① Single-acting cylinder: There is a piston rod at only one end. The air is supplied from one side of the piston to generate air pressure. The air pressure pushes the piston to generate thrust and extend, and returns by spring or self-weight.
② Double-acting cylinder: Air is supplied alternately from both sides of the piston, and force is output in one or two directions.
③ Diaphragm cylinder: The diaphragm is used instead of the piston, and force is output in only one direction, and reset by spring. It has good sealing performance, but short stroke.
④ Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of the high-speed (10-20 m/s) movement of the piston to do work.
⑤ Rodless Cylinder: A general term for cylinders without piston rods. There are two major categories: magnetic cylinders and cable cylinders.
A cylinder that does reciprocating swing is called a swing cylinder. The inner cavity is divided into two by a blade, and air is supplied alternately to the two cavities. The output shaft swings, and the swing angle is less than 280°. In addition, there are rotary cylinders, gas-liquid damping cylinders, and stepping cylinders.
