Abstract
Description
Die Erfindung betrifft eine Einrichtung zur Abdichtung einzelner im Bereich eines Motorblocks vergesehener Brennräume einer Brennkraftmaschine.The The invention relates to a device for sealing individual in Area of an engine block foreseen combustion chambers of a Internal combustion engine.

Der Erfindung liegt die Aufgabe zugrunde, ein alternatives Dichtkonzept vorzuschlagen, das einfach im Aufbau ist und mit einer Vielzahl unterschiedlichster Dichtelemente realisiert werden kann.Of the Invention is based on the object, an alternative sealing concept To propose that is simple in construction and with a variety Different sealing elements can be realized.
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 freie Ende der jeweiligen Zylinderlaufbuchse mit einem umlaufenden Kragen und ein Zylinderkopf zylinderlaufbuchsenseitig mit einem umlaufenden Ansatz versehen ist, wobei Kragen und Ansatz einen vorgebbaren radialen Abstand zueinander aufweisen und radial zwischen Kragen und Ansatz mindestens ein Dichtelement positioniert ist.These The object is achieved by a device for sealing individual combustion chambers provided in the region of an engine block an internal combustion engine, of which each combustion chamber with a Cylinder liner is equipped, with the free end the respective cylinder liner with a circumferential collar and a cylinder head cylinder liner side with a circumferential Approach is provided, wherein the collar and approach a predetermined radial Distance apart and radially between the collar and approach at least one sealing element is positioned.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.advantageous Further developments of the subject invention are the dependent claims refer to.
Gegenüber dem Stand der Technik wird nun kein axiales, vielmehr ein radiales Dichtkonzept zur Verfügung gestellt, das an jeder einzelnen Zylinderlaufbuchse vorgesehen wird.Across from The prior art is now no axial, but a radial Sealing concept provided to each individual Cylinder liner is provided.
Durch unterschiedliche Ausbildungen des Kragens an der Zylinderlaufbuchse und der Form der Auflagerfläche, teilweise in Kombination mit einem elastischen Dichtkörper, kann die Zylinderkopfbuchse momenten- bzw. kraftfrei bleiben.By different configurations of the collar on the cylinder liner and the shape of the bearing surface, partly in combination With an elastic sealing body, the cylinder head bushing can remain moment or force free.
Das radiale Dichtelement kann im Kraftnebenschluss zwischen Kragen und Ansatz platziert werden, so dass sich auf diese Weise sowohl radiale als auch axiale Bewegungen zwischen Zylinderkopf und Motorblock ausgleichen lassen.The Radial sealing element can be in the force shunt between collar and Be placed so that in this way both radial as Also compensate for axial movements between the cylinder head and engine block to let.
Wie bereits angesprochen, können für das Dichtelement unterschiedlichste Materialien zum Einsatz gelangen. Denkbar wäre beispielsweise ein Blechring mit einer Sicke oder eine Weichstoffdichtung mit Einfassung.As already mentioned, can for the sealing element various materials are used. It would be possible For example, a metal ring with a bead or a soft seal with surround.
Das Dichtelement kann hierbei unterschiedlichste Querschnittsformen aufweisen.The Sealing element can here a variety of cross-sectional shapes exhibit.
Ein radiales Dichtkonzept bietet die Möglichkeit, die Schraubenkräfte drastisch zu reduzieren, da keine Schraubenkraft für das Verspannen des Dichtelements benötigt wird. Zudem ist das Dichtelement unabhängig von der dynamsichen Bewegung im Dichtspalt.One radial sealing concept offers the possibility of screw forces drastically reduce because no screw force for that Bracing the sealing element is needed. Moreover, that is Sealing element independent of dynamic movement in the sealing gap.
Der Erfindungsgegenstand ist anhand eines Ausführungsbeispiels in der Zeichnung dargestellt und wird wie folgt beschrieben. Es zeigen:Of the Subject of the invention is based on an embodiment shown in the drawing and is described as follows. It demonstrate:
