Which process compromises lubricant delivery inside reciprocating pumps in refrigeration units?

💡 Explanation

Refrigerant dissolved within lubricating oil can vaporize during low-pressure stages; this creates vapor-lock obstructing the oil pump because reduced density compromises its pumping ability, therefore lubricant starvation occurs rather than proper lubrication.
