Dynamic rotary inflation system

An apparatus comprising:

• a supply conduit coupled to a source of pressurized fluid;
• and
• a hub assembly comprising a rotary union and a hub, the supply conduit passing through the rotary union to the hub, the hub comprising a diaphragm, a sealing surface, a biasing mechanism, and a lead conduit, the biasing mechanism biased against the sealing surface by the biasing mechanism, the diaphragm separating the supply conduit from the lead conduit, the lead conduit coupled to an inflatable member, the biasing mechanism facilitating bi-directional fluid flow between the supply conduit and the lead conduit in response to a pressure of the pressurized fluid and a predetermined threshold pressure, wherein the supply conduit comprises a supply reservoir proximal the diaphragm, the supply reservoir having a greater cross-sectional diameter than the supply conduit and comprising a pair of outlets and a pair of fluid features, and wherein a longitudinal axis of the supply conduit is positioned between the pair of outlets and the pair of fluid features.
