   Die Ausführungsform nach der Fig. 3 unterscheidet sich von den beschriebenen   Ausführungs-   formen dadurch, dass die Dichtungsrippen e nicht zu den Schirmen c parallel, sondern ein wenig in der entgegengesetzten Richtung gegen die Welle a geneigt sind. Dadurch wird erzielt, dass bei gegebenenfalls eintretenden Deformation der Rippen e infolge des auf sie wirkenden Dampfdruckes auch die von ihren Rändern gebildeten Spalten fi verkleinert werden. Eine selbsttätige Verengung   sämtlicher   Spalten/ und fi kann bei der Ausführungsform nach der Fig. 3 dadurch erzielt werden, dass auch die Dichtung, rippen e als elastische Schirme ausgebildet und ebenso wie die   Dichtungsringe   c bei der   Ausfiihrungs-   form nach Fig. 2 mit dem feststehenden Turbinenteil verbunden werden. 



   PATENT-ANSPRÜCHE :
1. Labyrinthdichtung nach Patent Nr. 99776, bei der die feststehenden Dichtungsrippen starr sind, dadurch gekennzeichnet, dass diese in der Strömungsrichtung des Dampfes unmittelbar hinter den elastischen Schirmen   (e)   angeordnet sind, so dass zwischen beiden enge   Durchflussspalten   (g) liegen, die durch den Dampfdruck noch weiter verengt werden. 



   2. Labyrinthdichtung nach Patent Nr. 99776, dadurch gekennzeichnet, dass die sich mitdrehenden, untereinander parallelen   Schirme (c)   die entgegengesetzte Neigung haben, wie die gleichfalls untereinander parallelen, feststehenden Dichtungsrippen (e), so dass die von sämtlichen Dichtungsringen   (c,   e) gebildeten äusseren und inneren Ringspalten (f   und tl) durch   den   Dampfdruck   verengt werden (Fig. 3).

   The embodiment according to FIG. 3 differs from the embodiments described in that the sealing ribs e are not parallel to the screens c, but rather are inclined slightly in the opposite direction towards the shaft a. This means that if the ribs e are deformed as a result of the steam pressure acting on them, the gaps fi formed by their edges are also reduced. An automatic narrowing of all gaps / and fi can be achieved in the embodiment according to FIG. 3 in that the seal, ribs e are also designed as elastic screens and, like the sealing rings c in the embodiment according to FIG Turbine part are connected.



   PATENT CLAIMS:
1. Labyrinth seal according to patent no. 99776, in which the stationary sealing ribs are rigid, characterized in that they are arranged in the direction of flow of the steam immediately behind the elastic shields (e), so that there are narrow flow gaps (g) between the two be narrowed even further by the steam pressure.



   2. Labyrinth seal according to patent no. 99776, characterized in that the rotating, mutually parallel screens (c) have the opposite inclination as the also mutually parallel, fixed sealing ribs (e), so that the sealing rings (c, e ) formed outer and inner annular gaps (f and tl) are narrowed by the steam pressure (Fig. 3).
