Machine for treating objects with a treating liquid
First Claim
1. In a machine for treating objects with a treatment liquid such as an etching medium which includesa housing (1) having a side opening (43) which can be closed,at least one nozzle assembly (20) which includes a plurality of nozzles and from which the treatment liquid is sprayed onto the objects to be treated, the improvement comprising that(a) said nozzle assembly (20) is mounted within said housing so that it can be withdrawn in the manner of a drawer from a first working position within the housing (1) outwardly through said side opening (43) of the housing (1) to a second position in which it extends laterally outwardly from the interior of the housing (1) so that the nozzles (25) are easily accessible for inspection or maintenance, and(b) cooperating plug-in coupling members (28, 35) are provided in said housing (1) and on said nozzle assembly (20) by which the nozzle assembly (20) is in a first position connected to a source of treatment liquid and in a second position is automatically disconnected from the source of treatment liquid when the nozzle assembly (20) is withdrawn outwardly through said side opening (43).

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.
