Description

KAISERLICHES /IMPERIAL /

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf eine neue Dichtungsvorrichtung für Kraftmaschinen mit umlaufenden Kolben, durch welche eine zuverlässige Dichtung an der Berührungsstelle zwischen Kolbentrommel bezw. Kolbenwelle und der Zylinderwandung zwischen den Ein- und Auslaßkanälen für das Druckmittel erzielt werden soll. Die Vorrichtung besteht .im wesentlichen aus mehreren Einzeldichtungen, welche in Nuten des Zylinders liegen und, unter Federdruck stehend, außerhalb des Zylinders miteinander verbunden sind.The invention relates to a new sealing device for prime movers with rotating piston, through which a reliable seal at the point of contact between piston drum respectively. Piston shaft and the cylinder wall between the inlet and outlet channels for the pressure medium should be achieved. The device essentially consists of several individual seals, which lie in the grooves of the cylinder and, under spring pressure, are connected to one another outside the cylinder.

Durch diese Verbindung der Dichtungen untereinander wird verhindert, daß eine derselben beim Darüberhingleiten des Kolbens aus der Zylinderwandung hervor- und in die Kolbentrommelnuten eintreten und dadurch beschädigt werden oder Stöße in der Maschine hervorrufen kann.This connection of the seals to one another prevents one of them when sliding over the piston out of the cylinder wall and into the Piston drum grooves enter and become damaged, or shocks in the machine can cause.

Auf der Zeichnung ist die neue Dichtungsvorrichtung in einem Ausführungsbeispiel dargestellt; dabei zeigt:In the drawing, the new sealing device is in one embodiment shown; shows:

Fig. ι einen Querschnitt undFig. Ι a cross section and

Fig. 2 einen Längsschnitt durch die Maschine. 2 shows a longitudinal section through the machine.

Es ist ι der Zylinder der Maschine, in dessen Deckeln 2 die aus der Kolbentrommel 3 und den seitlichen Kraftübertragungsscheiben 4 bestehende Achse mit zwei Wellenstümpfen 5 gelagert ist. Es ist beispielsweise ein Kolben 6 angenommen, der in einer Nut der Kolbentrommel 3 und in entsprechenden Nuten der Scheiben 4 gleitet und durch die letzteren die Kraft auf die Welle überträgt. Die Kolbentrommel 3 ist, exzentrisch im Zylinder gelagert und berührt die Zylinderwandung zwischen den Ein- und Auslaßöffnungen ja, yb für das Druckmittel. An dieser Stelle ist zur Schaffung einer größeren Berührungsfläche zwischen Kolbentrommel und Zylinderwandung letztere konzentrisch zur Trommel 3 gestaltet.It is ι the cylinder of the machine, in whose covers 2 the axis consisting of the piston drum 3 and the lateral power transmission disks 4 is mounted with two stub shafts 5. A piston 6 is assumed, for example, which slides in a groove in the piston drum 3 and in corresponding grooves in the disks 4 and through the latter transmits the force to the shaft. The piston drum 3 is mounted eccentrically in the cylinder and touches the cylinder wall between the inlet and outlet openings j a , y b for the pressure medium. At this point, in order to create a larger contact area between the piston drum and the cylinder wall, the latter is designed concentrically to the drum 3.

Zur Abdichtung dieser Stelle sind mehrere, zweckmäßig drei Dichtungsstreifen oder Leisten 8 benutzt, die in parallelen Nuten des Zylinders 1 liegen und durch Federn 9 gegen die Kolbentrommel 3 gepreßt werden. In jeder Dichtungleiste 8 sind zwei Stäbe 10 befestigt, die durch Bohrungen des Zylinders nach außen ragen. Außerhalb des Zylinders sind je drei an einer Seite liegende Stäbe 10 durch je einen Querstab II miteinander verbunden. Durch diese Verbindung der drei Dichtungsstreifen untereinander wird verhindert, daß beim Darüberhingleiten des KoI-bens, oder wenn der Kolben gerade über einer Dichtung steht (Fig. 1), diese durch die Federn 9 aus ihrer Zylindernut heraus- und in die Kolbentrommelnut hineingedrückt wird, da sie durch die beiden anderen an der Kolbentrommel 3 anliegenden Streifen 8 in ihrer Lage gehalten wird.To seal this point, several, expediently three sealing strips or Bars 8 used, which lie in parallel grooves of the cylinder 1 and by springs 9 against the piston drum 3 are pressed. In each sealing strip 8 there are two rods 10 attached, which protrude through holes in the cylinder to the outside. Outside the cylinder three rods 10 lying on one side are connected to one another by a cross rod II each. This connection between the three sealing strips prevents that when the piston glides over it, or when the piston is just about a seal is available (Fig. 1), this out through the springs 9 from their cylinder groove and is pressed into the piston drum groove, as it is through the other two on the Piston drum 3 adjacent strips 8 is held in place.
