Exploring Compressed AirExploring Compressed Air

When you push on the pump handle,

you are compressing air and giving it

energy.

The valve controls the direction of the

compressed air.

The compressed air is sent to the cylinder to make the piston and the piston rod

move.

Let’s look at the parts of a pneumatic system.
