Abstract

A spring disk with a concentric through bore and a concentric counter bore of specific depth used to hold an orifice against a lapped surface of a nozzle cap in a waterjet assembly. Dimensions are chosen to provide adequate restraint without the need to force the orifice onto the spring disk. When orifice, spring disk and the retaining cap are assembled and the cap is tightened on the inlet nozzle, the spring disk is forced to the cap surface and the orifice becomes securely held and centrally aligned within the assembly.
