A reciprocating compressor is a type of positive displacement compressor that uses a piston to compress gas. The piston moves back and forth within a cylinder, creating a vacuum that draws in gas and then compresses it as the piston moves forward. This design is commonly used in various applications, including refrigeration and air conditioning systems. These compressors are known for their efficiency and ability to handle high pressures. They can compress a wide range of gases, making them versatile for industrial and commercial use. Key components include the cylinder, piston, and valves, which work together to facilitate the compression process.
