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.

Two-axis rotating hydrotherapy jet with adjustable nozzle orientations

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.
