A fluid-spray discharge apparatus has a housing associated with a fluid inlet. Also associated is a fluid outlet and an arrangement for effecting pulsation of fluid delivered from the inlet to the outlet. The outlet is composed of a series of spaced-apart fluid conveyances. Associated with the housing are means for enabling selection of the number of the series of conveyances operative in the flow of the fluid. Also included is an arrangement of fluid dischargers disposed outwardly of the conveyances and fluid emitters disposed inwardly of the same. Internal diverters and channels enable the provision of fluid delivery from any of the combinations of entirely from the emitters, entirely from the dischargers, in a mixture from the emitters and the dischargers, entirely from the conveyances and in a mixture from the dischargers and the conveyances.

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.
