Air Suspension System Operation

Air springs are basically installed on the rear and front axles. The incoming air is first passed through the filter, where the dust is filtered and then the air is passed into the compressor. Here, the air is compressed and its pressure increased from the pressure up to about 250 MPa. Then this pressure is sustained in the accumulator tank. This accumulator has a safety relief valve, which acts as a safety device by opening when the air pressure goes above 250 MPa. The air is then conveyed to elevate control valve and then through leveling valves up to the air springs.
