Multifunctional nozzle for a spinning machine

A multifunctional nozzle for a spinning machine, comprising;

• a pressurisable nozzle housing with a nozzle channel which extends along a longitudinal axis direction of the pressurisable nozzle housing and is open on one side along the longitudinal axis direction;
• a fluid inlet for admitting a pressurised fluid into the nozzle channel to bring about a vortex flow within the nozzle channel;
• a nozzle body designed to be arranged in the nozzle channel or to be formed in the nozzle channel together with the pressurisable nozzle housing, wherein the nozzle body is shorter than the nozzle channel along the longitudinal axis direction and has a through-duct which extends along the longitudinal axis direction for guiding through a thread or a fibre band;
• an annular gap which extends in the nozzle channel along the longitudinal axis direction and has at least one narrow point towards which the annular gap tapers on both sides along the longitudinal axis direction, wherein the at least one narrow point is formed downstream of the fluid inlet along the longitudinal axis direction;
• a delimiting part designed to be formed or arranged in the nozzle channel in a manner closing the pressurisable nozzle housing on a side of the fluid inlet that faces away from the at least one narrow point, wherein the delimiting part has a further through-duct extending along the longitudinal axis direction for the thread or the fibre band for communicating with the through-duct of the nozzle body;
• and
• a hollow-body-like flow conducting body designed to guide the thread or the fibre band in a manner accompanied by fluid between the annular gap and an open end of the nozzle channel;
• wherein the annular gap is formed between the nozzle body and the pressurisable nozzle housing and/or the hollow-body-like flow conducting body.
