SELF-INFLATING TIRE

摘要

A self-inflating inner tube with a pumping mechanism is provided. The self-inflating inner tube employs a non-elastic band that constrains the tube from expanding completely within the tire-rim cavity thereby creating a low pressure zone. The pumping mechanism is placed in the low pressure zone and compresses as load is applied to the section of wheel thereby pushing air into the inner tube. As the wheel rotates the load is removed and the pumping mechanism returns to its original shape drawing in air for the next pumping cycle.
