A fluid-flow valve or nozzle discharging a stream of continuously changing direction, particularly for use as a shower head or for use in hydrotherapy to discharge a fluid stream or a turbulent jet of an intimate water-air admixture, respectively, the preferably adjustable discharge pattern covering a conical or annular surface of revolution, or variations thereof. The valve or nozzle comprises a body, a moveable rotor chamber coaxially mounted within the valve body, and a rotor body within the rotor chamber. Water and air are fed to inlets and to pass through the bore of the moving rotor body, and discharged through a flared mouth where a control knob can be rotated to influence the fluid flows and the motion of the rotor body.
