The present invention relates to a check valve (10) for a compressor. In the check valve (10) for a compressor, a valve body (15) comprises a contact surface (15d) and an outer circumference surface (15c). A valve hole (12) includes a large diameter part (12a) and a small diameter part (12b). An intercommunicating window (14) has a shape of an opening area gradually becoming larger from a valve sheet. An open state is formed as a contact area is separated from the large diameter part, and an outer circumference surface opens the intercommunicating window. A fully closed state is formed as the contact surface closes the large diameter part, and the outer circumference surface blocks intercommunication through the intercommunicating window. A buffering state is formed as the contact surface is separated from the large diameter part, and the outer circumference surface blocks intercommunication through the intercommunicating window. A hunting phenomenon is inhibited, and the operation of the valve body (15) is stabilized. |
