  • Publication number: 20130160918
    Abstract: An air maintenance tire and connector system includes a tire carcass having an elongate integral air passageway contained within a flexible tire component of the tire carcass between an air inlet and an air outlet cavity and a connector assembly inserted within an outlet one of the cavities. The connector assembly includes a hollow right angled elbow-shaped body fitting within the outlet cavity. The elbow-shaped body's second housing segment has an axial length sufficient to project axially inward from the first housing segment through a tire wall thickness to a tire central cavity. A valve device attaches to a remote end of the second housing segment within the tire cavity, the valve device operative to regulate air flow between the elbow-shaped body central chamber and the tire cavity.
