  Labyrinthpackung für Kolben von Verbrennungskraftmaschinen.

 ausgeschlagen und etwas schmaler geworden sind als die Kolbenringnut, in der sie sitzen. 



   Um diesem Übelstand abzuhelfen, wird die Innenfläche der Kolbenringe unregelmässig ausgebildet und die zugehörige Fläche der Kolbenringnut dementsprechend, so dass, wie aus der Zeichnung hervorgeht, hinter dem Kolbenring eine Labyrinthdichtung entsteht. 



   In der Zeichnung ist in Fig. i ein einseitiger Schnitt durch einen mit drei Kolbenringen versehenen Kolbenkörper, in Fig. 2 ein Schnitt durch den Kolbenring mit Ansicht der Stossfuge und in Fig. 3 eine Draufsicht des Kolbenringes dargestellt. a ist der Kolbenkörper, b der Kolbenring. An der Innenfläche des Kolbenringes ist die Nut   b1   vorgesehen, die exzentrisch sein kann, um die bekannte gleichmässige Federung zu erzielen, obgleich der Kolbenring selbst konzentrisch ist. In der Kolbenringnut des Kolbenkörpers bleibt die Rippe al stehen, die in die Nut   b1   des Kolbenringes eingreift.

   Die Labyrinthdichtung braucht nicht genau zu passen ; dadurch, dass die Explosionsgase auf ihrem Weg von der oberen Kolbenringfläche zur unteren Kolbenringfläche sechsmal um den Vorsprung herumstreichen müssen, wird genügend Dichtung erzielt.

 EMI1.1
 knocked out and become a little narrower than the piston ring groove in which they sit.



   In order to remedy this inconvenience, the inner surface of the piston rings is irregular and the associated surface of the piston ring groove is designed accordingly, so that, as can be seen from the drawing, a labyrinth seal is created behind the piston ring.



   In the drawing, FIG. 1 shows a one-sided section through a piston body provided with three piston rings, FIG. 2 shows a section through the piston ring with a view of the butt joint and FIG. 3 shows a top view of the piston ring. a is the piston body, b is the piston ring. On the inner surface of the piston ring, the groove b1 is provided, which can be eccentric in order to achieve the well-known uniform suspension, although the piston ring itself is concentric. The rib al remains in the piston ring groove of the piston body and engages in the groove b1 of the piston ring.

   The labyrinth seal need not fit exactly; in that the explosion gases have to sweep around the projection six times on their way from the upper piston ring surface to the lower piston ring surface, sufficient sealing is achieved.
