The present invention discloses a check valve of a variable-capacity compressor for a vehicle and, more specifically, is constructed to have a higher height of a front side than a rear side of a valve seat. As such, a spool valve mounted on the valve seat is installed to be inclined inside a valve housing, such that initial opening of the spool valve is performed by a minimal contact to the valve housing in a state where the spool valve is inclined, thus preventing a valve noise generated between a valve case and the spool valve, and also effectively restraining an initial shaking phenomenon while a passage is opened quickly, when a refrigerant starts to flow in after the initial opening of the spool valve.

    본 발명은 차량용 가변용량 압축기의 체크밸브를 개시한 것으로, 이러한 본 발명은 밸브시트의 전방측을 후방측보다 그 높이를 높게 구성한 것으로, 이를 통해 밸브시트 위에 올려지는 스풀밸브가 밸브하우징내에서 경사지게 설치하여 스풀밸브의 초기열림이 기울어진 상태에서 최소 접촉으로 이루어져 밸브케이스와 스풀밸브 사이에서 발생되는 밸브소음을 방지함은 물론, 스풀밸브의 초기 열림으로부터 냉매 유입이 이루어질 때 유로 개방이 신속하게 이루어지면서 초기 떨림 현상을 효과적으로 억제한 것이다.
