Abstract

The invention relates to a spinning unit of the air-jet spinning machine, which serves the purpose of producing a yarn (2) from a fiber composite (3), whereas the spinning unit (1) possesses a spinning nozzle (4) with a vortex chamber (6) featuring an inlet opening (5) for the fiber composite (3), whereas the spinning unit (1) features air jets (21) directed into the vortex chamber (6), which flow into the vortex chamber (6) in the area of a wall (7) surrounding the vortex chamber (6) and through which air jets, during operation of the spinning unit (1), compressed air can be introduced into the vortex chamber (6) in a given direction of rotation, in order to confer upon the fiber composite (3) a rotation in the specified direction of rotation, and whereas the air jets (21) are connected to a source of compressed air (9) with the assistance of at least one fluid connection (8). In accordance with the invention, it is provided that the spinning unit (1) includes at least one replaceable throttle element (10), with the assistance of which the volume flow of the compressed air, which flows from the source of compressed air (9) into the vortex chamber (6) during the operation of the spinning unit (1), is limited, whereas the throttle element (10) is placed in the flow path of the compressed air between the source of compressed air (9) and the air jets (21).
