Patent abstract
A suspension system can include an air spring, an air reservoir external to the air spring, and a flow control device which variably restricts flow of air between the air spring and the air reservoir. Flow between the air spring and the air reservoir may be permitted in response to compliance of the suspension system, and the air spring can have an internal air volume at least 2½ times as great may permit flow between the air spring and the air reservoir in response to a predetermined pressure differential level across the flow control device. Multiple air reservoirs can be internal to an axle, or other suspension system or vehicle component, and can be isolated from each other.
