An open-end spinning device is disclosed including a spinning rotor which is provided in a spinning-compartment housing having reduced pressure. The spinning-compartment housing has contours which correspond to the surface of the spinning rotor, with the distance between the spinning rotor and the spinning-compartment housing being relatively short. Upon rotation of the spinning rotor, the air clinging to the surface of the spinning rotor is set in motion as a result of boundary-layer friction. Because of the resulting centrifugal force and because of the short distance between the surface of the spinning rotor and the spinning-compartment housing, a stream of air is produced in the direction of the back of the spinning rotor.
