Abstract
An injector nozzle construction for producing air-filled drops of liquid includes a dosaging nozzle element coupled at its outlet to a mixing chamber provided with an air intake opening for producing a liquid/air mixture which in turn communicates with an outlet element for discharging the mixture. A particularly great uniformity and largely fluctuation-free distribution characteristic of the drops of fluid is achieved by providing between the mixing chamber and the outlet element a homogenizing and stabilizing chamber having an inlet that is substantially greater in cross-sectional size than the outlet of the mixing chamber.
Claims19
An injector nozzle construction for producing air-filled drops of liquid comprising:
- a dosaging nozzle element having a nozzle orifice aligned coaxially with a central longitudinal axis of said nozzle construction for producing a jet of liquid in a downstream direction along said axis;
- a mixing chamber arranged immediately downstream of said dosaging nozzle element having a fluid inlet aligned coaxially with said nozzle orifice for receiving said liquid, at least one air intake opening for introducing air into said chamber to produce a liquid/air mixture, and an outlet of predetermined cross-sectional size for discharging said liquid/air mixture from said mixing chamber, said mixing chamber conically widening in a direction toward said outlet;
- an outlet element having at least one outlet orifice spaced longitudinally downstream of said mixing chamber for expelling said liquid/air mixture;
- and
- a homogenizing and stabilizing chamber between said mixing chamber and said outlet element, said homogenizing and stabilizing chamber having an inlet communicating directly with said outlet of said mixing chamber and having a cross-sectional size substantially greater than said cross-sectional size of said mixing chamber outlet.
