Beschreibung
Zusammenfassung:	The invention relates to a device for the erosive processing and/or the cleaning of a material or of a material surface by means of at least one high-pressure fluid jet, comprising a nozzle (1) for outputting a high-pressure fluid jet and an apparatus (2) arranged upstream of the nozzle (1) for producing a pulsed high-pressure fluid jet, wherein the apparatus (2) comprises at least one valve (3). According to the invention, the valve (3) is designed as a servo valve and has an axially movable valve piston (4) for connecting a valve feed (5) to a valve outlet (6) such that the flow through the valve (3) can be specified by means of the axial position of the valve piston (4). The invention further relates to a method for operating a device according to the invention.
