 EMI2.1 
 der Membrane beim Abnehmen des Druckes. 



   Bei der Verwendung der Rollmenbrane in Steuerventilen von Druckluftbremsen kann die unter Umständen in der Druckluft enthaltene Feuchtigkeit auf die Gummimembrane und die matallisehen Teile des Gehäuses nachteilig wirken ; dem kann man dadurch begegnen, dass man in das Gehäuse eine Büchse einsetzt, die nicht aus Metall, sondern beispielsweise aus Bakelit oder einem ähnlichen Stoff hergestellt ist, der bei der Bearbeitung völlig glatt wird. 



   PATENT-ANSPRÜCHE :
1. Membrane zur Abdichtung eines in einem Gehäuse verschiebbaren kolbenartigen Teiles, die bei ihrer Bewegung an den Gehäusewandungen abrollt, dadurch gekennzeichnet, dass sie als hohler,   eingestülpter   Kegelstumpf ausgeführt ist, der seine Rollbewegung auf entsprechend   konisehen   Gehäusewandungen ausführt.

 EMI2.1
 the membrane when the pressure is removed.



   When using the roll diaphragm in control valves of compressed air brakes, the moisture contained in the compressed air can have a detrimental effect on the rubber membrane and the metal parts of the housing; This can be countered by inserting a sleeve into the housing that is not made of metal, but, for example, of Bakelite or a similar material that becomes completely smooth when processed.



   PATENT CLAIMS:
1. Membrane for sealing a piston-like part displaceable in a housing, which rolls on the housing walls when it is moved, characterized in that it is designed as a hollow, inverted truncated cone, which carries out its rolling movement on corresponding conical housing walls.

Claims (1)

2. Rollmembrane nach Anspruch 1, dadurch gekennzeichnet, dass die Membrane in jede ihrer Endlagen durch die Gehäusewandung vollständig abgestützt wird. 2. Rolling membrane according to claim 1, characterized in that the membrane is completely supported in each of its end positions by the housing wall. 3. Rollmembrane nach Anspruch 1, dadurch gekennzeichnet, dass die Membrane in ihrer Mitte durch einen Kolben gestützt wird, der im entgegengesetzten Richtungssinn wie das Kolbengehäuse konisch gestaltet ist, um die Breite der durch den Druck belasteten, nicht an dem Kolben oder der EMI2.2 konstant zu halten. 3. Rolling membrane according to claim 1, characterized in that the membrane is supported in its center by a piston which is conical in the opposite sense of direction as the piston housing, to the width of the loaded by the pressure, not on the piston or the EMI2.2 keep constant. 4. Rollmembrane nach den Ansprüchen 1 und 3, dadurch gekennzeichnet, dass bei nur einseitig durch Druckmittel beaufschlagter Membrane die dem Druckmitteleinlass abgewendete Seite von einem festen, dichtmaschigen Gewebe bedeckt ist, das die Gestalt der Membrane besitzt und mit ihr abrollt. 4. Rolling membrane according to claims 1 and 3, characterized in that when the membrane is acted on only on one side by pressure medium, the side facing away from the pressure medium inlet is covered by a solid, tightly meshed fabric which has the shape of the membrane and rolls with it. 5. Rollmembrane nach den Ansprüchen 1 bis 4, dadurch gekennzeichnet, dass die mit der Membrane in Berührung kommenden Innenteile des Gehäuses aus einer gegen Feuchtigkeit unempfindlichen Masse, beispielsweise Bakelit od.. dgl., bestehen, EMI2.3 5. Rolling membrane according to claims 1 to 4, characterized in that the inner parts of the housing coming into contact with the membrane are made of a moisture-resistant mass, for example Bakelite or the like.
