HIGH-PRESSURE LIQUID ROTARY NOZZLE WITH FLUID BRAKE MECHANISM
A high-pressure liquid nozzle housing encloses a self-rotating speed-controlled nozzle. The nozzle assembly structure comprises a generally cylindrical housing body forming a relatively stationary reference structure with respect to a coaxial rotatable nozzle carrying tubular shaft member contained therein. The tubular shaft member is a rotary structure having an input end in sealed relationship with a connecting high pressure liquid input member. A fluid speed brake mechanism for the spray nozzle is contained in a sealed chamber and comprises an impeller, a stator tube device and a turbine device. Rotation of the tubular nozzle shaft causes the impeller device to accelerate the flow of fluid through the stator tube device and into the turbine device, which imparts a countervailing rotational force to the rotational force generated by the sprayer head nozzle assembly attached to the end of the tubular nozzle shaft. The reduced rotational speed significantly reduces wear and heat generation at the moving parts within the nozzle assembly, and increases the effectiveness of the nozzle by increasing the dwell time of the cleaning fluid.

A rotary nozzle having a rotating shaft operating within a cylindrical housing is balanced by allowing passage of a small amount of pressurized fluid to be bled to an area between the outside of the opposite end of the shaft and the inside of the housing where the fluid force acts axially in an opposing direction upon the shaft to balance the axial inlet force exerted by the pressurized fluid.
