Abstract
An absorber for use in a fluid delivery system is disclosed which includes a housing defining an interior chamber, a connective fitting extending from the housing in fluid communication with the interior chamber for connecting the housing to the fluid delivery system, and at least one gas-filled bladder or cell disposed within the interior chamber of the housing to accommodate changes in fluid characteristics, such as, for example, pressure and volume, within the fluid delivery system, the gas-filled bladder or cell having a predetermined pre-charge pressure and a multi-layered flexible polymeric shell including a plurality of successive relatively thin polymeric shell layers to inhibit the formation of leak paths through the shell in the event that a single shell layer fails.
