Abstract

Bei einer gattungsgemäßen Vorrichtung wird dadurch ein einfacher Aufbau der Stelleinrichtung erreicht, daß eine mit wenigstens einer mit der Durchgangsausnehmung [17] des elastischen Elements [18] kommunizierenden, durchgehenden Bohrung [51] versehene Kolbenanordnung vorgesehen ist, die den in das Düsenrohr [19], das am Düsenkopf [5] starr angebracht ist, eingreifenden Druckbolzen [20], einen hieran anschließenden, auf der vom Druckbolzen abgewandten Seite einem mit einem Druckmittel beaufschlagbaren Druckraum [45] begrenzenden Stellkolben [44] und einen hiervon auf der dem Druckbolzen [20] gegenüberligenden Seite abstehenden, einen kleineren Durchmesser aufweisenden Dichtzapfen [50] aufweist, der dichtend in eine vom Druckraum [45] abgehende, mit der zu bearbeitenden Flüsigkeit beaufschlagbare Bohrung [49] eingreift.

Figure 00000001
In the case of a device of the generic type, a simple construction of the actuating device is achieved in that a piston arrangement is provided which has at least one through bore [51] communicating with the through recess [17] of the elastic element [18] and which , which is rigidly attached to the nozzle head [5], engaging pressure pin [20], an adjoining adjusting piston [44] on the side facing away from the pressure pin and delimiting a pressure chamber [45] with a pressure medium, and one of these on the pressure pin [20 ] protruding on the opposite side, having a smaller diameter sealing pin [50], which sealingly engages in a bore [49] which extends from the pressure chamber [45] and can be acted upon by the liquid to be processed.
