Abstract:
A device for difficult intervention in a closed enclosure, having an enclosure connected to the closed enclosure via a duct, a piston that can be moved by a motor, a geometry allowing a contact with the outside air when the piston occupies a certain position within the enclosure in order to generate a sudden release of pressure, and an outlet valve remaining closed when the piston increases the volume of the enclosure so as to cause the pressure reduction within the enclosures.
