Abstract: A hydrotherapy jet assembly that produces rotating and pulsating streams of water and provides for user adjustable flow control, and user adjustable control of the speed of rotation independently of the flow control. The assembly includes a nozzle rotor supported for rotation in a generally cylindrical body, and a rotor retainer cage having a thrust plate that applies an axial retaining force to the rotor. The rotor has two internal passages that discharge water in directions that may be selected to produce a turning moment applied to the rotor. Fins may be incorporated into the rotor to produce or contribute to rotation. In all of the disclosed forms of the rotor, radial thrust components resulting from discharge of water through the two rotor passages cancel each other. The rotor is thereby balanced in directions transverse to its axis or rotation. Axial thrust components resulting from the discharge of water from the nozzle rotor are substantially balanced by the force of water entering the rotor.

Abstract: A hydrotherapy apparatus incorporating a water wheel coupled to a reduction gear assembly for providing a strong jet of water at an extremely uniform rate of rotation, even at slow rotational speeds. The water wheel has a relatively small diameter so that it may be driven at a high rate of speed to minimize any rotational speed variations of the water wheel itself. The water wheel is non-rigidly coupled to the drive shaft of the nozzle by a helical gear which causes the drive shaft to rotate at a slower rate than that of the water wheel.

Abstract: A washing device for parts of human body comprises a thermostatic mixing valve which is disposed at a junction of a cold water supply passage and a heated water supply passage, a latching solenoid valve which is mounted on a heated water drainage passage branched out from said heated water supply passage and a latching solenoid valve which is mounted on a mixed hot water supply passage. Due to such construction, electric power for heating water is no longer necessary in the toilet bowl and electric power for mixing heated water and cold water to produce mixed hot water to be ejected from an ejecting nozzle also becomes unnecessary. Furthermore, electric power for operating the solenoid valve is minimized by means of a latching solenoid. Accordingly, the overall consumption of electric power necessary for operating and controlling the washing device can be minimized thus enabling the use of a small dry cell or battery as an electric power source of the washing device.
