ABSTRACT:
A hydro-air jet assembly wherein a ball-shaped element has a first passageway therethrough communicating with an air supply and a second passage therethrough communicating with a water supply which is rotatably mounted in a housing and has a venturi nozzle secured to the ball to corotate therewith but which is adjustable in an axial direction with respect to the ball member providing constant water and air flow rates through the ball and nozzle assembly regardless of the angular position of the ball. A venturi nozzle holder is used which provides a novel means of securing the adjustable venturi nozzle to the ball member. The hydro-air fitting is to be attached to a wall of a tub or pool by means of a clamping arrangement consisting of an annular abutment surface on the housing which abuts against the exterior or back of the wall that the fitting is to be mounted on and an escutcheon ring which clamps against the inner or front surface of the wall being mounted on and which is secured to the hydro-air fitting by means of a threaded nut. The nut and escutcheon ring have mating spherical surfaces that allow alignment between the fitting in a bathtub wall of an uneven thickness such that a water-tight joint is provided between the hydro-air fitting and the wall.
