Multifunctional nozzle for a spinning machine

The present invention relates to a multifunctional nozzle (100; 200; 300) for a spinning machine, by means of which nozzle at least one improved real-twist yarn can be produced, in particular without a core of untwisted, in particular parallel, fibres (FS). The multifunctional nozzle (100; 200; 300) furthermore makes it possible to generate a real-twist yarn in which advantages of an open-end yarn can be combined, at least in part, with those of a ring yarn. For this purpose, the multifunctional nozzle (100; 200; 300) comprises a pressurisable nozzle housing (2) with a nozzle duct (2A), which extends along a longitudinal axis direction (A) of the nozzle housing (2) and is open on one side along the longitudinal axis direction (A). In addition, a fluid inlet (13) is provided for admitting a pressurised fluid into the nozzle duct (2A) to bring about a vortex fluid flow (W) within the nozzle duct (2A). A nozzle body (1) can be arranged in the nozzle duct (2A) or formed in the nozzle duct together with the nozzle
