Fluid-powered liquid-dispenser apparatus

摘要

A tool powered by pressurized liquid, typically water, for treatment of a variety of surfaces ranging from natural to manufactured, has a scrubber wheel powered by the pressurized liquid. A treatment liquid is contained in a single-use, throw-away cartridge mounted in the tool. The cartridge is mounted in the tool for rotation therein when desired. A nozzle in the tool for discharging the pressurized liquid onto the scrubber wheel to rotate the scrubber wheel, is movable by the tool operator during a treatment operation to change the direction of discharge to the extent desired to drive the scrubber forward or backward and to rotate the cartridge to dispense the treatment liquid if, and when, dispensing of the treatment liquid is desired.
