The nozzle has a mouthpiece (12) comprising an outlet (30) and a discharge chamber (34) tapering to the outlet. The outlet clamps a curved surface, and a surface (32) surrounding a boundary (38) of the outlet abut against the boundary of the outlet at each point of the boundary in a radial direction at an angle between 65 and 95 degrees to a central longitudinal axis. The boundary of the outlet is formed in sections by using chamfers, where the mouthpiece is formed from hard metal. The mouthpiece is sealed against a sealing housing by a metal joint. |
