What happens to a flexible reed valve under excessive cylinder temperatures?

When a flexible reed valve is subjected to excessive cylinder temperatures, it tends to bend. The reed valve is designed to open and close in response to pressure changes, and it relies on the ability to return to its original position after being displaced. High temperatures can alter the material properties of the reed, making it more susceptible to deformation.

Under excessive heat, the reed valves can lose their rigidity, which allows them to bend rather than maintaining a straight or flat form. This bending can lead to improper sealing or failure to close fully, resulting in decreased system efficiency and potential damage to the refrigeration system. The ability to bend is a critical characteristic of the valve operation, but at extreme temperatures, this physical change can lead to operational issues.

Understanding this principle helps in diagnosing problems related to valve performance in refrigeration systems and underscores the importance of managing cylinder temperatures to ensure the reliability of the equipment.
