What Is a Reciprocating Air Compressor?
Reciprocating air compressors, also known as piston air compressors, operate via positive displacement. In a typical piston compressor configuration, consisting of two stainless steel valve discs and a valve system, the piston moves downward and pulls air into a cylinder. The larger of the two discs flexes, allowing the air to pass through. The piston then moves upward, causing the larger disc to flex and form a seal against the valve seat. This process forces compressed air through a hole in the valve seat.
