Pulsating high pressure air and water nozzle
First Claim
1. A pulsating nozzle, the nozzle comprising:
- an impeller adapted to rotate about an axis;
an annular housing securing the impeller therein;
a supply aperture secured to the annular housing, wherein the supply aperture is orientated to direct a stream of pressurized fluid to impact the impeller; and
a discharge port secured to the annular housing to discharge a pulsating stream of fluid;
the impeller comprisinga plurality of radial spaced vanes positioned to cause the impeller to rotate by the stream of pressurized fluid, wherein the plurality of vanes is configured to intermittently block the discharge port as the impeller rotates to generate the pulsating stream of fluid; and
a cavity formed between each vane of the plurality of vanes, wherein each cavity having an opening and a closed bottom to fill the respective cavity with a volume of the pressurized fluid at the supply aperture and to discharge the volume of pressurized fluid back through the opening at the discharge port.

Abstract
A pulsating high pressure air and water nozzle is disclosed. The nozzle includes an impeller adapted to rotate about an axis, a housing adapted to secure the impeller therein, and a supply conduit secured to the housing. The supply conduit is orientated to direct a stream of pressurized fluid to impact the impeller to cause the impeller to rotate. The nozzle also includes a discharge port secured to the housing and is adapted to discharge a pulsating stream of fluid directly from the housing. The impeller includes a plurality of radial spaced vanes secured to a hub, where a cavity is disposed between each vane of the plurality of vanes. The plurality of vanes is adapted to intermittently block the discharge port as the impeller rotates. In addition, the nozzle includes a cover adapted to be removably secured to the housing to access an inside of the housing.
