Abstract
Liquids for cleaning, disinfecting and lubricating dentistry handpieces are distributed to the handpieces by a device which includes reservoirs for storing liquids for the cleaning, disinfection and lubrication procedures which are to take place, and a series of solenoid valves for sequentially opening at different stations according to a prescribed cycle. To this end, each liquid to be utilized is conveyed through each handpiece in actual liquid form, and not in an atomized form, and then atomized in the handpiece by compressed air entering through a conduit which is separate from the conduit for passing the liquids.
