ABSTRACT:
An improved and tunable ultrahigh-pressure nozzle for use in generating ultrahigh-pressure fluid jets is shown and described. In a preferred embodiment, a nozzle body is provided with a first conical bore that extends from an entrance orifice to an exit orifice, the bore transitioning into a second conical bore that is formed in a seal. The seal is formed to capture a nozzle orifice and position it in the nozzle body adjacent the exit orifice. By selecting the geometry of the nozzle, namely the diameter of the entrance orifice, and an included angle of the first and second conical bores, it is possible to optimize performance of a fluid jet generated by the nozzle for a selected task and operating parameters.
