Abstract
A self-inflating tire assembly includes one or more air tube(s) connected to a tire and having a plurality of adjoining diaphragm chambers separated by a one-way valve. An air passageway extends through the air tube and the diaphragm chambers. The one-way valve allows a directional passage of air through the valve from an inlet valve side an outlet valve side. The footprint in a rotating tire sequentially collapses the diaphragm chambers to directionally pump air through the one-way valve between the diaphragm chambers and along the air passageway from an air tube inlet device to an air tube outlet device.
