Description

DEUTSCHESGERMAN

Die Erfindung betrifft einen Zylinder mit Zylinderkopf für Kolbenmaschinen, insbesondere Kolbenverbrennungskraftmaschinen, mit einer in der Trennfuge zwischen, den beiden Bauteilen angeordneten Dichtung.The invention relates to a cylinder with a cylinder head for piston engines, in particular piston internal combustion engines, with one arranged in the parting line between the two components Poetry.

Bekanntlich bereitet die Dichtung der Trennfuge zwischen Zylinder und Zylinderkopf bei Kolbenmaschinen, insbesondere Kolbenverbrennungskraftmaschinen, erhebliche Schwierigkeiten. Abgesehen davon, daß das Einlegen der Dichtungen und das Anziehen der Zylinderkopfschrauben mit größter Sorgfalt durchgeführt werden muß und daher eine zeitraubende Tätigkeit darstellt, besteht vor allem bei Brennkraftmaschinen die Gefahr, daß bei nicht vorschriftmäßigem Aufbau des Kopfes die heißen Verbrennungsgase in die Trennfuge eindringen, die Dichtung verbrennen und dann bei jedem Arbeits- und Kompressionshub durchblasen.As is well known, the seal of the parting line between the cylinder and cylinder head in piston engines in particular piston internal combustion engines, considerable difficulties. Apart from this, that the insertion of the seals and the tightening of the cylinder head screws with the greatest care must be carried out and is therefore a time-consuming activity, consists primarily of Internal combustion engines run the risk of the hot combustion gases if the head is not constructed in accordance with the regulations penetrate the parting line, burn the seal and then with each work and Blow through the compression stroke.

Es ist bereits vorgeschlagen worden, bei Verbrennungskraftmaschinen in der Trennfuge zwischen Zylinderkopf und Zylinder eine entweder in die Dichtfläche des Zylinderkopfes oder in die Dichtfläche des Zylinders eingearbeitete, beispielsweise ringförmige Rille vorzusehen, die in einem bestimmten Abstand von der Zylinderbohrung angeordnet ist. Beim Verspannen von Zylinder und Zylinderkopf schmiegt sich die in die Trennfuge eingelegte Dichtung in diese Rille ein, wodurch das Herausdrücken, der Dichtung aus der Trennfuge erschwert wird. Bei dieser bekannten Ausbildung der Dichtung zwischen Zylinderkopf und Zylinder besteht aber immer noch die Gefahr, daß die Dichtung an den Stellen, an denen, sie mit den heißen Verbrennungsgasen in Verbindung steht, verbrennt, so daß der erstrebte Erfolg nicht erzielt werden kann.It has already been proposed in internal combustion engines in the parting line between cylinder head and cylinder either in the sealing surface of the cylinder head or worked into the sealing surface of the cylinder, for example ring-shaped Provide groove which is arranged at a certain distance from the cylinder bore. When bracing of the cylinder and cylinder head, the seal inserted in the parting line nestles into it Groove, which makes it difficult to push the seal out of the joint. With this well-known Formation of the seal between the cylinder head and cylinder but there is still the risk that the seal in the places where they with the hot combustion gases is in connection, burns, so that the desired success is not achieved can be.

Die vorliegende Erfindung bezweckt, die Mängel dieser bekannten Konstruktion zu vermeiden. Sie besteht darin, daß die Rille am inneren Rand der Dichtfuge vorgesehen und die Dichtung in ihrem Innenrand mit einer an sich bekannten, Metallarmierung versehen ist, die sich beim Verspannen von Zylinder und Zylinderkopf in die Rille einschmiegt. Auf diese Weise wird die Dichtung sowohl gegen Verbrennen als auch gegen radiales Hinausdrücken aus der Dichtungsfuge gesichert. Die Rille am Innenrand der Trennfuge kann in der Weise gebildet werden, daß die Zylinderlauffläche an ihrem oberen Rand mit einer stufenförmigen Eindrehung versehen ist oder daß eine entsprechende Nut im Zylinderkopf vorgesehen ist. Auch kann sowohl eine stufenförmige Eindrehung in der Zylinderlauffläche als auch eine entsprechende Eindrehung im Zylinderkopf vorgesehen, sein.The present invention aims to obviate the shortcomings of this known construction. she consists in that the groove is provided on the inner edge of the sealing joint and the seal in its inner edge is provided with a known, metal reinforcement, which is when bracing the cylinder and cylinder head nestles in the groove. This way the seal is both protected against burning and secured against radial pushing out of the sealing joint. The groove on the inside edge of the Parting line can be formed in such a way that the cylinder running surface at its upper edge with a step-shaped recess is provided or that a corresponding groove is provided in the cylinder head. A stepped recess in the cylinder running surface as well as a corresponding one can also be used Notch provided in the cylinder head.

Die im Zylindergehäuse 1 eingehängte Laufbüchse 2 ist an ihrem oberen inneren Rand mit einer stufenr artigen Eindrehung 3 versehen. Der Eindrehung 3 in der Lauf büchse 2 zugeordnet ist im Zylinderkopf 4 eine ringförmige Nut 5 eingedreht. In die Trennfuge zwischen Zylinderkopf und Zylinder ist eine Dichtung 6 aus Kupferasbest eingelegt, die an ihrem inneren Rand mit einer Armierung 7 aus Kupfer versehen ist.The liner 2 suspended in the cylinder housing 1 is at its upper inner edge with a stepped like recess 3 provided. The recess 3 in the liner 2 is assigned in the cylinder head 4 an annular groove 5 is screwed in. There is a seal in the joint between the cylinder head and the cylinder 6 made of copper asbestos, which is provided on its inner edge with a reinforcement 7 made of copper is.

Beim Anziehen der Zylinderkopf schrauben, schmiegt sich das Material der Armierung 7 in die aus der stufenförmigen Eindrehung 3 und der ringartigen Nut 5 gebildete Rille ein und schützt dadurch die eigentliche Dichtungsscheibe vor dem Angriff der heißen Verbrennungsgase.When tightening the cylinder head screw, the material of the reinforcement 7 hugs the from the step-shaped recess 3 and the annular groove 5 formed a groove and thereby protects the actual sealing washer before the attack of the hot combustion gases.
