1. Manual Control Systems: Pneumatics “A Slice of Mechanical Engineering” Mr. J. Butler ● Department of Technology & Engineering ● John Jay High School ● Wappingers Central School District

2. 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

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

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

5. 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.

6. Air Compressor  Using pistons and valves stores compressed air  Oil and oil-less models

7. 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

8. 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

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

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

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

12. Observations  What makes the grave jumper work? Moving Parts Sounds Range of Motion Speed Pressure

13. Questions and Further Knowledge  Mechanical Supply Companies Granger DigiKey  Mechanical or Electrical Engineer  Web Resources  Library
