Air suspension is a type of vehicle suspension powered by a Gas Compressor
A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compression of a gas naturally increases its temperature.
Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible, so the main action of a pump is to move the liquid elsewhere.
Applications for Gas Compressors
Gas compressors are used in various applications where either higher pressures or lower volumes of gas are needed:
in pressurised aircraft to provide a breathable atmosphere of higher than ambient pressure
in jet engines to provide the great mass of operating fluid and, at high altitudes, a high enough concentration of oxygen for combustion of the air and fuel mixture. The power to turn the compressor comes from the jet's own turbines.
in many various industrial, manufacturing and building processes to power all types of pneumatic tools.
in medicine and manufacturing to store purified or manufactured gases in a small volume
as a medium for transferring energy, such as to power pneumatic equipment
in refrigeration and air conditioner equipment to move heat from one place to another in refrigerant cycles: see heat pump.
in pipeline transport of domestic gas to move the gas from the production site to the consumer
in SCUBA diving, hyperbaric oxygen therapy and other life support devices to store breathing gas in a small volume such as in diving cylinders
in submarines to store gas for later use as buoyancy
in turbochargers and superchargers to increase the performance of internal combustion engines by concentrating oxygen
providing compressed air for filling pneumatic tires
in a Biogas powerplant to raise the gas pressure for the gas turbines
in rail and heavy road transport to provide compressed air for operation of rail vehicle brakes or road vehicle brakes and various other systems (doors, windscreen wipers, engine/gearbox control etc).

Vehicle Suspension
Vehicle Suspension
Air suspension is a type of vehicle suspension:
Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels. Suspension systems serve a dual purpose – contributing to the car's handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps, and vibrations. These goals are generally at odds, so the tuning of suspensions involves finding the right compromise. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different.
Suspension Types
Suspension systems can be broadly classified into two subgroups - dependent and independent. These terms refer to the ability of opposite wheels to move independently of each other.
A dependent suspension normally has a live axle (a simple beam or 'cart' axle) that holds wheels parallel to each other and perpendicular to the axle. When the camber of one wheel changes, the camber of the opposite wheel changes in the same way.
An independent suspension allows wheels to rise and fall on their own without affecting the opposite wheel. Suspensions with other devices, such as anti-roll bars that link the wheels in some way are still classed as independent.
A third type is a semi-dependent suspension. In this case, jointed axles are used, on drive wheels, but the wheels are connected with a solid member, most often a deDion axle. This differs from "dependent" mainly in unsprung weight.
Interconnected suspensions (mechanically interconnected, such as anti-roll bars; and hydraulically or pneumatically interconnected, e.g., SAE 2005-01-3593, SAE 2003-01-0312) have also been used to achieve a better compromise among vertical, roll and pitch properties.
