What is the function of a safety head on a compressor?

Explanation:
The function being tested is protective and focused on preventing damage from liquid slugging. A safety head provides a controlled relief path in the compressor head so that if liquid refrigerant enters the cylinder, a small amount of vapor can escape before the liquid slug can slam into the valve plate. This helps prevent bending or damage to the valve plate, which can occur when liquid refrigerant is compressed. This device isn’t about lubricating moving parts, measuring discharge temperature, or controlling motor speed, which is why the other options don’t fit as well.
