Abstract

The gasket is intended for engines wherein the cylinder head bolts adjacent the cylinder bore and those near the cam shaft are of different size and require different torques to tighten them. The gasket has cut-outs for the cam shaft drive and for the pistons and cylinder head bolting. The different thicknesses of the gasket when new, compensates. The reduced thickness may be achieved by compression prior to use. There may be a gradual transition between the portions of different thickness. Usually, cylinder gaskets have the same thickness and in mounting a difference in the pressing together results from the different starting torques of the bolts. A strain or distortion results between the dividing surfaces. This strain is usually carried over to the cam shaft and causes a heavier turning moment. The invention prevents this happening.

"Zylinderkopfdichtung""Cylinder head gasket"

Die Erfindung betrifft eine Zylinderkopfdichtung für Ilubkolbenbrennkraftmaschinen mit obenliegender Nockenwelle, für deren Pressung zwischen Zylinderkopf und Zylinderkurbelgehäuse im Bereich der Zylinder und des Nockenwellenantriebs unterschiedlich dimensionierte Zylinderkopfschrauben mit unterschiedlichen Anzugsdrehmomenten verwendet werden, und die einen Ausschnitt für den Durchtritt des Nockenwellenantriebs und Ausschnitte für den Durchtritt der Kolben und der Zylinderkopfschrauben aufweist.The invention relates to a cylinder head gasket for reciprocating piston internal combustion engines with overhead camshaft, for pressing it between cylinder head and cylinder crankcase in the area of the cylinder and the camshaft drive with differently dimensioned cylinder head bolts different tightening torques can be used, and the one cutout for the passage of the camshaft drive and cutouts for the passage of the piston and which has cylinder head bolts.

Bei bekannten Zylinderkopfdichtungen, die eine gleichbleibende Dicke aufweisen, ergibt sich bei der Montage durch die unterschiedlichen Anzugsdrehmomente der Schrauben auch eine unterschiedliche Zusammenpressung der Dichtung und damit ein Verzug der beiden Trennflächen. Dieser Verzug wird auf die Nockenwellenachse übertragen und führt zum schwergängigen Durchdrehen der Nockenwelle.In known cylinder head gaskets that have a constant Have thickness, the different tightening torques of the screws also result in a different compression of the seal and thus a distortion of the two separating surfaces. This delay is on the camshaft axis and leads to the stiff Spin the camshaft.

Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil mit baulich und herstellungsmäßig einfachen Mitteln wirkungsvoll zu vermeiden. ,The invention is based on the object of effectively addressing this disadvantage with structurally and manufacturing-wise simple means to avoid. ,

Die Erfindung besteht darin, daß die. Dichtung im Neuzustand im Bereich der Zylinderbohrungen dicker ist, als im Bereich des Durchtritts für den Nockenwellenantrieb.The invention is that the. Seal in new condition is thicker in the area of the cylinder bores than in the area of the passage for the camshaft drive.

Bei einer vorteilhaften Ausführungsform der Erfindung wird die geringere Dicke der Dichtung durch Vorpressung erreicht.In an advantageous embodiment of the invention, the reduced thickness of the seal is achieved by pre-pressing.

In weiterer Ausgestaltung der Erfindung besteht zwischen beiden Bereichen unterschiedlicher Dicke der Dichtung ein Übergang.In a further embodiment of the invention, there is a seal of different thicknesses between the two areas Crossing.
