Description
den schwingenden Flanschflächen des Zylinderkopfes bzw. Motorblockes einer Brennkraftmaschine noch mit dem Stützkörper noch mit sich selbst in Be-Führung kommen, d.h. also, vollkommen frei im Dichtspalt schwingen können. Mit zunehmender Entfernuna der gekrümmten Verbindungsstelle von den unterstützten, an den Flanschflächen anliegenden parallelen Schenkelbereichen schwächt sich der Einfluß der Schwingbeweaungen, insbesondere der schwingenden Winkelbewegungen der Flanschflächen. auf die besonders gefährdeten Übergangsstellen von den parallelen Schenkelbereichen zu den einander sich stetig nähernden Schenkelbereichen des Hüllkörpers ab. Damit wird «He Dauerschwingbelastbarkeit des Hüllkörpers beträchtlich erhöht.the vibrating flange surfaces of the cylinder head or engine block of an internal combustion engine can still be guided by oneself with the support body, i.e., completely free in the Sealing gap can oscillate. With increasing distance of the curved junction from the supported parallel leg areas resting on the flange surfaces, the influence is weakened the oscillation movements, especially the oscillating angular movements of the flange surfaces. to the particularly endangered crossing points from the parallel leg areas to the steadily approaching leg areas of the Enveloping body. This means that «He is fatigue life of the enveloping body increased considerably.
Die direkte Verwendung der durch das deutsche Gebrauchsmuster 1 927 873 vorbekannten Rohrflanschdichtung zum Abdichten von Zylinderköpfen bei Brennkraftmaschinen war nicht möglich, da die weit nach innen gezogene Schweißnase infolge der relativ großen Materialanhäufung zu Glühzündungen sowie zu Eigenschwingungen des inneren Hüllkörperbereiches neigt. Außerdem liegt dem Gebrauchsmuster eine vollständig andere Aufgabe zugrunde, so daß die Verwendung einer ähnlichen Dichtung zur Vermeidung von Dauerschwingungsbrüchen bei Brennkraftmaschinen für den Fachmann nicht ableitbar ist. Schließlich wird erst eine die nunmehr gestellte Aufgabe lösende Dichtung dadurch geschaffen, indem die Verbindungsstelle der beiden ichenkel von einem gekrümmten Abschnitt gebildet ist, was zu einer gleichmäßigen thermischen und mechanischen Belastbarkeit des Hüllkörpers führt.The direct use of the pipe flange seal previously known from the German utility model 1 927 873 for sealing cylinder heads in internal combustion engines was not possible because the Welding nose drawn far inwards due to the relatively large accumulation of material leading to glow ignitions as well as tending to natural vibrations of the inner enveloping body area. In addition, there is the utility model a completely different task, so the use of a similar seal to the Avoidance of continuous oscillation breaks in internal combustion engines cannot be derived for a person skilled in the art is. After all, a seal that solves the problem now set is only created by in that the connection point of the two legs is formed by a curved section, which leads to a uniform thermal and mechanical load-bearing capacity of the enveloping body.
Bei den bisher üblichen Ausführungen von Zylinderkopfdichtungen erstreckt sich entweder die Dichtungsplatte als Stützkörper bis in den Krümmun2sbereich des Hüllkörpers, zumindest so weit, daß \λ verspannten Zustand der Hüllkörper vollständig gefüllt ist, oder es sind zusätzliche federnde oder steife Stützkörper in den Hüllkörper nahe des Krümmungsbereiches eingelegt, um am innersten Rand des Hüllkörpers im Bereich der Verbindungsstelle beider Hüllkörperschenkel eine Zone höchster Dichtpressung zu erzielen. Im Gegensatz hierzu lehrt die Erfinduni, die Zone höchster Pressung auf den äußeren Rand des Hüllkörpers zu verlagern und den Innenrand des Hüllkörpers vollkommen pressungs- und berührungsfrei zu halten.In the usual embodiments of cylinder head gaskets, either the sealing plate of the envelope extends as a supporting body until the Krümmun 2 sbereich, at least so far that \ λ strained state of the enveloping body is completely filled, or there are additional resilient or rigid support body in the casing body near of the curvature area in order to achieve a zone of highest sealing pressure at the innermost edge of the enveloping body in the area of the connection point of the two enveloping body legs. In contrast to this, the invention teaches shifting the zone of highest pressure to the outer edge of the enveloping body and keeping the inner edge of the enveloping body completely free of pressure and contact.
Die Erfindung läßt sich in gleicher Weise bei plattenförmigen und ringförmigen Dichtungen anwen-The invention can be used in the same way with plate-shaped and ring-shaped seals.

The encompassing use of other materials for the enveloping body. Furthermore, with the type described above or other material thicknesses, it is not known from the German Utility Model 45 for economic reasons of seals and in particular for spatial reasons, additionally support or spring possible because the thickness of the seal in the braced Zurungskörper between the two legs of the stand is often only 1 to 2 mm. It must be arranged in the shell, so that the elasticity can be found after a solution, whereby the ability of the sealing edge to increase. The influence of the oscillating flange movements on the same also applies to individual sealing rings, which are only made up of the areas at risk of breakage of the enveloping body and the U- or C-shaped enveloping body with a single one, so that resilient support bodies subject to permanent vibration are made to break off no longer occur on the enveloping body,

The support body is encompassed under the Ausnutlele leg and, from the point of elastic deformability of the seal, the support body edge is achieved up to its connection, so that these steadily approach each other with a certain sealing pressure point, and are in contact with the flange surfaces in the case of an internal combustion engine. The reduction in the gasket strength to prevent fatigue vibrations inevitably means using a surface of the enveloping body, the reduction in the distance between the two legs being connected by a curved section supported legs and the radius of curvature being connected to the other.
