AbstractA showerhead of the type including an inlet end, an outlet end, and a bore defining a passage between the two. Two discs are disposed in the passage, in face-to-face engagement with each other and mounted for relative rotation about a central axis. A plurality of orifices, arranged with their centers spaced at regular intervals around a circle of predetermined diameter, extend through each disc. Each orifice of the downstream disc defines a small port at the downstream face and a large port at the upstream face of the disc. Each orifice through the upstream disc defines at its downstream face a port that communicates with but is smaller than a respective port at upstream face of the downstream disc.
