ABSTRACT:
A hydro-therapy spa jet including an inlet connection, a first nozzle to accelerate a water stream from the inlet connection, an air inlet, a second nozzle drawing air from the air inlet to aerate the accelerated water stream, and a third nozzle to slow and directionally adjust the aerated water stream. The third nozzle includes an inlet, a chamber, and an orifice, where the aerated water stream passes into the inlet, through the chamber, and out the orifice. The inlet has a conical inner surface that contracts in a downstream direction. The inlet also includes a spherical outer surface, which is received in a conforming spherical inner surface within the jet. The chamber is conical in shape, expanding in the downstream direction to reduce the water's speed as it passes through the chamber. The orifice defines a passage having a cross-sectional area that is constant in the downstream direction. The third nozzle includes one or more long, tapered vanes fixed within the chamber, dividing the chamber into a plurality of segments. The vanes have a thick, rounded upstream end, and taper down to a pointed downstream end. The third nozzle also includes a rounded, teardrop-shaped protrusion extending upstream within the third nozzle. The protrusion is suspended within the third nozzle on the vanes, and has a cross-sectional area that decreases in the downstream direction.
