Title (EN) CLEANING PARTS
(FR) NETTOYAGE DE PIÈCES
Abstract:
(EN) In an example implementation, a method of cleaning parts includes placing the parts into a variable compression chamber, filling the chamber with a liquid, and forcing pressurized gas to dissolve into the liquid to form a gas-liquid solution. The method includes cycling the pressure within the chamber around a gas solubility pressure level to repeatedly bring gas molecules out of the solution as gas bubbles, and force the gas molecules to dissolve back into the solution.
(FR) Selon un exemple de mise en oeuvre, un procédé de nettoyage de pièces consiste à placer les pièces dans une chambre à taux de compression variable, à remplir la chambre avec un liquide, et à forcer le gaz sous pression à se dissoudre dans le liquide pour former une solution gaz-liquide. Le procédé consiste : à mettre en pression répétée le gaz à l'intérieur de la chambre, autour d'un niveau de pression de solubilité du gaz, pour extraire de manière répétée les molécules de gaz de la solution sous forme de bulles de gaz; et à forcer les molécules de gaz à retourner se dissoudre dans la solution.
