<p>The invention relates to a cleaning device comprising a chamber (1), a lid (15) for opening the same to place an object (30), for cleaning, within the chamber and a cleaning fluid supply. The housing contains a piston (8), driven by a motor (9), with a layout permitting contact with an external fluid reservoir when said piston (8) is in a certain position within the chamber (1) such as to generate a sudden release of pressure. The device comprises an outlet valve which remains closed when the piston increases the volume of the chamber such as to generate the drop in pressure within the chamber. ® KIPO & WIPO 2007</p> |
