<p>A self-inflating tire assembly comprising a tire (12) having a tire cavity (40), first and second sidewalls (15) extending respectively from first and second tire bead regions to a tire tread region and an air passageway (43) having an inlet end and an outlet end is disclosed. The air passageway is composed of or established by a flexible material operative to open and close when the tire rotates. The inlet end is connected to an outlet port of a regulator device (300) and the outlet end is in fluid communication with the tire cavity (40). The regulator device (300) comprises a regulator body having an interior chamber (320). A pressure membrane (550) is mounted in the interior chamber and positioned to open and close the outlet port mounted in the interior chamber, wherein the pressure membrane is in fluid communication with the tire cavity (40). The body of the regulator device (300) is connected to a first flexible duct (400) having an internal passageway, wherein the first flexible duct has a first end connected to an inlet filter assembly (450), wherein the inlet filter assembly (450) is in fluid communication with outside air supply, and wherein a second end of the first flexible duct is connected to an opening of the interior chamber of the regulator device (300).</p> |
