ABSTRACT:
A hydrotherapy fitting assembly is provided, featuring: an axial nozzle socket and a nozzle therein, receiving an axial flow of water and air, and projecting them in admixture from the housing as a jet stream; the nozzle comprising two pieces threadably and fixedly linked together for pivoting and rotating movement together in the socket; a cylindrical housing piece defining a central chamber; a cylindrical plug valve piece having an axial water inlet at one end an axial water outlet at the other end, threadably mounted in the control chamber, and movable axially on the threads in the central chamber of the cylindrical housing between limiting positions extending across and closing off the side water inlets, and fully exposing and opening the side water inlets, with intermediate positions partially exposing and opening the side water inlets; and leaving the air inlet exposed and open in both limiting positions of the valve; and constraining water flow therethrough first in an axial direction, then in a direction at an angle thereto, and then again an axial direction, and thereby in an S-curved path; the cylindrical plug valve piece having a nozzle portion defining the axial water jet outlet of the plug valve piece and projecting mixed air and water from the nozzle mixing chamber.
