Nozzle for generating turbulence, comprises funnel and perforated plate containing slanting holes

摘要

The nozzle comprises a funnel (4) and a perforated plate (6-21) containing at least three holes or hole formations slanting at the same angle and evenly distributed across the plate. A cone or hyperbolic-shaped funnel is screwed onto a head piece (1) so that the perforated plate is held in a central position between the funnel and head piece. The holes slant at an angle of 85 degrees or less.
