摘要：
Normally closed valve structure is located in a fluid path between the suction and discharge sides of a compressor. The valve structure opens upon a small pressure differential when the higher pressure is in the normal suction side which is indicative of reverse operation. Additionally, relief valve structure opens when the discharge pressure becomes excessive.
