Abstract:
A spray nozzle comprising:a housing formed with an inlet adapted to be connected to a source of pressurized liquid, an outwardly open outlet spaced from the inlet, a turbulence chamber opening into the outlet, a distributing chamber opening into the inlet, and a throughflow passage extending from adjacent the inlet to adjacent the outlet, whereby liquid from the inlet flows as a primary stream from the inlet through the throughflow passage to adjacent the out-let; and means including a pair of valve bodies in the housing between the distributing chamber and the turbulence chamber for forming respective secondary streams of variable intensity directed tangentially into the turbulence chamber and for combining the secondary streams in the turbulence chamber with the primary stream to project from the outlet a spray cone having a droplet size dependent on the intensities of the secondary streams.
