ABSTRACT:
A labyrinth seal of a shaft comprises ring plates arranged in an alternating fashion in parallel with one another and coaxially with the shaft. One set of plates are rigidly fixed to the shaft and the other set of plates are fixed to a stationary sleeve. According to the invention, the sleeve has at least one through passage arranged in a plane intersecting the axis of the shaft and extending at angle ranging from about -60.degree. to about +60.degree. to a radial plane running at right angle to the axis of the shaft. The passage terminates at one end in the space between adjacent plates to remove the fluid under action of centrifugal force during rotation of the shaft.
