  • Patent number: 4801091
    Abstract: The shower head dispensing device simultaneously dispenses a plurality of separate liquids in pulsating simultaneous streams. The liquid streams are maintained separate within the device by the use of separate distribution chambers, channels and nozzle sections. A free-turning, tiered rotor is provided within the device. The rotor turns on frictionless bearings provided by hydraulic balancing of the liquid pressures around the rotor. The liquid flow is maintained separate within the device and rotor and provides pulsating liquid flow through the tiers of the rotor and out through outlet openings provided in the device. Angularly adjustable nozzles are proivided within the nozzle sections and adjacent to each tier of the rotor so that the pressurized liquids flowing through the nozzles will impinge upon the outer perimeter of the rotor causing the rotor to rotate as the desired speeds.
