Abstract
A fluidic nozzle of the scanner type has its outlet spray pattern skewed from its chamber axis (A) by an amount determined by the asymmetry of its outlet orifice (23, 33) about that axis. A spray assembly (70, 90) of such nozzles, such as a showerhead, can be designed using nozzles with selected pattern skew angles to achieve desired spray coverage. Indexing tabs (97) and slots (96) are used to angularly position the nozzles in the showerhead. A portion of each nozzle may be formed with the showerhead faceplate (71) as an integral piece.
