The principle of this kind of products is motor operation. When pumping air, the atmospheric pressure pushes the valve of the communication device open, and the gas enters the air pump. When the tire is inflated, the valve is closed by the air pressure in the air pump, and the gas enters the tire. Some people think that cars, balls and rubber boats are inflated by atmospheric pressure.
