Ejector assembly

Claim 1

An ejector assembly for intermingling a liquid with a gas to produce a solution to be fed to an application point, said assembly comprising: A. an ejector body having an elongated tubular throat extending axially therefrom; B. a nozzle disposed in a cylindrical cavity within said body, the mouth of said nozzle being adjacent the inlet of said throat to define an interaction zone therebetween, the space in said cavity behind said nozzle defining a liquid input zone; C. means to feed liquid under pressure into said input zone whereby liquid at high velocity is emitted from the mouth of said nozzle into the interaction zone to create a vacuum, said liquid feed means being at right angles to the longitudinal flow axis of said ejector body to define an elbow rendering the liquid input to said nozzle turbulent; D. means communicating with said interaction zone and coupled to a gas supply to cause gas to be drawn into said interaction zone by said vacuum to intermingle with the liquid therein and to produce said solution which is discharged through said throat; and E. a plug coaxially-disposed within said nozzle and said input zone to define an annular flow path having flow disturbances therein imparting a high degree of turbulence to the liquid issuing from the nozzle, thereby enhancing its interaction with said gas, the internal bore of said nozzle being contoured to cooperate with a flange of enlarged diameter formed on said plug to create alternate restrictions and expansions in said flow path through said nozzle.
