Abstract
A liquified gas dry-cleaning system including a storage tank containing a liquified gas derived from a liquifiable gas, a pressure vessel for containing a liquid bath derived from the liquifiable gas, and a circulating system for transporting the liquified gas between the storage tank and the pressurized vessel. The pressurized vessel includes a compressor mounted in a wall structure of the vessel for use in evacuating a gaseous form of the liquifiable gas released from the liquid bath during a cleaning cycle. Positioning of the compressor in this manner allows heat generated during each compression stroke of the compressor to be directed to the interior of pressure vessel to minimize the effects of a temperature decrease incident to the gaseous evacuation.
