摘要

#CMT# #/CMT# 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. #CMT# : #/CMT# An independent claim is also included for a plasma torch head comprising a nozzle cap. #CMT#USE : #/CMT# Nozzle for use in a head of a liquid-cooled plasma torch (claimed) that is utilized for plasma arc cutting of workpieces and for welding edge preparation. #CMT#ADVANTAGE : #/CMT# The design configuration of the nozzle avoids overheating between one section of the nozzle and the nozzle holder in the vicinity of a nozzle channel and the nozzle bore in a simple way. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a plasma torch head with a plasma and secondary gas inlet consisting of a nozzle and a nozzle cap. 1 : Plasma torch head 4 : Nozzle 4.10 : Nozzle bore 4.11 : Nozzle tip 5 : Nozzle holder.
