Patentanspruch:Claim: Zylinderlaufbüchse in einem Zylinderblock einer Brennkraftmaschine, insbesondere einer Dieselmaschine, die einen Bund aufweist, der in einer dem Bund angepaßten Ausnehmung des Zylinderblockes liegt und der durch Anordnung einer nach seiner zylindrischen Mantelfläche hin offenen Ringnut in axialer Richtung in sich federnd ausgebildet ist, dadurch gekennzeichnet, daß die Tiefe der Ringnut (5) etwa der Tiefe des Bundes (3) in radialer Richtung entspricht, die Ringnut mit Bezug auf die Höhe des Bundes in dessen oberen Hälfte angeordnet ist und die Breite der Ringnut etwa der Höhe des durch die Ringnut gebildeten oberen Teiles des Bundes entsprichtCylinder liner in a cylinder block of an internal combustion engine, in particular a diesel engine, which has a collar in a recess of the cylinder block that is adapted to the collar is and by the arrangement of an annular groove open towards its cylindrical outer surface in axial direction is resilient in itself, characterized in that the depth of the Annular groove (5) corresponds approximately to the depth of the collar (3) in the radial direction, the annular groove with respect to the Height of the federal government is arranged in the upper half and the width of the annular groove is approximately the height of the corresponds to the upper part of the collar formed by the annular groove liegt in einer Ausnehmung 4 am Zylinderblock 1.lies in a recess 4 on the cylinder block 1. Um dem Bund 3 eine federnde Eigenschaft zu geben, ist eine Ringnut 5 vorgesehen, die nach der Mantelfläche 6 des Bundes 3 hin offen ist Die Tiefe der Ringnut 5 entspricht etwa der Tiefe des Bundes 3 in radialer Richtung. Der Nutengrund 7 ist gerundet ausgebildet Mit Bezug auf die Höhe des Bundes 3 ist die Ringnut 5 in der oberen Hälfte des Bundes angeordnet Die Breite 8 der Ringnut 5 entspricht etwa der Höhe 9 des durch die Ringnut gebildeten oberen Teiles 10 des Bundes 3.In order to give the collar 3 a resilient property, an annular groove 5 is provided which follows the lateral surface 6 of the collar 3 is open. The depth of the annular groove 5 corresponds approximately to the depth of the collar 3 in the radial direction. The groove base 7 is rounded. With reference to the height of the collar 3, the annular groove 5 is in the Upper half of the collar arranged The width 8 of the annular groove 5 corresponds approximately to the height 9 of the through Annular groove formed upper part 10 of the collar 3. Hierzu 1 Blatt Zeichnungen1 sheet of drawings Die Erfindung bezieht sich auf eine Zylinderlaufbüchse in einem Zylinderblock einer Brennkraftmaschine, insbesondere einer Dieselmaschine, die einen Bund aufweist, der in einer dem Bund angepaßten Ausnehmung des Zylinderblockes liegt und der durch Anordnung einer nach seiner zylindrischen Mantelfläche hin offenen Ringnut in axialer Richtung in sich federnd ausgebildet ist.The invention relates to a cylinder liner in a cylinder block of an internal combustion engine, in particular a diesel engine, which has a collar, which lies in a recess of the cylinder block adapted to the collar and which is arranged by a after its cylindrical outer surface open towards the annular groove in the axial direction resilient in itself is. Durch die DE-OS 21 11480 und durch die DE-OS 22 54 221 sind Zylinderlaufbüchsen bekanntgeworden, bei denen der Bund von einer zylindrischen Mantelfläche ausgehend im Bereich der Auflagefläche des Bundes in der Ausnehmung des Zylinderbiockes mit einer Nut versehen ist Diese Nut ist wenig tief ausgebildet, da sie lediglich die Aufgabe hat, durch elastisches Nachgeben der Randzone des Bundes zu örtlichen Spannungspitzen führende Kantenpressungen im Bereich der Auflagefläche zu vermeiden. Bei einer Zylinderlaufbüchse gemäß der DE-PS 12 60 863 ist ferner noch bekannt, am Bund eine senkrecht zur Auflagefläche angeordnete Nut vorzusehen, um Kragenrisse zu vermeiden.Cylinder liners have become known through DE-OS 21 11480 and DE-OS 22 54 221, in which the federal government starts from a cylindrical jacket surface in the area of the bearing surface of the federal government is provided with a groove in the recess of the cylinder block. This groove is not very deep because it only has the task of elastically yielding the edge zone of the federal government to local stress peaks to avoid leading edge pressures in the area of the support surface. For a cylinder liner according to DE-PS 12 60 863 is also known to provide a groove perpendicular to the support surface on the collar, to avoid tears in the collar. Der Erfindung liegt die Aufgabe zugrunde, den oberen Bereich des Bundes in sich federnd auszubilden, damit zur Abdichtung einfache, nicht federnd ausgebildete Dichtringe verwendet werden können und trotz Anordnung solcher Dichtringe vom festgeschraubten Zylinderkopf keine, einen Verzug der Zylinderlaufbüchse verursachende Drücke ausgeübt werden können.The invention is based on the object of making the upper region of the collar resilient in itself, so that simple, non-resilient sealing rings can be used for sealing and despite the arrangement No such sealing rings from the screwed-on cylinder head, a distortion of the cylinder liner causing pressures can be exerted. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Tiefe der Ringnut etwa der Tiefe des Bundes in radialer Richtung entspricht, die Ringnut mit Bezug auf die Höhe des Bundes in dessen oberen Hälfte angeordnet ist und die Breite der Ringnut etwa das durch die Ringnut gebildeten oberen Teiles des Bundes entspricht.This object is achieved in that the depth of the annular groove is approximately the depth of the collar in corresponds to the radial direction, the annular groove arranged with respect to the height of the collar in its upper half and the width of the annular groove corresponds approximately to the upper part of the collar formed by the annular groove. Durch die Erfindung wird erreicht, daß ständig ein Kontakt zwischen der Zylinderlaufbüchse und dem Zylinderkopf vorhanden ist. Drücke, die sich auf die Formbeständigkeit der Zylinderlaufbüchse schädlich auswirken könnten, werden vermieden. Durch eine Änderung der Abmessungen der Ringnut läßt sich leicht eine Anpassung an unterschiedliche Erfordernisse erzielen.The invention ensures that there is constant contact between the cylinder liner and the cylinder head is available. Pressures that have a detrimental effect on the dimensional stability of the cylinder liner could be avoided. An adjustment can easily be made by changing the dimensions of the annular groove to achieve different requirements. In der Zeichnung ist stark vergrößert ein Schnitt durch eine erfindungsgemäße Zylinderlaufbüchse dargestellt. In the drawing, a section through a cylinder liner according to the invention is shown on a greatly enlarged scale. In einem Zylinderblock 1 einer Brennkraftmaschine ist eine Zylinderlaufbüchse 2 eingesetzt. Ein am oberen Ende der Zylinderlaufbüchse 2 angeordneter Bund 3A cylinder liner 2 is used in a cylinder block 1 of an internal combustion engine. One at the top End of the cylinder liner 2 arranged collar 3
