Abstract
A nozzle assembly includes a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; a switching valve assembly disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and direct fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold; and a flow insert configured to replace the switching valve assembly for directing flow through all of the ports when switching functionality is not needed. This flow insert may be made of a low pressure material such as a polymer.
