The invention relates to a method for generating a foam from a liquid phase and a gas phase, a method for placing a foam in circulation in an installation, and a method for cleaning an installation by placing a foam in circulation. Generation of the foam is made by aspiration of an appropriate liquid phase and an appropriate gas phase to generate a foam through a porous lining. The invention also relates to a system for generating a foam and to a system for generating and placing a foam in circulation in an installation.

A mask assembly as claimed in claim 1, wherein the orifice does not change shape upon application of pressurized gas. 12. A mask assembly as claimed in claim 1, wherein first and second ends of the orifice are located proximate an opening of the mask or conduit at, respectively, the inner side of the vent assembly and the outer side of the vent assembly. 13. A mask assembly as claimed in claim 1, wherein a thickness of the vent assembly is greater than an inner diameter of the orifice. 14. A mask assembly as claimed in claim 13, wherein a ratio of the thickness of the vent assembly to an outer diameter of the orifice is about 2. 15. A mask assembly as claimed in claim 14, wherein a ratio of a length of the orifice to a thickness of the mask or conduit is about 3. 16. A mask assembly for use with a system for supplying breathable gas pressurized above atmospheric pressure to a human or animal's airways, the mask assembly comprising: a mask that is, in use, in fluid communication with a gas supply conduit; and a gas washout vent assembly including at least one gas washout orifice extending from an inner side of the vent assembly positioned, in use, adjacent the human or animal's face to an outer side positioned, in use, adjacent the atmosphere, wherein a cross-sectional area of the orifice at the inner side of the vent assembly is larger than a cross-sectional area of the orifice at the outer side of the vent assembly; and wherein the orifice includes a first substantially cylindrical portion adjacent the inner side, a second substantially cylindrical portion adjacent the outer side and a tapering portion between the first substantially cylindrical portion and the second substantially cylindrical portion. 17. A mask assembly as claimed in claim 16, wherein the second substantially cylindrical portion and the tapering portion are of approximately equal thickness in the axial direction of the orifice and are thicker than the first substantially cylindrical portion. 18. A mask assembly as claimed in claim 16, wherein the tapering portion is present independent of whether the mask is in use. 19. A mask assembly as claimed in claim 16, wherein a thickness of the vent assembly is greater than an inner diameter of the orifice. 20. A mask assembly as claimed in claim 19, wherein a ratio of the thickness of the vent assembly to an outer diameter of the orifice is about 2. 21. A mask assembly as claimed in claim 20, wherein a ratio of a length of the orifice to a thickness of the mask or conduit is about 3. 22. A mask for use with a system for supplying breathable gas pressurized above atmospheric pressure to a human or animal's airways, the mask assembly comprising: a mask that is, in use, in fluid communication with a gas supply conduit; and a gas washout vent assembly, the gas washout vent assembly including at least one gas washout orifice extending from an inner side of the vent assembly positioned, in use, adjacent the human or animal's face to an outer side positioned, in use, adjacent the atmosphere, wherein a cross-sectional area of the orifice at the inner side of the vent assembly is larger than a cross-sectional area of the orifice at the outer side of the vent assembly; wherein the vent assembly includes a plurality of said orifices therethrough and said orifices are separated from each other by at least the diameter of the orifice at the outer side of the vent assembly, and wherein the inner side of the vent assembly extends inside the mask or conduit and the outer side of the vent assembly extends outside the mask or conduit. 23. A vent assembly for washout of gas from a mask or conduit used with a system for supplying breathable gas pressurized above atmospheric pressure to a human or animal, the vent assembly including at least one gas washout orifice extending from an inner side of the vent assembly placed, in use, adjacent the human or animal's face to an outer side placed, in use, adjacent the atmosph
