Patent ID: 7584906

Claim:
An assembly for regulating a fluid flow, comprising: a stationary and fluid supplying shaft about which is supported a rotating outer component, said shaft including an inlet for receiving the fluid flow, said outer component in communication with said shaft and including an outlet for issuing a regulated fluid flow; said rotating outer component exhibiting at least one arcuate and flow conducting surface, said rotating outer component further comprising a bottom disposed rotating nozzle plate including a plurality of individual and downwardly angled nozzles for issuing the regulated fluid flow; a three dimensional annular and interiorly hollowed disk secured to a bottom end of said shaft in sandwiching fashion between the shaft and said rotating nozzle plate, said disk and shaft defining therebetween a water jet distribution chamber, a plurality of angled fluid jet apertures formed through an annular wall in said disk redirecting fluid introduced through said shaft to said rotating nozzle plate; said rotating nozzle plate further comprising further comprising a plurality of circumferentially arrayed propelling blade portions surrounding said disk and redirecting/splitting the redirected fluid flow delivered through said angled fluid jet apertures, and for delivery to said individual and downwardly angled nozzles defined in said rotating nozzle plate, for issuing therefrom a plurality of fluid spray jets; and a fluid dampening element positioned between said shaft and said rotating outer component and restricting a rotational speed associated with said rotating outer component, in response to rotational forces imparted by the inlet fluid flow, and in order to modify at least one of a flow and pulse rate of the fluid.
