Abstract
A dry cleaning system arranged for washing articles employing a cleaning solution. The dry cleaning system includes a wash tank (2) for washing an article to be washed with a cleaning solution. The wash tank (2) is arranged for washing the article at an increased pressure compared to atmospheric pressure. The dry cleaning system includes a fluid displacement device (1), such as a pump, connected to the wash tank (2) and is arranged for transferring the cleaning solution through the dry cleaning system in a first operational mode. The fluid displacement device is arranged to reduce the pressure in the wash tank towards atmospheric pressure in a second operational mode.
