Abstract
An air suspension system with an air drier that adjusts vehicle height quickly especially when lowering the height. This system also efficiently maintains the desiccating capacity of the air drier. In lowering the vehicle, all the air discharged from an air actuator is compressed by a compressor and supplied to an accumulator, thus reducing the load on the compressor. When vehicle height is not adjusted and the pressure in the accumulator exceeds a preset value, the air is released from the accumulator into the atmosphere through a throttle valve and the air drier to restore the capacity of the desiccating material in the air drier.
