Claims
- 1. A hydro-therapy spa jet nozzle for decelerating an aerated water stream to be propelled against a person's anatomy, comprising:
- a body defining a chamber having an upstream end and a downstream end;
- an inlet at said body's upstream end for receiving the aerated water stream, and delivering it into the chamber;
- an orifice leading from the chamber at said body's downstream end, for propelling the aerated water stream against the person's anatomy; and
- at least one vane fixed within the chamber and extending from the inlet to the orifice, said at least one vane having a thickness that tapers down in the downstream direction;
- wherein the chamber expands in a downstream direction from said inlet to said orifice.
- 2. The hydro-therapy spa jet nozzle of claim 1, wherein:
- said at least one vane has an upstream end that is rounded; and
- said at least one vane divides the body chamber into a plurality of segments leading from said inlet to said orifice, said segments expanding in the downstream direction.
- 3. The hydro-therapy spa jet nozzle of claim 1, wherein said inlet contracts in a downstream direction.
- 4. The hydro-therapy spa jet nozzle of claim 1, and further comprising an outer surface around said inlet, having an annular section that is spherical in shape.
- 5. The hydro-therapy spa jet nozzle of claim 1, wherein said orifice has a cross-sectional area that is constant in the downstream direction.
- 6. The hydro-therapy spa jet nozzle of claim 1, and further comprising a rounded protrusion extending upstream within said body;
- wherein said protrusion has a cross-sectional area that decreases in the downstream direction; and
- wherein said protrusion is suspended within said body on said at least one vane.
- 7. A hydro-therapy spa jet nozzle for decelerating an aerated water stream to be propelled against a person's anatomy, comprising:
- a body defining a chamber having an upstream end and a downstream end;
- an inlet at said body's upstream end for receiving the aerated water stream into the chamber;
- an orifice leading from said chamber at said body's downstream end, for propelling the aerated water stream against the person's anatomy; and
- a rounded protrusion extending upstream and contained entirely within said body and said inlet, said protrusion tapering downwardly in the downstream direction;
- wherein the chamber expands in a downstream direction from said inlet to said orifice.
- 8. The hydro-therapy spa jet nozzle of claim 7, wherein said protrusion has a cross-sectional area that decreases in the downstream direction.
