Pneumatic Systems Are Comprised of a Few Major Parts

Pneumatic systems are comprised of a few major parts. First, there's the compressor. The compressor is a pump that compresses air, raises it to a higher pressure, and then delivers it into the actual pneumatic system. This process can also be used to generate a force that pulls (a vacuum) instead of a force that pushes. Next, there is the check valve and the directional valve. A check valve is a one-way valve that is used to grant the pressurized air access to the pneumatic system while at the same time preventing backflow. The directional valve actively controls the direction of the airflow to its correct source. You might ask, "What happens if too much air is permitted into the system? " For that there is the accumulator, which stores compressed air to prevent potentially dangerous surges in pressure while also ensuring efficient operation. Finally, there's the actuator. Pneumatic actuators convert the stored compressed air into actual mechanical motion. Typical pneumatic actuators are comprised of a piston, a cylinder, and a configuration of valves and ports. In pneumatic systems, the motion created by the actuator is usually rotary or linear. Source:lidaqd.com
