ABSTRACT:
An Automatic Tire Pressure Control System (APS) compensates for fluctuations in the air pressure and temperature of vehicle tires and automatically adjusts the tire pressure. This provides the vehicle operator with a convenient means to automatically regulate the pressure of a vehicles' tires for optimum safety and performance. The system provides nonwearing ferrofluid seals for zero air leakage and a special axle sleeve with multiple air channels for reduced inflation time and an air flow path that is isolated from lubricants, an air compressor powered by a vehicle engine and a microprocessor controlled distributor which distributes air to each tire, depending on a tire pressure and temperature sensor signalling air and temperature requirements. A tire venting system is also provided.
