Abstract
A high-pressure liquid spray nozzle having an elongate nozzle body having a longitudinally extending liquid flow passage, which in the illustrated embodiment, is defined in part by a plastic liquid throttling and stabilizing insert. The insert has a liquid flow passage which includes an upstream entry section, a smaller diameter downstream approach section, and an inwardly converging throat section between the upstream and downstream sections. The upstream passageway section has a scalloped cross-sectional configuration which define a plurality of longitudinally extending flutes effective for stabilizing and minimizing turbulence in the high pressure liquid flow stream directed through the nozzle such that a more concentrated, solid liquid flow stream is discharged from the nozzle with increased velocity and surface impact force for enhanced cleaning.
