Reciprocating compressors are mechanical devices that increase the pressure of gases by reducing their volume. They operate using a piston that moves back and forth within a cylinder, drawing in gas on one stroke and compressing it on the next. This type of compressor is commonly used in various applications, including refrigeration, air conditioning, and industrial processes. These compressors can be powered by electric motors or internal combustion engines. They are known for their efficiency and ability to handle high-pressure applications. Common types of reciprocating compressors include single-stage and multi-stage compressors, which differ in the number of compression stages they utilize.
