Reciprocating Compressor A Reciprocating Compressor is a type of positive displacement compressor that uses a piston-cylinder arrangement to compress gases. As the piston moves downward, it draws gas into the cylinder through an intake valve. When the piston moves upward, the gas is compressed and discharged through an outlet valve at a higher pressure. This cyclic motion allows the compressor to deliver high-pressure gas efficiently. Reciprocating compressors are widely used in industries such
