Abstract
A bellows system includes a first bellows segment having a first end and a second end, the first bellows segment configured to elastically compress and expand. A first plate is coupled to the second end of the first bellows segment and a first sleeve is concentric with the first bellows segment, the first bellows segment disposed within the first sleeve. A second bellows segment has a third end and a fourth end. The second bellows segment is configured to elastically compress and expand, and the third end of the second bellows segment is coupled to the first plate. A second sleeve is coupled to the first plate. The second sleeve is concentric with the second bellows segment and the first sleeve, and the second bellows segment is disposed within the second sleeve. The second sleeve is configured to travel within the first sleeve.
