Abstract:
A spa comprised of a fluid enclosure having a floor and an upstanding sidewall includes a therapy station within the enclosure. The therapy station includes an upright seat to accommodate a single person and includes a plurality of fluid jets in the footwell and sidewall of the enclosure at various targeted hydrotherapy locations. Pressurized water is provided to the hydrotherapy locations by a pair of fluid pumps. Each jet at the hydrotherapy locations is provided with a variable flow controller adapted to control the water flow out of the jet. Each hydrotherapy location is also provided with a variable flow controller adapted to control the flow of air into the jet. Each hydrotherapy location is also provided with a directional flow controller. Each jet discharges water flow at one horsepower or more to provide intense hydrotherapy selectably directed to multiple portions of the body simultaneously or individually.
Abstract:
A multiple nozzle moving jet structure for a spa, attached to flexible tubes encased in an articulated sleeve exhausts pressurized water into the spa in a vertical whipping motion, in reaction to the water exhaust. The multiple nozzle structure utilizes one air supply tube to aerate water streams of the multiple nozzle structure. The combination of the multiple nozzle structure with the articulated sleeves on the flexible tubes, confines movement of the nozzle structure in one plane, eliminating the requirement for a guide body to confine direction of nozzle movement.
Abstract:
Systems, methods, and valve assemblies for providing pressurized water to a plurality of water inlets in a bathing enclosure are disclosed. Aspects of the systems, methods, and valve assemblies disclosed overcome limitations of the prior art by allowing a bather to vary the flow of pressurized water out of one or more water jets without varying the flow of water from the pump supplying the water. The systems and methods include valve assemblies that allow the bather to divert the flow of pressurized water away from the water jets. The diverted flow may be introduced to the bathing enclosure wherever convenient, for example, to a foot well. A bather may divert the flow by manually actuating a pressure relief valve having a spring-actuated orifice. The inventions are applicable for any type of bathing enclosure including a pool, a tub, a spa, a shower, or a bath.
Abstract:
A spa jet for delivering water from an upstream source of water under pressure to the interior of a spa, the spa jet having a housing with an inlet tube communicating with the source of water and a chamber wall defining a generally cup shaped chamber. A retaining ring is connected to and inside of the chamber wall. A form having an annular upstream portion is fixed against axial movement between the chamber wall the retaining ring. The form has a downstream portion extending from the annular portion in the form of a shaft aligned with the axis. The spa jet also has a rotor with a generally cylindrical body concentric with the axis, the body having a bearing surface extending around the shaft which supports the body for rotating. At least one nozzle passage extends through the rotor which collects water from the inlet tube and directs the water as a water jet into the spa at an angle sufficient to impart a turning moment to the rotor about the axis. A keeper is fixedly secured to a free end of the shaft overlapping portions of at least one of the body and the bearing, the keeper retaining the body on the shaft.
Abstract:
A spa jet comprising a first nozzle, a second nozzle, and an aeration chamber therebetween, are all disposed in a housing. One seal forms a watertight seal between the first nozzle and the housing, and another seal forms a watertight seal between the second nozzle and the housing. A ring is affixed to the second-nozzle downstream end, and a third nozzle is pivotally mounted in the ring. A retainer is mounted to the ring and it frictionally secures the third nozzle in any one of a continuum of angular positions. The ring can be a ball-bearing ring, whereby the third nozzle can freely rotate in the ball-bearing ring under the force of a water stream exiting the third nozzle. A non-circular opening in the third nozzle assists in rotating the third nozzle even when centered in the ring. A barrel, comprising the first and second nozzles and the aeration chamber, has latching tabs formed thereon, and the housing has a retaining profile formed therein for engaging the latching tabs. A scallop has slots formed therein, and the barrel has snap tabs formed thereon for releasably engaging the slots. The housing is secured to a spa wall by a nut. A compensation spacer is disposed between the nut and the spa wall to absorb spa wall irregularities.

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.
Abstract:
An adjustable rotating hydrotherapy jet has a rotatable support structure for a jet outlet nozzle that holds the outlet nozzle with its axis offset from the rotation axis, and at a non-intersecting and non-zero angle thereto. The jet flow through the outlet nozzle thus imparts a turning moment to the support structure, causing it to rotate along with the nozzle. The outlet is preferably provided as an eyeball-type fitting, with the eyeball adjustable over a range of angles relative to its support structure to allow for a selection of the jet's angle and rotational speed; this preferably includes an adjustment position at which the eyeball axis is parallel to the rotational axis and the jet does not rotate. A tab in the eyeball's support structure preferably lodges in a track in the eyeball member to restrict the eyeball adjustment to a plane that develops the maximum rotational thrust.
Abstract:
A nozzle assembly for discharging a mixture of first and second fluids includes a housing having inlets for introducting the first and second fluids into the housing; and a sleeve disposed in and affixed to the housing and receiving the second fluid from one of the inlets. There is further provided a holding ring disposed in the housing and surrounding the sleeve. The holding ring may be displaced relative to the sleeve in a direction parallel to the sleeve length. A nozzle body is situated in the housing and has a spherical member surrounding the sleeve and a nozzle outlet member. The nozzle body has a sealing face situated inside the spherical member and cooperating with a spherical sealing face of the sleeve for determining therewith a variable annular gap constituting a flow passage area for the first fluid. The nozzle body is held captive in the holding ring and may pivot therein. The nozzle body and the holding ring move substantially as a unit upon longitudinal displacement of the holding ring. The size of the variable annular gap depends from the longitudinal position of the holding ring. The holding ring has a limit position in which the gap is reduced to zero by a sealing contact between the spherical sealing face of the sleeve and the sealing face of the nozzle body. In the limit position the center of the spherical member and the center of the spherical sealing face of the sleeve coincide.
