Pneumatics is a branch of science connected with usage of the compressed air as the energy carrier and as the information about the working medium. It is currently one of the most popular techniques in the industry. It is used in drives and supply control machinery, equipment and processes. Use of the compressed air is associated most often with these simple concepts:

• pneumatic drive
• pneumatic control

In the pneumatics drives compressed air is used as the energy carrier, while in the pneumatic control systems is carries the information.
Functions of the compressed air in the pneumatic controlled systems:

• It carries the energy and control signals,
• It discharges the heat,
• In some systems it lubricates the moving sufrace,
• It reduces the usage of spare parts of the pneumatic system.

A block diagram of a basic pneumatic system:

1. A compressor is the first element of the pneumatic system, which is responsible for transferring atmospheric air into the energetic medium.
2. Air preparation unit is the second element of the pneumatic system, and it is responsible for the compressed air treatment
3. Control elements are the third part of the pneumatic system
4. Cylinders are the fourth and the last element of the pneumatic system, and their task is to transform the compressed air energy into to mechanical energy

This block diagram above is applicable to most practical applications of pneumatic systems.
