SELF-INFLATING TIRE AIR REGULATOR

摘要

An air regulator that when implemented inside a pneumatic tire having an internal reversible peristaltic pump prevents air from entering the peristaltic pump when a tire air pressure in a pressurizable cavity of the tire is greater than a selectable set point pressure. The teachings further include opening an air passage between an atmosphere external to the tire and an intake of the peristaltic pump when the tire air pressure in the pressurizable cavity of the tire is less than or equal to the selectable set point pressure.
