Spinning Unit for the Production of a Yarn

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 ).
