Abstract

A machine for treating objects with a treatment liquid, in particular with an etching medium, comprises a nozzle assembly, which is able to move to and fro in the manner of a drawer between a working position within the housing and a maintenance position outside the housing. In the maintenance position, nozzles located on the nozzle assembly are easily accessible for cleaning, for alignment or for being exchanged. A plug-in coupling, by which the nozzle assembly is supplied with the treatment liquid, is automatically detached when the nozzle assembly is moved out and re-closes when the nozzle assembly is guided back into its working position.
