  Kompensator zum Ausgleich von Längenänderungen in Rohrleitungen 
Es sind Kompensatoren mit einer Dilatationsfalte aus Gummi in Form eines flach-   gedrücktenS   bekannt, bei welchen Metallreifen in diese Falte hineinreichen. Die Ränder dieser Verbindung müssen von Zeit zu Zeit mit Schmiermitteln versehen werden, um einen zu   grossenverschleiss   zu verhindern, was Arbeit und zusätzliche Instandhaltungskosten verursacht. Auch sind diese Verbindungen nur für kleine Drücke verwendbar, da bei hohen Beanspruchungen die S-Falte sich aufbläht und reisst. 



   Vorliegende Erfindung bezweckt, diese Nachteile zu vermeiden. Sie liegt darin, dass der Kompensator zum Ausgleich von Längen- änderungen in Rohrleitungen aus einem, an sich bekannten, im mittleren Bereich mit einer Dilatationsfalte mit halbwellenförmigem Längsschnitt versehen, aus nachgiebigem elastischem Material, insbes. Gummi, hergestellten Rohrstück und aus ebenfalls an sich bekannten, die   walzenförmigen Teile   des Rohrstückes von aussen umgebenden Versteifungsreifen besteht. Diese Versteifungsreifenkönnen inStützringe eingesenkt und even-   tuell mit   ihnen verbunden, angeheftet werden, sie sind an dem der Dehnungsfalte des Kompensators zugewendeten Ende mit einer Verstärkung versehen. 



   Weitere Einzelheiten und Vorteile der Erfindung werden an Hand eines auf der Zeichnung im Längsschnitt durch den Kompensator dargestellten   Ausführungsbeispieles er-   läutert. 



     DerKompensator l   aus Gummi ist mittels Schrauben 2 und Schraubenmuttern 3 zwischen den Flanschen 4 und den Stützringen (losen Flanschen) 5 montiert. Die Flanschen 4 sind an beiden Seiten an die Rohrleitung 6 angeschweisst. Die Stützringe 5 bilden die inneren Gegenflanschen des Gummi-Kompensators. 



  Die   walzenförmigen Teile   des Kompentators, das sind die Teile 1 ausser der Dehnungsfalte 9, sind von Versteifungsreifen 7 umgeben, welche sich an die im Längsschnitt halbwel-

  Compensator to compensate for changes in length in pipelines
Compensators with a dilation fold made of rubber in the form of a flattened S are known, in which metal tires extend into this fold. The edges of this connection have to be lubricated from time to time in order to prevent excessive wear, which causes labor and additional maintenance costs. These connections can only be used for low pressures, since the S-fold expands and tears under high loads.



   The present invention aims to avoid these disadvantages. It lies in the fact that the compensator is provided to compensate for changes in length in pipelines from a known per se, in the middle area with a dilation fold with a semi-undulating longitudinal section, made from flexible elastic material, especially rubber, and from a pipe section also known per se , the cylindrical parts of the pipe section from the outside surrounding stiffening tires. These stiffening hoops can be sunk into support rings and possibly connected to them or attached, they are provided with a reinforcement at the end facing the expansion fold of the compensator.



   Further details and advantages of the invention are explained with reference to an embodiment shown in the drawing in a longitudinal section through the compensator.



     The compensator 1 made of rubber is mounted between the flanges 4 and the support rings (loose flanges) 5 by means of screws 2 and screw nuts 3. The flanges 4 are welded to the pipeline 6 on both sides. The support rings 5 form the inner counter flanges of the rubber compensator.



  The cylindrical parts of the compensator, that is, the parts 1 except for the expansion fold 9, are surrounded by stiffening tires 7, which are attached to the semi-circular in longitudinal section
