PCT No. PCT/FR96/00170 Sec. 371 Date Aug. 1, 1997 Sec. 102(e) Date Aug. 1, 1997 PCT Filed Feb. 1, 1996 PCT Pub. No. WO96/24011 PCT Pub. Date Aug. 8, 1996The present invention relates to a method for confining an atmosphere (B) in a space (4) communicating with its surroundings via at least one opening. A gas curtain (1+2) comprising a low-velocity jet (2) and a high-velocity jet (1) is generated at said opening. Characteristically, a fraction of the flow in said low-velocity jet (2) is injected into the confined atmosphere (B) and adds to the induced flowrate of said low-velocity jet (2), the size of said fraction being variable depending on the pressure within said space (4). The present invention also relates to a device for carrying out said method. |
