The power output device of a pneumatic system is known as the what?

• A. Actuator
• B. Regulator
• C. Valve
• D. Filter

Answer: (A)

The device that outputs power in a pneumatic system is the actuator, because it converts compressed air energy into mechanical motion and force. An actuator can be a piston cylinder that provides linear motion (extending and retracting to move a load) or a pneumatic motor that delivers rotary motion. The other components serve supporting roles: a regulator maintains the desired pressure, a valve controls when and where air flows, and a filter cleans the air. Only the actuator directly converts the stored pneumatic energy into useful work for the system.
