Hydromassage apparatus

摘要

Hydromassage apparatus for a whirlpool bath system includes a novel adjustable nozzle assembly adapted to be mounted on the wall of a bathtub or other water holding receptacle to directionally discharge a high velocity jet stream of fluid. The system includes a novel, venturi type, air injector for introducing air flow and intermixing air and water to form a high velocity, turbulent stream of fluid which is discharged from the directional nozzle assembly. The system further includes a novel air inlet control valve for selectively controlling the amount of air introduced into the water stream in the injector and the valve is also provided with a safety shut off capability for preventing the back-flow of water out through the air inlet passage.
