CUTTING TORCH WITH A NOZZLE SYSTEM FOR AUTOGENOUS TORCH-CUTTING WITH A SLEEVE-LIKE PIPE JACKET FOR DRAWING IN OUTSIDE AIR

摘要

The invention relates to a nozzle system (10) having a nozzle (1) for a cutting torch (3) for autogenous torch-cutting, having a nozzle body (2) with media channels for cutting oxygen, heating oxygen or heating gas for the creation of a primary flow (4). In order to clearly reduce the noise during torch-cutting, the nozzle body (2) is surrounded in a sleeve-like manner by a tube sheathing piece (5). Therein, the inner side of the tube sheathing piece (5) has lengthwise clearances (6) on the sheathing surface of the nozzle body (2) for sucking in outside air using the suction effect of the torch-cutting media for the creation of a secondary flow (7).
