량 압축기의 체크밸브를 개시한 것으로, 이러한 본 발명은 밸브케이스의 하단 내측면에 바이패스 유로를 형성한 것이며, 이에따라 밸브시트 사용이 선택적으로 이루어질 수 있도록 함은 물론, 스풀밸브의 초기열림으로부터 냉매 유입시 밸브케이스와 스풀밸브 사이에서 발생되는 밸브소음을 줄일 수 있도록 하면서도 선행특허의 장점인 스풀밸브의 떨림현상을 효과적으로 방지할 수 있도록 한 것이다.
