Definitions

  • the invention relates to a device for the evacuation of gaseous fluid, in particular of exhaust gases or smoke.
  • Such devices are for example of the type comprising a lower element, upper element, spacers to rigidly hold the two coaxial elements spaced from each other so as to define between them a passage, and a conduit passing through the lower element and opening into the passage.
  • the lower and upper elements are limited by conical or frustoconical side walls, so that said passage has, in axial section, a general shape of venturi or convergent / divergent, along a direction radial orthogonal to the general axis of the device.
