Pneumatic Control Systems & EDD ¡ ¡ DDP and POE EDD: Animatronics are brought to life Gaining experience in the area of manual arts Engineering schools and labs

Where are Pneumatic Systems Used? ¡ ¡ ¡ Animatronics/Robo tics Transportation HVAC (Heating Ventilation Air Conditioning) Amusement Rides Industrial Equipment

Part I: Basic Pneumatic Parts & Equipment ¡ ¡ ¡ ¡ Piston Air Compressor Tubing Regulator Valve Solenoid Switch Power Supply

Piston ¡ ¡ Known as Air Cylinder Stores potential energy (compressed air) Converts into kinetic energy as air expands to reach atmospheric pressure Engineers prefer pneumatics since it’s cheaper, quieter, cleaner, and takes less space.

Air Compressor ¡ ¡ Using pistons and valves stores compressed air Oil and oil-less models

Tubing • Available in Difference sizes, and lengths • Used to transport compressed air from the Compressor • 1/4” and 3/8” Nylon Tubing is idea for EDD

Regulator Valve • Controls the pressure of air • Measured in PSI (Pounds Per Square Inch) – unit of pressure • 30 -60 PSI for EDD • Can be controlled from compressor or can be added to pneumatic air lines

Solenoid • Electromechanical Switch • Control air flow • Open or Closed • Uses coil and slug to control air

Switch • Electrical device • Breaks or completes electrical circuit • Powers the Pneumatic Solenoid Valve • Push Button

Power Supply • Powers the Switch to Solenoid Valve • Controls air flow • Follow Safety Guidelines
