摘要：
The invention relates to a nozzle system (10) with a nozzle (1) for a cutting torch (3) for autogenous torch cutting, comprising a nozzle body (2) with media channels for cutting oxygen, heating oxygen and heating gas in order to generate a primary flow (4). The nozzle body (2) is surrounded by a sleeve-like pipe jacket (5) in order to significantly reduce the noise during torch-cutting. The inner side of the pipe jacket (5) has free spaces (6) longitudinally aligned towards the outer surface of the nozzle body (2) for drawing in outside air by means of the suction effect of the torch-cutting media so as to generate a secondary flow (7).
