ABSTRACT:
A whirlpool jet assembly adapted to be mounted in an opening in the wall of a water tub for discharging the water stream into the tub. The jet assembly includes a housing defining a socket having an air inlet and a water inlet and a ball fitting pivotably supported within the socket having openings positionable in alignment with the air and water inlets in the socket. A nozzle assembly supported on the ball fitting is of a unitary one-piece construction forming a Venturi nozzle, mixing chamber and directional nozzle in an integral structure. The nozzle assembly is rotatably supported on the ball fitting with the ball fitting and nozzle assembly having shaped openings through which water from the water inlet flows into the Venturi jet nozzle. Rotation of the nozzle assembly with respect to the ball fitting changes the combined shape of the shaped openings to alter the pressure of water flowing through the jet assembly.
