About pneumatics

Pneumatic systems typically involve a source of compressed air being controlled by valves and causing output devices such as cylinders to operate in a controlled way.

The compressed air is typically obtained from a COMPRESSOR, which is usually driven by an electric motor or an internal combustion engine.

Air is routed through pipes to VALVES which control the routing of the compressed air. Valves may be operated by a range of ACTUATORS including levers, rollers and solenoids.

The air is then passed on to cylinders which convert the energy in the compressed air into linear motion and do useful work.

Finally, the used compressed air is released into the atmosphere as EXHAUST.
