Abstract

The venturi device is removably mounted within and concentrically of a venturi housing of the apparatus. It has a plurality of elongate fluid passageways located between the inner and outer cylindrical surfaces thereof, and extending substantially parallel to a central axis of the device and housing. The passageways are spaced from each other about the circumference of the venturi device, have fluid inlets their adjacent closed ends, and have open ends adjacent an outlet section of the device possessing a frusto-conical surface that extends at a preselected angle relative to the central axis and that directs streams of fluid discharged from the open ends of the passageways angularly toward the central axis.
