How do the valves on a compressor operate?

Compressor valves primarily operate based on pressure differentials. In a refrigeration system, these valves are designed to open and close in response to varying pressures within the compressor. When the pressure inside the compressor cylinder decreases, the valve will open, allowing refrigerant vapor to enter. Conversely, when the pressure inside the cylinder increases upon compression, the valve will close, preventing the refrigerant from escaping during the compression cycle.

This pressure-based operation is essential for maintaining the proper function of the refrigeration cycle, as it ensures that the compressor effectively draws in refrigerant and compresses it to the desired pressure levels. Understanding how these valves operate is crucial for diagnosing compressor issues and maintaining system efficiency.
