Pneumatic Cylinders

The pneumatic cylinders contained a piston that would move according to the flow of air. Early cylinders had a single working chamber that moved the piston up or down depending on whether air was drawn in or sucked out through a single port. Later cylinders contained 2 working chambers: The piston would move depending on whether the top or bottom chamber was filled with air.
