Which compressor type may incorporate safety springs for liquid management?

Reciprocating compressors are designed to compress refrigerants and other gases using a piston within a cylinder, much like an engine. One of the critical aspects of their operation involves managing liquids that may enter the compressor. If liquid refrigerant enters, it can cause hydraulic lock, potentially damaging the compressor. To mitigate this risk, some reciprocating compressors incorporate safety springs specifically for liquid management. These springs help manage and expel any incompressible liquid from the system, allowing only vapor to be compressed and ensuring safe operation.

Other types of compressors, like rotary, scroll, and centrifugal compressors, operate on different principles that may handle liquid differently or may use alternative mechanisms for liquid management. Consequently, the use of safety springs is particularly relevant to the design and operation of reciprocating compressors.
