Abstract
This invention is directed to an internally tapered transition section to channel water or other cutting liquid from a supply pipe to a nozzle body having a plurality of orifices for liquid jet cutting. The transition section described herein is interposed between a supply pipe and a nozzle body and provides a smooth contour matching between the end of a supply pipe and a nozzle entrance whereby the water is conducted to the nozzle exits with a minimum generation of disturbance, mixing, and energy loss.
