ABSTRACT:
An apparatus for treating, for example cleaning, sensitive, in particular highly contoured surfaces such as those of sculptures of wood, plaster, bronze and the like, comprises a mixing head (1) for mixing media supplied to the mixing head (1) and for spraying a treatment jet (50) formed therefrom. The mixing head (1) comprises a mixing chamber (30) into which under pressure a first jet with a liquid treating agent is introduced via a first supply conduit (10) through an inlet (12) and a second jet is introduced, the jet axis (22) of which is inclined at an angle (.gamma.) to the jet axis (11) of the first jet and extends eccentrically thereto. In this apparatus the inlet (12) for the first jet comprises an inlet opening (14) which is so formed and/or orientated that the jet axis (22) of the second jet intersects the first jet. The treatment of sensitive highly contoured surfaces is carried out according to the invention, in particular using this apparatus, by means of a treatment jet (50) rotating about its generating jet axis (11) and containing at least a treating agent liquid before its atomization.
