摘要：
This application relates to a nozzle (3) for a liquid-cooled plasma cutting torch, having at least one groove (6a) which is arranged on an outer wall (4) of the nozzle (3) with which the liquid makes contact, is oriented with the direction of its longitudinal axis (18) approximately perpendicular to the nozzle mid-axis (17) of the nozzle (3) and reduces the wall thickness (15) of the nozzle (3), at least in this region, and has a groove base (12, 13) that reaches into the wall thickness (15), wherein the groove base (12, 13) of the groove (6a) is formed so as to be approximately parallel to the contour of the inner wall (5) of the nozzle (3).
