Pneumatics machine is one kind reduces aeriform volume, add aeriform pressure and the mechanical equipment that transport gas, be energy resources of a kind of power consume a product.

Pneumatics machine can be divided by working principle for cubage type and speed type. Cubage type is divided again for type of piston, screw and blade type 3 kinds; Speed can divide sort type for centrifugal type and axis two kinds.
The working principle of piston pneumatics machine and actor defect:
Piston pneumatics machine is to pass air cylinder, valve and piston what to the constant change of the working cubage that reciprocate place forms will finish is in inside air cylinder, can divide for inspiratory, reduce the process with exhaust. Piston pneumatics mechanic makes a principle: Reduce a process: Piston by fall to move up, inspiratory shut with exhaust valve, gas is compressed inside the air cylinder that close. Reduce as air cylinder cubage, pressure and temperature are elevatory, till the aeriform pressure inside air cylinder and platoon atmospheric pressure force is equal. Exhaust process: The piston continues to move up, make the aeriform pressure inside air cylinder is more than a baric force, exhaust valve is opened, the gas inside air cylinder is in of the piston drive next emiting into vent-pipe, till the piston shift arrives. Bit taller. Right now, because the bedspring force of exhaust valve is mixed,the gravity of itself of board of a powerful person is made with, exhaust valve is shut, exhaust ends. Actor defect: Piston pneumatics machine is low-cost, defend simple petty gain, but easy bad, noise is bigger.
