Title
(EN) SELF-INFLATING TIRE
(FR) PNEUMATIQUE AUTO-GONFLABLE
Abstract
(EN)
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.
(FR)
L'invention concerne une chambre à air auto-gonflable équipée d'un mécanisme de pompage. La chambre à air auto-gonflable utilise une bande non élastique qui empêche la chambre de se dilater entièrement dans la cavité pneumatique-jante en créant ainsi une zone de basse pression. Le mécanisme de pompage est placé dans la zone de basse pression et il se comprime lorsqu'une charge est appliquée à la section de roue, en refoulant ainsi de l'air dans la chambre à air. Lorsque la roue tourne, la charge est supprimée et le mécanisme de pompage revient à sa forme originale, en aspirant de l'air pour le cycle de pompage suivant.
