Abstract

Apparatus for sealing a rotor housing of an open-end spinning machine is disclosed wherein the housing is under a reduced-pressure and includes a bore through which a rotor shaft of the spinning rotor extends. The apparatus includes a mounting carried by the rotor housing for floatingly mounting a sealing washer relative to the bore of the housing and a counter-surface carried adjacent the reduced-pressure side of the housing against which the sealing washer is abutted and maintained by the reduced pressure in the housing.
