A cylinder head in place by a spring is referred to as what?

The term "safety head" refers to a cylinder head that is secured in place by a spring mechanism, particularly in refrigeration and air conditioning systems. This setup is crucial for maintaining safety in pressurized systems. The spring enables the cylinder head to respond to pressure changes by allowing for the release of pressure when it exceeds a predetermined limit, thereby preventing potential overpressure scenarios.

In this context, the safety component is essential for avoiding ruptures or other hazardous situations within a refrigeration system. It is designed to function automatically, engaging when necessary to ensure safe operation. Therefore, the correct identification of this type of cylinder head as a safety head is due to its role in safeguarding the system and promoting reliable performance.
