Abstract
A water jet aerator for use in a tub or spa having an eyeball-type nozzle which, when rotated, controls the flow of water through the aerator. The nozzle also can be swiveled to vary the direction of fluid flow into the tub. To prevent injuries due to falling, the nozzle is recessed so as not to protrude beyond the edge of a flanged bushing which clamps the aerator to the tub wall. The nozzle is easily manipulable despite being recessed since no sleeves for controlling fluid flow surround the nozzle. Also disclosed is an embodiment in which rotating the nozzle controls air flow so as to be a function of water flow. During ganged operation of aerators, this prevents the air inlet to the aerator from being open when the water inlet is not sufficiently open to prevent the backflow of water from the tub into the air inlet.
