Abstract
A pulsating spray nozzle has a number of features including the introduction into the outer periphery of a forced vortex of a speed-control fluid. In such a forced-vortex environment, a floating turbine is enabled by means of paths correlated with outlet openings better to avoid stalling. Improved dimensioning of elements in the forced-vortex-turbine approach also contributes in that direction. A regulator limits the rate of flow of fluid through the device to a predetermined maximum amount upon increase of incoming water pressure beyond a selectable level.
