<p>A compressor has a suction throttle valve, which includes a suction passage, a suction port, a valve body, an urging member, a valve chamber, a first communication hole, a closing valve and a valve seat The closing valve closes the hole of the valve body by pressure difference between the valve chamber and the suction port. The valve seat limits movement of the closing valve toward the suction port. The hole of the valve body is closed when the closing valve is in contact with the valve body, and open when the closing valve is in contact with the valve seat. A communication passage is formed in the closing valve or the valve seat, which enables communication between the hole of the valve body and the suction port when the closing valve is in contact with the valve seat.</p> |
