ABSTRACT:
A hydrotherapeutic aerator assembly for mixing air as fine bubbles into the center of a stream of pressurized water has a swivelable ball carrying a nozzle in which mixing of air and water occurs before ejection of the stream into a pool or bath. A housing containing the ball and nozzle has half of a ball socket formed therein. A one-piece ball seal and retaining member attachable to the housing forms a second half of the ball socket. The nozzle is adjustable axially within the ball on cooperating threads and is made non-removable from the ball by a radially-extending O-ring snapped into a channel in a rearward part of the nozzle. A circumferential abutment surface in the ball prevents withdrawal of the nozzle beyond a selected position.
