Patent ID: 7776157

Claim:
A cleaning device, comprising: an enclosure ( 1 ), a cover ( 15 ), allowing it to be opened in order to place an object ( 30 ) to be cleaned within the enclosure, and a supply of cleaning fluid ( 4 ), wherein the enclosure ( 1 ) comprises: a piston ( 8 ) that can move with the aid of a motor ( 9 ), and wherein the enclosure ( 1 ) comprises a geometry ( 11 , 12 , 13 ) allowing a contact with an external fluid reservoir when the piston occupies a certain position within the enclosure ( 1 ) in order to generate a sudden release of pressure, wherein the device comprises an outlet valve remaining closed when the piston increases the volume of the enclosure so as to cause the pressure reduction within the enclosure ( 1 ), wherein when the motor ( 9 ) pushes the piston ( 8 ) within the enclosure ( 1 ) in the direction of reducing the volume of the enclosure ( 1 ), the pressure of the enclosure ( 1 ) remains constant under the effect of an open outlet valve ( 7 ), wherein when the motor ( 9 ) pulls the piston in the opposite direction so as to increase the volume of the enclosure ( 1 ), with the valve ( 7 ) being closed, the pressure reduces within the enclosure ( 1 ), and wherein there is a sudden release of pressure within the enclosure ( 1 ) by placing the enclosure ( 1 ) in contact with the external fluid when the piston ( 8 ) reaches the geometry ( 11 ; 12 ; 13 ) of the enclosure ( 1 ).
