ABSTRACT:
Apparatus are provided for a damping system. The system includes a housing having an inner surface defining a passage therethrough, a first bellows disposed within the passage, the first bellows having an outer surface and spaced apart from the housing inner surface to define a first chamber having a volume, a second bellows disposed within the passage, the second bellows having an outer surface and spaced apart from the housing inner surface to define a second chamber having a volume, a restrictive flow passage in fluid communication with the first and second chambers, fluid disposed within the first chamber, the second chamber, and the restrictive flow passage, and a piston coupled to the second bellows and disposed at least partially within the restrictive flow passage, the piston configured to selectively receive a force to thereby move the piston through the housing passage.
