Abstract
To assure inflation of a tire 2 during its rotation, a hose 3 is placed on he inside periphery of rim 1. A pressure roller 5, solid with the wheel carrier and therefore non-rotatable, causes a local reduction in the section of hose 3. During rotation of tire 2, air is forced from an orifice 31 forming an air intake, to an inside volume 20 of tire 2, via a check valve 4. To provide deflation, a roller rests on a pusher which controls the opening of valve 4.
