Patent ID: 8448880

Claim:
A nozzle system for generating a high-pressure abrasive waterjet, comprising: a nozzle main body consisting of a single piece of material, the single piece of material comprising a fluid flow conduit and a media flow conduit extending therethrough, the fluid flow conduit extending through the single piece of material of the nozzle main body from a high-pressure water inlet toward an outlet through which a high-pressure waterjet exits the nozzle system, the fluid flow conduit having an upstream section and a downstream section, the upstream section comprising a flow redirector configured and dimensioned to receive high-pressure water flow traveling in a first direction and to output the high-pressure water flow in a second direction toward the downstream section of the fluid flow conduit, the first direction being substantially different than the second direction, the media flow conduit extending through the single piece of material between a media inlet and the downstream section of the fluid flow conduit such that abrasive media passing through the media flow conduit is mixed with the high-pressure waterjet; a nozzle orifice interposed between the upstream and downstream sections of the fluid flow conduit within the single piece of material of the nozzle main body such that high-pressure water in the upstream section passes through an aperture of the nozzle orifice to generate the high-pressure waterjet; and a delivery conduit positioned downstream of the nozzle orifice within the downstream section of the fluid flow conduit of the nozzle main body, the delivery conduit including the outlet through which the high-pressure waterjet exits the nozzle system.
