Beschreibung
Zusammenfassung:	The invention relates to a cleaning apparatus which uses as operative fluid liquid and/or supercritical carbon dioxide (CO2) or other dense-phase fluids such as ammonia or hydrocarbons. The apparatus may have various applications including the cleaning of garments and the degreasing of electronic or mechanical components; the apparatus comprises a cleaning chamber (1), basically formed by a pressurised container, and an installation for supplying the CO2 which includes a storage tank (30) and a distiller (31). Advantageously, in order to start a cleaning cycle, the chamber (1) is pressurised with gaseous CO2 taken from the tank and/or from the distiller which are then excluded from the path of the liquid CO2 used for the actual cleaning. The invention also comprises a special cleaning chamber (1) having a lid and a cylindrical jacket, that are provided with respective mating edges between which operates an improved seal suitable for preventing leakage of supercritical fluids.
