Abstract
An apparatus for cleaning dental tools includes an instrument connection for blowing oil and/or cleaning agent, possibly in the form of a spray mist, through the instruments and subsequently drying the instruments with compressed air. A drive unit for driving movable instrument components may additionally be provided. The control of the various cleaning phases and of the conveyance of the cleaning liquids takes place pneumatically. In particular, a short-term flow of compressed air displaces at least one piston against a spring which causes oil and/or cleaning agent to be pressed into the instrument. A control edge of the piston produces a connection between the compressed air supply and the instrument connection when the piston leaves its upper position of rest. When the piston travels back in the opposite direction under the force of the spring after the short-term flow of compressed air has ended, the supply of oil and/or cleaning agent to the instrument connection is interrupted, while the supply of compressed air is maintained until the piston has again reached its upper position of rest.
