  "textContent": "An air maintenance system is disclosed comprising an operationally rotating inner ring (80) secured to a vehicle wheel (11), a stationary outer ring (90) maintaining a constant angular position, an eccentric mass (50) secured to the stationary outer ring (90), an occlusion roller (70) located proximate to the eccentric mass (50), and a flexible tube (40) defining a pump cavity. The air maintenance system (10) is configured for pumping a fluid from the ambient environment into a cavity of a pneumatic tire (12) by applying an occluding force against the flexible tube (40) periodically occluding portions of the pump cavity.",
