What is the principle of automatic tire inflation?

Principle of automatic tire inflation: When the tire pressure drops to a predetermined value, the regulator will turn on the switch to suck air into the suction pipe. When the tire rolls, the air intake pipe will be crushed and air will be forced into the tire intake valve.

This automatic tire inflation intelligent system skillfully uses a sensor and several regulators to complete the inflation process without external power such as air pump or electronic equipment. Its working principle is as shown in the figure: when the tire pressure drops to a predetermined value, a regulator in the tire will open to let air enter the intake pipe; When the car starts rolling the tire, the tire deformation process will crush the intake pipe, draw air through the tire into the intake valve, and then enter the tire.
