Abstract (en)
[origin: EP2175702A1] The nozzle (4) has a nozzle bore (4.10) for exit of a plasma gas jet at a nozzle tip (4.11). A section includes a cylindrical outer surface, and another section includes an outer surface that conically tapers towards the nozzle tip. A liquid supply groove extends over a part of the former section and over the latter section in the outer surface of the latter section towards the nozzle tip. A liquid recirculation groove is separated from the liquid supply groove and extends over the latter section. A nozzle holder (5) is provided for holding the nozzle. An independent claim is also included for a plasma torch head comprising a nozzle cap.
