Pneumatic transmission element that converts the pressure energy of compressed gas into mechanical energy in pneumatic transmission.

There are two types of cylinders for reciprocating linear motion reciprocating swing. The cylinders for reciprocating linear motion can be divided into four types: single effect, double effect, diaphragm type impact cylinder.

Single-effect cylinder: There is a piston rod at only one end, the gas is supplied the side of the piston to generate air pressure.

    Double-effect cylinder: Replace the air supply both sides of the piston to output force in one two directions. Diaphragm cylinder: replace the piston with a diaphragm, output force in only one direction, reset with a tension spring. It has good sealing performance but short stroke. Impact cylinder: This is a new type of component. It converts the pressure energy of the compressed gas into the kinetic energy of the high-speed (10-20 meters / second) movement of the piston to work. The impact cylinder adds a middle cover with a spout a drain. The middle cover the piston divide the cylinder into three chambers of the gas storage cavity, the head cavity the tail cavity. It is widely used in various operations such as blanking, punching, crushing forming. The cylinder for reciprocating pendulum is called a swing cylinder. The inner cavity is divided into two by the blades, the air supply is replaced to the two chambers. The output shaft swings the swing angle is less than 280 °. In addition, there are slide cylinders, gas-liquid damping cylinders stepping cylinders.
