Abstract
A pressure vessel for receiving and storing pressurized fluid in a pressurized dense phase liquid dry cleaning apparatus is provided. The dry cleaning apparatus generally includes a cleaning vessel within which garments or the like are cleaned and a solvent recovery device which takes the contaminated cleaning fluid from the cleaning vessel and separates out the contaminants. The pressure vessel comprises a plurality of interconnected hollow structures and as such is substantially self-supporting and occupies less space within dry cleaning apparatus. The pressure vessel can also serve as the support structure for the other components of the dry cleaning system to provide a further cost and space savings.
