Abstract
A spiral flow connector imparts a spiral flow of air to urge parts being transmitted toward a central axis to avoid contact with the walls of the transmission passages of a pneumatic transmission apparatus. The invention is especially useful for preventing damage to fragile parts such as small resin molds, metal parts or powdered material. The spiral air flow prevents air stalling in the transmission passages.
