Description

Die Erfindung behandelt eine Vorrichtung zum Abdichten der Eintrittsstelle der Kolbenstange in den Zylinderraum bei Flüssigkeitsbremsen, insbesondere für Puffer von Schienenfatueeugen, bei der eine elastische Manschette vorgesehen ist, die mit dem einen Ende ian dem Zylinder und mit ihrem andern Ende an der Kolbenstange befestigt ist. Abweichend von bisherigen Ausführungen ähnlicher Art ist die Manschette gemäß der Erfindung so angeordnet und ausgebildet, daß sie die vom Arbeitskolben aus dem Zylinderraum verdrängte Flüssigkeit unter Ausdehnung ihrer Wandung aufnimmt und die Flüssigkeit nach Zurückgehen des Kolbens infolge ihrer elastischen Eigenschaft wieder in den Zylinderraum zurückdrängt.The invention relates to a device for sealing the entry point of the piston rod in the cylinder space with liquid brakes, especially for buffers of rail figures, in which an elastic cuff is provided, which with one end ian the cylinder and with its other end End is attached to the piston rod. Different from previous statements, more similar Art, the cuff according to the invention is arranged and designed so that it removes the working piston from the cylinder chamber absorbs displaced liquid with expansion of its wall and the Liquid again after the piston has moved back due to its elastic properties pushed back into the cylinder space.

Abb. r der Zeichnung ist ein Längsschnitt durch eine Flüssigkeitsbremse, wie sie in einem Eisenbahnpuffer eingebaut werden könnte.Fig.r of the drawing is a longitudinal section through a fluid brake as shown in a railway buffer could be installed.

Abb. 2 ist ein Querschnitt nach der Ebene A-A der Abb. 1 in Richtung nach links gesehen.Fig. 2 is a cross-section on the plane AA of Fig. 1 looking towards the left.

Abb. 3 ist ein Querschnitt nach der Ebene B-B der Abb. 1, jedoch entgegengesetzt wie Abb. 2 gesehen.Fig. 3 is a cross section according to the plane BB of Fig. 1, but seen opposite to Fig. 2.

Die Flüssigkeitsbremse besteht aus dem Zylindergehäuse a, dem Deckel b, dem KoI-fcenkörper c, den Regulierfedern d, e, der Druckplatte/, dem Kolben und der Kolbenstange g, der Rückholfeder h, der Manschette i und der Kopfplatte k. The fluid brake consists of the cylinder housing a, the cover b, the piston body c, the regulating springs d, e, the pressure plate /, the piston and piston rod g, the return spring h, the sleeve i and the head plate k.

Tritt der Kolben g infolge Druckes auf die Kopfplatte k in die vom Zylinder a, Kolben g, Druckplatte f und Ringfeder e begrenzte Druckkammer / ein, so entweicht die darin enthaltene Flüssigkeit durch den zwischen dem Kolben g und der Ringfeder e vorhandenen, je nach Druck veränderlichen Schlitz. Die Flüssigkeit wird weiter durch den zwischen der Kolbenstange g und der Ringfeder d vorhandenen Ringraum und durch die Bohrungen des auf einem Konus der Kolbenstange g befestigten Kolbenkörpers c in die Kammer« gedrückt. Diese ist ein Ringraum um die Kolbenstange g und wird vom Gehäuse α, dem Zylinderdeckel b, dem Kolbenkörper c, der Druckplatte/ und den Ringfedern d, e begrenzt. Durch im Deckel b vorgesehene halbkreisförmigeBohrungen (Abb. 2) setzt sich die Kammer m bis in das Innere der Manschette« fort, die mit ihrem einen Ende durch einen Spannring in einer Ausdrehung der Kolbenstange g befestigt ist, während das andere Ende in gleichfalls starrer Weise am Zylinderdeckel b abgedichtet ist. Die Manschette i ist aus Gummi oder ähnlichen hochelastischen Stoffen gefertigt. Durch das hineingedrückte Wasser dehnt sie sich infolge ihrer elastischen Eigenschaft aus und drängt nach Zurückgehen des Kolbens g, was die Rückholfeder h bewirkt, die Flüssigkeit in die Druckkammer / zurück.If the piston g enters the pressure chamber / delimited by the cylinder a, piston g, pressure plate f and ring spring e as a result of pressure on the head plate k , the liquid contained therein escapes through the one between the piston g and the ring spring e , depending on the pressure changeable slot. The liquid is pressed further through the annular space between the piston rod g and the annular spring d and through the bores of the piston body c fastened on a cone of the piston rod g into the chamber «. This is an annular space around the piston rod g and is delimited by the housing α, the cylinder cover b, the piston body c, the pressure plate / and the annular springs d, e . The chamber m continues through the semicircular bores provided in the cover b (Fig. 2) into the interior of the cuff «, which is fastened at one end by a clamping ring in a recess in the piston rod g , while the other end is likewise rigid is sealed on the cylinder cover b. The cuff i is made of rubber or similar highly elastic materials. As a result of the water being pressed in, it expands as a result of its elastic property and, after the piston g has retreated, which is effected by the return spring h , pushes the liquid back into the pressure chamber /.
