Der Erfindung liegt die Aufgabe zugrunde, ein alternatives Dichtkonzept bereitzustellen, das neben einer guten Abdichtwirkung vom Aufbau her einfacher und kostengünstiger ist. Eine Bearbeitung des Zylinderkopfes soll hierbei weitestgehend entbehrlich sein.Of the Invention is based on the object, an alternative sealing concept provide, in addition to a good sealing effect of the construction easier and cheaper is. An editing of the cylinder head should hereby largely be dispensable.
Diese Aufgabe wird gelöst durch eine Einrichtung zur Abdichtung einzelner im Bereich eines Motorblocks vorgesehener Brennräume einer Brennkraftmaschine, von denen ein jeder Brennraum mit einer Zylinderlaufbuchse ausgerüstet ist, wobei das einem Zylinderkopf zugewandte freie Ende zumindest einzelner der Zylinderlaufbuchsen brennraumseitig über einen umlaufenden Feuersteg verfügt, davon radial beabstandet ein umlaufendes Stopperelement vorgesehen ist, radial zwischen Feuersteg und Stopperelement ein Dichtelement geführt ist, das im Einbauzustand an der im Wesentlichen plan ausgeführten Dichtfläche des Zylinderkopfes anliegt und der Feuersteg mit einem zusätzlichen Dichtkörper belegt ist.These Task is solved by a device for sealing individual in the region of an engine block provided combustion chambers an internal combustion engine, of which each combustion chamber with a Cylinder liner equipped is, wherein the cylinder head facing a free end at least one of the cylinder liners on the combustion chamber side over one revolving flank, radially spaced therefrom provided a circumferential stopper element is, radially between the land and stopper element a sealing element guided is, in the installed state of the substantially flat executed sealing surface of the Cylinder head rests and the top land with an additional Densified body is.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.advantageous Further developments of the subject invention are the dependent claims remove.
Der Querschnitt des Dichtelementes kann unterschiedlichste Konturen aufweisen. Er kann entweder rechteckig oder quadratisch oder nach Art eines C- bzw. T-Profils ausgebildet werden. In jedem Fall soll durch die Nichtbearbeitung des Zylinderkopfes keine feste Verbindung (Führung) zwischen Dichtelement und Zylinderkopf in Analogie zum Stand der Technik herbeigeführt werden.Of the Cross-section of the sealing element can have different contours exhibit. He can be either rectangular or square or after Type of C or T-profile are formed. In any case, should by the non-machining of the cylinder head no firm connection (Guide) between the sealing element and the cylinder head in analogy to the prior art brought become.
Optional kann auf dem Feuersteg ein weiterer Dichtkörper angebracht werden, der primär die Funktion hat, das eigentliche Dichtelement vor zu hohen Temperaturen zu schützen. Dies eröffnet die Möglichkeit, das Dichtelement aus temperatursensitiveren Materialien zu fertigen, die bedarfsweise elastisch sein können. Infolge des in die Zylinderlaufbüchse integrierten Stopperelementes lässt sich auch ein verbesserter Kraftfluss gegenüber dem Stand der Technik erzielen und das resultierende Moment im Bereich der Zylinderlaufbuchse minimieren bzw. ausgleichen.optional can be mounted on the Feuersteg another sealing body, the primary the function has, the actual sealing element from too high temperatures to protect. This opens the possibility, manufacture the sealing element from more temperature-sensitive materials, which can be elastic as needed. As a result of the built-in cylinder liner Stopperelementes leaves also an improved power flow over the prior art can be achieved and minimize the resulting torque in the cylinder liner compensate.
Einem weiteren Gedanken der Erfindung gemäß, besteht die Möglichkeit, das Stopperelement und/oder das Dichtelement mit einem, über den Umfang gesehen, variierenden Höhenprofil (Topographie) zu versehen. Ebenfalls denkbar ist, das Stopperelement und/oder das Dichtelement, über den Umfang gesehen, mit einem unterschiedlichen Breitprofil auszugestalten.a according to further ideas of the invention, it is possible the stopper element and / or the sealing element with a, over the Scope seen, varying height profile To provide (topography). It is also conceivable, the stopper element and / or the sealing element, via seen the scope, with a different broad profile to design.
Im Falle der Topographie weist der Umfang des Dichtelementes, respektive des Stopperelementes, nicht überall die gleiche Höhe auf. An den Stellen in der Nähe der Schrauben wird beispielsweise eine niedrigere Höhe gewählt, um diese Bereiche zu entlasten.in the Case of topography, the circumference of the sealing element, respectively the stopper element, not everywhere the same height on. At the places nearby For example, the screws are chosen to be at a lower height to relieve these areas.
Im Falle der Konturierung weist das Dichtelement und/oder das Stopperelement über den Umfang nicht die gleiche Breite auf. An den Stellen in der Nähe der Schrauben wird vorteilhafter Weise eine größere Breite gewählt, um diese Bereiche zu entlasten.in the Trap contouring, the sealing element and / or the stopper element on the Scope does not have the same width. In the places near the screws is advantageously a greater width selected to relieve these areas.
Denkbar ist auch eine Kombination aus Topographie und Konturierung des Dichtelementes und/oder des Stopperelementes. Ziel einer solchen Formgebung des Dichtelementes und/oder des Stopperelementes ist es, die Schraubenkräfte optimal in den Motorblock einzuleiten, um eine möglichst gleichmäßige Flächenpressung im jeweiligen Dichtbereich zu erreichen.Conceivable is also a combination of topography and contouring of the sealing element and / or the stopper element. The aim of such a shaping of the sealing element and / or the stopper element is optimal, the screw forces into the engine block, in order to achieve the most uniform possible surface pressure to achieve in the respective sealing area.
