A reciprocating compressor is a positive displacement device that compresses gas by using a piston driven by a crankshaft. The piston moves back and forth in a cylinder, drawing in gas during the intake stroke and compressing it during the compression stroke. These compressors are capable of achieving high pressures and are suitable for a variety of gases. They are widely used in applications such as refrigeration, air conditioning, and industrial processes. Known for their durability and reliability, reciprocating compressors can handle intermittent and continuous operation, making them a versatile choice for many settings.
