Abstract

The seal for the cylinder head consists essentially of an elastomer ring of U section which is placed in an annular groove cut in the top of e.g. a cylinder lining. The ring is placed with the webs of the U pointing radially outward. The bottom web lies flat on the flat bottom of the groove while the top web points upwards at a slight angle and lies with its edge against the cylinder head. The outside edge of this web protrudes by a small amount above the annular groove. The top face of this web forms part of an inverted cone, the tip of which lies on the centreline of the cylinder.

Description

Zylinderkopfdichtung für Brennkraftmaschinen Die Erfindung bezieht sich auf eine Zylinderkopfdichtung für Brennkraftmaschine, die im wesentlichen aus einem elastischen Dichtring besteht, der zwischen zwei ebenen Flächen, insbesondere zwischen einer ebenen Fläche des Zylinderkopfes und einer Ausnehmung in einem Bund einer in den Zylinderblock eingesetzten Laufbuchse, angeordnet ist. Cylinder head gasket for internal combustion engines The invention relates on a cylinder head gasket for internal combustion engines, which essentially consists of consists of an elastic sealing ring between two flat surfaces, in particular between a flat surface of the cylinder head and a recess in a collar a liner inserted into the cylinder block.

Der Erfindung liegt die Aufgabe zugrunde, einen Dichtring dieser Art so auszubilden, daß die vom festgeschraubten Zylinderkopf auf die Laufbüchse ausgeübten Drücke durch den Dichtring ohne Beeinträchtigung der Dichtfunktion so elastisch übertragen werden, daß ein Verzug der Laufbüchse nicht auftreten kann.The invention is based on the object of a sealing ring of this type to be trained so that the exerted from the bolted cylinder head on the liner Press through the sealing ring so flexibly without impairing the sealing function be transferred so that a delay of the liner can not occur.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Dicht ring im Querschnitt etwa U-förmig mit einem radial innenliegenden Steg und radial nach außen weisenden Schenkeln ausgebildet ist und der eine Schenkel flach auf der einen ebenen Pläche, z.B. auf dem Bund der Laufbüchse, der andere lediglich mit einer radial äußeren Kante an der anderen ebenen Fläche, z.B. am Zylinderkopf, anliegt.The object is achieved according to the invention in that the Sealing ring in cross section approximately U-shaped with a radially inner ridge and radially outwardly pointing legs is formed and one leg is flat on one flat surface, e.g. on the collar of the liner, the other only with a radially outer edge on the other flat surface, e.g. on the cylinder head, is present.

Durch die Erfindung wird ein elastischer Dichtring erzielt, der eine hervorragende Gasabdichtung bewirkt und mit dem die Laufbüchse im Zylinderblock derart gehalten wird, daß Verzüge der Laufbüchse nicht auftreten.By the invention, an elastic sealing ring is achieved, the one causes excellent gas sealing and with which the liner in the cylinder block is held in such a way that distortions of the liner do not occur.

In Ausgestaltung des Erfindungsgegenstandes kann der mit der äußeren Kante versehene Schenkel eine äußere Fläche aufweisen, die als Teil einer Kegelmantelfläche eines Kegels ausgebildet ist, dessen Spitze in der Mittellängsachse durch den Dichtring liegt.In an embodiment of the subject matter of the invention, the one with the outer Edge provided legs have an outer surface as part of a conical surface a cone is formed, the tip of which in the central longitudinal axis through the sealing ring lies.

In der Zeichnung ist ein erfindungsgemäßer Dichtring in einem Ausführungsbeispiel dargestellt.In the drawing, a sealing ring according to the invention is in one embodiment shown.

Eine in einen Zylinderblock 1 eingesetzte Laufbüchse 2 einer Brennkraftmaschine ist mit einem Bund 3 versehen, der eine Ausnehmung 4 aufweist. In der Ausnehmung 4 liegt ein im Querschnitt etwa U-förmig ausgebildeter Dichtring 5, der bei festgeschraubtem Zylinderkopf 6 in Verbindung mit einer Flachdichtung 7 die Brennkraftmaschine abdichtet.A liner 2 of an internal combustion engine inserted into a cylinder block 1 is provided with a collar 3 which has a recess 4. In the recess 4 there is a sealing ring 5 which is approximately U-shaped in cross section and which is screwed tightly Cylinder head 6 in conjunction with a flat gasket 7 seals the internal combustion engine.

Der Dichtring 5 zeigt einen radial innenliegenden Steg 8 und zwei radial nach außen weisende Schenkel 9, 10. Der Schenkel 9 liegt mit seiner unteren Ringfläche flach auf dem Bund 3, an.The sealing ring 5 shows a radially inner web 8 and two radially outwardly pointing legs 9, 10. The leg 9 lies with its lower Ring surface flat on the collar 3.

Der Schenkel 10 dagegen zeigt eine dem Zylinderkopf 6 zugekehrte Fläche 11, die als Teil einer Kegelmantelfläche eines Kegels ausgebildet ist, dessen Spitze in der Mittellängsachse durch den Dichtring liegt, derart, daß die äußere Kante 12 der Fläche 11 gegen den Zylinderkopf 6 vorsteht.The leg 10, on the other hand, shows a surface facing the cylinder head 6 11, which is designed as part of a conical surface of a cone, the tip of which lies in the central longitudinal axis through the sealing ring, in such a way that the outer edge 12 of the surface 11 protrudes against the cylinder head 6.

Je nach Ausbildung der Nuten 13 zwischen den beiden Schenkeln 9, 10 des Dichtringes 5 ist es möglich, dem Dicht ring eine größere oder kleiner Elastizität zu geben. Eine genaue Abstimmung auf die vom Zylinderkopf ausgeübten Drücke ist erzielbar. Es ist auch möglich, den Dichtring 5 nach einer Demontage des Zylinderkopfes erneut zu verwenden.Depending on the design of the grooves 13 between the two legs 9, 10 of the sealing ring 5, it is possible to give the sealing ring a greater or lesser elasticity admit. An exact match to the pressures exerted by the cylinder head is achievable. It is also possible to remove the sealing ring 5 after dismantling the cylinder head to use again.
