Types of cylinders  

Pneumatic actuator that converts pressure energy of compressed gas into mechanical energy.  Cylinder has two types of reciprocating linear motion and reciprocating swing, as shown in The figure "Cylinder".  Reciprocating linear motion of the cylinder can be divided into single acting cylinder, double acting cylinder, diaphragm cylinder and impact cylinder 4.  

(1) Single acting cylinder: only one end of the piston rod, from the side of the piston to produce air pressure, air pressure to push the piston to produce thrust out, return by spring or weight.  

(2) Double-acting cylinder: alternately supply air from both sides of the piston, output force in one or two directions.  

Diaphragm cylinder: diaphragm instead of piston, only in one direction output force, with a spring reset.  It has good sealing performance but short travel.  

④ Impact cylinder: this is a new type of component.  It converts the pressure energy of the compressed gas into the kinetic energy of the piston's high-speed (10 ~ 20 m/s) movement to do work.  

Rodless cylinder: the general name of the cylinder without piston rod.  There are magnetic cylinder, cable cylinder two categories.  

Reciprocating swing cylinder is called the swing cylinder, the blade will be separated into two cavities, to the two cavities alternately, the output shaft swing motion, swing Angle is less than 280°.  In addition, there are rotary cylinder, gas-liquid damping cylinder and stepping cylinder.
