<p>The invention lies in the field of fluid valves and discharge nozzles and more particularly pertains to fluid discharge nozzles wherein a particular discharge pattern, having an automatic continuously changing direction, is desired. The fluid discharge nozzles have particular application in hydrotherapy and are adapted to discharge a turbulent air-water admixture for this purpose. The valves disclosed herein are constructed so as to produce a discharge jet of an intimate water-air admixture, the discharge pattern being generated covering a conical or annular surface of revolution or variations thereof. The valves disclosed herein also produce a discharge jet which is readily variable in its rate of discharge of the intimate admixture of air and water. The fluid valve of this invention is therefore capable of therapeutic massaging action over a continuously changing surface area.</p> |
