Zusammenfassung:A nozzle assembly comprises a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; and 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 directs fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold. The assembly comprises a cylindrical poppet slidably disposed within the central bore, a guide between the nozzle body and the poppet, and a biasing member within the cartridge case between the front portion of the nozzle body and the poppet urging the poppet away from the front portion of the cartridge case.
