Description

Kolbenabdichtung bei doppelt wirkenden Kolbenkraftmaschinen Bei Kolbenkraftmaschinen ist es bekannt, einen Kolben ohne Kolbenring zu verwenden und die Dichtung in die Zylinderwandung zu verlegen. Auch ist es bei doppelt wirkenden Kolbenkraftmaschinen bekannt, die Dichtungsringe in der Zylindermitte vorzusehen. Zur einwandfreien Führung der Kolbenstange muß jedoch in allen diesen Fällen die Kolbenstange an beiden Zylinderenden durch ein besonderes Lager getragen werden, so daß dabei zwei nach außen hin liegende Stopfbüchsendichtungen Anwendung finden müssen.Piston sealing in double-acting piston engines. In piston engines it is known to use a piston without a piston ring and the seal in the To lay the cylinder wall. It is also the case with double-acting piston engines known to provide the sealing rings in the middle of the cylinder. For flawless leadership In all these cases, however, the piston rod must have the piston rod at both cylinder ends be carried by a special bearing, so that there are two outwardly lying Stuffing box seals must be used.

Die Erfindung erreicht nun eine einfachere Anordnung einer Kolbenkraftmaschine mit an der Zylinderwandung vorgesehenen selbstdichtenden Ringen, in dem sie die Gehäuse, welche die selbstfedernden Dichtungsringe aufnehmen, zwischen den Teilen einer dreiteiligen Zylinderbüchse einklemmt, von denen der mittlere Teil tragend wirkt.The invention now achieves a simpler arrangement of a piston engine with provided on the cylinder wall self-sealing rings in which they the Housing, which accommodate the self-resilient sealing rings, between the parts a three-part cylinder liner, of which the middle part is bearing works.

In der Zeichnung ist als Beispiel ein derart ausgeführter Dampfmaschinenzylinder imLängsschnitt dargestellt, und zwar bei Gleichstromanordnung, doch kann die Ausbildung sinngemäß auch für Wechselstromdampfmaschinenzylinder oder auch bei einseitig wirkenden Kolben von Verbrennungskraftmaschinen Anwendung finden. Es bezeichnet r den Kolben, 2 die Kolbenstange, 3 die Kolbendichtung und q. die Wandung des Zylinders, in deren aus Kammern gebildeten Nuten 5 die Dichtungsringe 6 untergebracht sind, so daß das Schmieröl vermittels der Löcher 7 leicht von außen zugeführt werden kann und der Kolben x nur eine glatte Wandung braucht. Um bei den in Frage kommenden hohen Drücken die Reibung zwischen Kolben und den Dichtungsringen auf ein Mindestmaß zu beschränken, sind beide Teile aus verschiedenen Metallen gebildet, die den geringsten Verschleiß ergeben, z. B. der Kolben aus Chromnickelstahl und die Dichtungsringe aus Bronze oder beide aus ähnlichen in gleicher Weise passend zusammenarbeitenden Metallen.The drawing shows a steam engine cylinder designed in this way as an example shown in longitudinal section, with a direct current arrangement, but the training correspondingly also for AC steam engine cylinders or also for one-sided acting Find pistons of internal combustion engines application. It denotes the piston, 2 the piston rod, 3 the piston seal and q. the wall of the cylinder, in whose Grooves 5 formed from chambers, the sealing rings 6 are accommodated so that the Lubricating oil can easily be supplied from the outside by means of the holes 7 and the Piston x only needs a smooth wall. To at the high pressures in question to limit the friction between the piston and the sealing rings to a minimum, Both parts are made of different metals that have the least amount of wear and tear result, e.g. B. the piston made of chrome nickel steel and the sealing rings made of bronze or both of similar equally mating metals.
