TIRE VALVE - MICRO AIR PUMP

An automatic micro-pump which is able to replace the depleted air in a tire without any required action from the driver of a motor vehicle. Using the kinetic energy of the rotating tire, the micro-pump maintains the tire pressure from losses due to rubber permeability or temperature changes. The mic...

More Information
Summary:An automatic micro-pump which is able to replace the depleted air in a tire without any required action from the driver of a motor vehicle. Using the kinetic energy of the rotating tire, the micro-pump maintains the tire pressure from losses due to rubber permeability or temperature changes. The micro pump has an off-balance winding wheel (26) and a primary gear set (50). The off-balance winding wheel drives the primary gear set (50), and a secondary gear set (58) connected to and driven by the primary gear set (50). A pump assembly (86) is connected to and driven by the secondary gear set (58) such that as the off-balance winding wheel rotates, the off-balance winding wheel drives the primary gear set (50), and the primary gear set (50) drives the secondary gear set (58), driving the pump and increasing the air pressure in the tire. The pump assembly (86) draws air from the atmosphere, and forces the air into the tire.
