Abstract
The invention relates to a nozzle for a tool for working material, for example for laser cutting. The nozzle contains an electrically conducting nozzle body (2), at the tip of which is arranged a nozzle electrode (12) electrically insulated from it. A cap element (15) accomodates the nozzle electrode (12) and is in engagement with the nozzle body (2). At the same time, the cap element (15) presses the nozzle electrode (12) against an insulating body (9). The cap element (15) and the nozzle electrode (12) are insulated from one another by means of an electrically non-conducting layer, making possible shielding of the nozzle electrode (12) a long way into the tip region. The cap element (15) furthermore protects the nozzle electrode (12) from lateral forces in order to avoid damage to the insulating body (9) which accommodates the nozzle electrode (12).
