Questions this course answers

What does the piston change?

Moving the piston changes chamber volume and therefore pressure.

Why are check valves needed?

One-way valves prevent air from returning during the next stroke.

Why does pumping get harder at higher pressure?

A larger pressure difference requires more force.

What does atmospheric pressure do on intake?

Outside pressure drives air through the open inlet.

What must the pump head provide?

A sealed connection lets pressure push air into the tire.
