摘要： A pump which is designed to be mounted within a recirculating water system where a portion of the recirculating water is diverted and caused to flow through the pump with this recirculating water to absorb heat that is produced during the operation of the motor. The heated diverted water is then added back to the recirculating water system. The pump includes an electric motor which is mounted within a motor housing and is completely enclosed therein. An electrically insulative mounting arrangement mounts the motor relative to the motor housing preventing the conductance of electricity therebetween. The motor housing is filled with oil thereby submerging of the electric motor in oil. The motor housing is enclosed within a seal plate. Surrounding the motor housing is an annular chamber through which the liquid is caused to flow. A baffle arrangement is located within the annular chamber to direct the flow of the liquid so that all area across the surface of the pump housing has liquid flowing thereacross. The heat that is produced in the operation of the motor is absorbed by the oil which in turn is conducted through the motor housing to be absorbed by the diverted liquid prior to being added back into the recirculating liquid system. The impeller is mounted in conjunction with a wear ring which functions to properly align the impeller.

摘要： 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.

摘要： A greater volume of air is entrained in the water flow from a hydrotherapy jet by directing the discharge from a first venturi nozzle through a second nozzle that constrains and accelerates the flow. For greatest aeration the ratio of the discharge orifice diameter for the first nozzle to that of the second nozzle is about 0.7-0.85, the ratio of the distance between the discharge orifices for the two nozzles and the diameter of the first nozzle's discharge orifice is about 0.85-1.5, air is introduced into the discharge from the first nozzle from a location fully behind that nozzle's discharge orifice, the flow of air to the downstream side of the second nozzle's discharge orifice is blocked, and the upstream end of the second nozzle overlaps the downstream end of the first nozzle.

摘要： An adjustable rotating hydrotherapy jet that rotates around primary and secondary rotation axes and includes a housing, a water inlet to the housing, and a water nozzle within the housing that forms water flowing through the inlet into a drive jet. A primary outlet is rotatably mounted on the housing about a primary rotation axis and holds the outlet downstream from the water nozzle to receive the jet flow and discharge the flow along an outlet axis. The jet flow through the primary outlet imparts a turning moment to the outlet, causing it to rotate relative to the primary rotation axis and discharge a first stage jet. A secondary outlet is rotatably mounted on the primary outlet about a secondary rotation axis to receive the jet flow from the primary outlet. The jet flow imparts a turning moment to the secondary outlet that causes it to rotate relative to the secondary rotation axis and discharge a second stage jet. The orientation of the primary outlet is adjustable with two degrees of freedom so as to adjust the orientation between the outlet and primary rotation axes, and thereby provide user control over both the outlet flow angle, coverage area and the speed of rotation.
摘要翻译：一种可调节的旋转水疗射流，其围绕主旋转轴线和次旋转轴线旋转并且包括壳体，壳体的入水口和壳体内的水喷嘴，其形成流过入口的水流入驱动射流。主出口可围绕主旋转轴线可旋转地安装在壳体上，并将出口保持在水喷嘴下游，以接收喷射流并沿出口轴线排出流。通过主出口的射流向出口施加转动力矩，使其相对于主旋转轴线旋转并排出第一级射流。次级出口围绕第一旋转轴线可旋转地安装在主出口上，以接收来自主出口的喷射流。喷射流将转向力传递给次级出口，使其相对于副旋转轴线旋转并排出第二级射流。主出口的方向可以两个自由度调节，以便调节出口和主旋转轴之间的方位，从而使用户能够控制出口流角，覆盖面积和旋转速度。

摘要： A hydrotherapy jet has a push-pull adjustment that enables a discharge to be turned off or on without rotating the discharge nozzle. This allows an off-axis discharge, useful for a neck massage, to be maintain in a constant direction despite adjustments in the discharge flow level. Inlets are provided in the rear of the nozzle, with the inlets closed off by a surrounding sleeve when the nozzle is pushed in but exposed to receive a discharge flow when the nozzle is pulled out. The sleeve is carried by a mounting member, with water flow passages to the nozzle inlet formed between the sleeve and its mounting member. The adjustment mechanism is preferably contained within a pivotable eyeball fitting, and air passageways can be added to provide a mixed water/air discharge.

摘要： An adjustable jet nozzle assembly for directing the flow of fluid through the nozzle. The assembly comprises a jet body on the exterior of the tub mounted in an aperture in the wall of the tube with a wall fitting on the interior of the tub threadably engaging the jet body. An apertured eyeball jet portion is pre-mounted in a face plate threadably engaging the wall fitting providing a smooth continuous flush appearance when installed. The eyeball jet portion is self-lubricating thereby requiring little maintenance while providing smooth operation.
