|1. (WO2018077576) DEVICE FOR ABRASIVE FLUID-JET CUTTING|
|Applicants:||ROBERT BOSCH GMBH
|Title:||DEVICE FOR ABRASIVE FLUID-JET CUTTING|
Device for abrasive fluid-jet cutting with a compressor unit (1) for compressing a fluid, which can be fed to a nozzle (25) in the form of a stream of high-pressure fluid, wherein the nozzle (25) is designed for discharging a high-pressure fluid jet (33). The stream of fluid to the nozzle (25) can be interrupted, or at least greatly restricted, by an interrupter unit (6), wherein the interrupter unit (6) comprises a control chamber (8), which can be filled with high-pressure fluid and can be connected to a drainage chamber (19) by way of a control valve (14). The quantity of control fluid removed by way of the control valve (14) flows through a feed line (20) into a mixing chamber (27), wherein an abrasive channel (22) carrying abrasive particles opens out into the feed line (20) and the quantity of control fluid mixes with the high-pressure fluid jet (33).
