Abstract
A nozzle assembly including a nozzle body having an inlet at a first end and an outlet at a second end. A first fluid passageway is defined within the nozzle body for first fluids passing between the inlet and outlet. Second and third fluid passageways for respective second and third fluids are also defined within said nozzle body. A discharge mixing unit is provided at the second end and is in fluid communication with the first, second and third fluid passageways for mixing the first, second and third fluids to produce a discharge solution.
The discharge mixing unit includes one or more mixing chambers provided on the interior surface of the second end of the nozzle body.
The mixing chambers are defined between a plurality of inwardly extending blades from the interior surface of the second end. The second end of the nozzle body has an adjustably extending pattern selection sleeve.
The third passageway includes a variable fluid flow control device which is operable for varying the expansion ratios of the discharge solution.
