Intersecting jet - waterjet nozzle

Abstract

A liquid fan jet nozzle having a housing with a central passage having an inlet and an outlet. A subnozzle is arranged in the central passage and has two round orifices arranged along converging axes so that round liquid jets exiting the round orifices collide at a distance from the orifices and form a fan-shaped jet.

1 . A liquid fan jet nozzle, comprising: 
 a housing having a central passage with an inlet and an outlet; and    a subnozzle arranged in the central passage, the subnozzle having two round orifices arranged along converging axes so that round liquid jets exiting the round orifices collide at a distance from the orifices and form a fan-shaped jet.    
     
     
         2 . The nozzle according to  claim 1 , wherein the round orifices are sapphire orifices.  
     
     
         3 . The nozzle according to  claim 1 , wherein the round orifices of the subnozzle are aligned so that a horizontal component of a first of the orifices cancels a horizontal component of a second of the orifices.  
     
     
         4 . The nozzle according to  claim 3 , wherein an angle that encompasses the fan jet is a function of an angle between the converging axes of the round orifices in the subnozzle.
