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 lev...
In a pulsating spray apparatus that includes: a housing having a fluid inlet and a fluid discharge outlet; means in said housing defining a flow path from said inlet to said outlet; pulsating means in said flow path for cyclically interrupting the flow of fluid from said inlet to said outlet and causing a pulsating spray to be discharged therefrom, said pulsating means including a forced vortex driven turbine rotatable within a cavity defined with said housing; control means for adjusting the fluid flow from said inlet to said outlet; nozzle means for ta...
