ABSTRACT:
A nozzle for the head of a plasma torch comprises a central aperture and is provided with a plurality of cooling channels uniformly distributed around the central longitudinal axis of the nozzle in a polar configuration. Each of the cooling channels comprises a first cooling channel portion and a second cooling channel portion communicating with the first one and enclosing an angle between each other. The first cooling channel portions extend radially towards the central longitudinal axis of the nozzle and at least approximately perpendicularly thereto. The second cooling channel portions extend under an acute angle with respect to the central longitudinal axis. By this design, a substantially more uniform and more effective cooling of the nozzle is achieved, with the result that the useful working life is prolonged.
