In das Gehäuse einer Brennkraftmaschine eingesetzteUsed in the housing of an internal combustion engine
Zylinderbüchse.Cylinder liner.
Die Erfindung betrifft eine in das Gehäuse einer Brennkraftmaschine eingesetzte Zylinderbüchse mit wenigstens einer in einer in der Sitzfläche der Zylinderbüchse oder des Gehäuses vorgesehenen Ringnut angeordneten Ringdichtung.The invention relates to a device in the housing of an internal combustion engine inserted cylinder liner with at least one in one in the seat of the cylinder liner or the housing provided annular groove arranged ring seal.
Es ist bekannt, daß in den Ringspalt zwischen der Sitzfläche der Zylinderbüchse und der des Gehäuses bei seitlicher Bewegung der Zylinderbüchse Öl angesaugt und anschließend stark komprimiert wird. Dabei treten im Spalt sehr hohe Drücke auf, die in Verbindung mit der Temperatureinwirkung zum Zerfall des Öles in stark korrosiv wirkende Bestandteile führen. Versuche, derartigen, durch Eindringen von Kühlwasser in den Spalt bedingten Kavitationserscheinüngen entgegenzuwirken, indem der dem Kühlwasserraum zugewandte Teil der Sitzfläche der Zylinderbüchse bis zum Ringnut für den kühlwasserseitigen Dichtungsring durch Ausnehmungen derart geschwächt wird, daß die Sitzfläche nur noch mit über ihren Umfang verteilte Rippen an der Sitzfläche des Gehäuses anliegt, haben zu keinem befriedigenden Ergebnis geführt, weil dadurch der Sitz der Zylinderbüchse im Gehäuse 9098 10/0538It is known that in the annular gap between the seat the cylinder liner and that of the housing at the side Movement of the cylinder liner oil is sucked in and then strongly compressed. Very high levels occur in the gap Press on that in connection with the temperature exposure to break down the oil into strongly corrosive components to lead. Attempts to find such cavitation phenomena caused by the penetration of cooling water into the gap counteract this by the part of the seat surface of the cylinder liner facing the cooling water space up to the annular groove for the sealing ring on the cooling water side is weakened by recesses so that the seat only with Ribs distributed over its circumference bear against the seat surface of the housing, do not lead to a satisfactory result out, because this causes the seat of the cylinder liner in the housing 9098 10/0538
geschwächt und außerdem die Dichtwirkung des Dichtungsringes verringert wird, da dieser aus seiner Nut in die Ausnehmungen gequetscht wird.weakened and also the sealing effect of the sealing ring is reduced, since this out of its groove in the Recesses is squeezed.
Die Erfindung besteht darin, daß wenigstens eine der Sitzflächen im Bereich zwischen der Ringdichtung und dem Innenraum des Gehäuses durch im Abstand voneinander angeordnete offene Ringnuten unterbrochen sind. Die Unterbrechung einer der Sitzflächen, zwischen denen bei Spalterweiterung die Pumpenwirkung und bei der anschließenden Spaltvei-engung die hohe Kompression des Öles stattfindet, durch die Ringnuten hat zur Folge, daß sowohl bei der Spalterweiterung die Saugwirkung als auch bei der Spaltverengung das Entstehen hoher Öldrücke weitgehend vermieden wird. Bei der Sp alt verringerung kann das im Spalt eingeschlossene öl in diese Ringnuten, die offen sind und daher keinen Dichtungsring enthalten, entweichen.The invention consists in that at least one of the seat surfaces in the area between the ring seal and the Interior of the housing are interrupted by spaced apart open annular grooves. The interruption one of the seats, between which the pumping action when the gap is widened and the subsequent one Gap narrowing the high compression of the oil takes place, The result of the annular grooves is that both when the gap is widened the suction effect as well as when the gap is narrowing the development of high oil pressures is largely avoided. With the gap reduction, the trapped in the gap can oil can escape into these ring grooves, which are open and therefore do not contain a sealing ring.
Die Ringnuten bilden vorteilhaft Windungen einer Schraubenlinie, so daß in ihnen sich sammelndes öl nach unten herauslaufen kann.The annular grooves advantageously form turns of a helical line, so that oil that collects in them runs out downwards can.
In der Zeichnung ist der Gegenstand der,Erfindung beispielsweise und schematisch dargestellt. Es zeigen:In the drawing, the subject of the invention is for example and shown schematically. Show it:

Fig. 1 einen senkrechten Schnitt durch den Sitz einer Zylinderbuchse im Gehäuse,Fig. 1 is a vertical section through the seat of a Cylinder liner in housing,
Fig. 2 einen Ausschnitt aus Fig. 2 im vergrößerten Maßstab .FIG. 2 shows a detail from FIG. 2 on an enlarged scale .
Eine Zylinderbüchse 1 ist mit einem Außenbund 2 versehen, mit dem die Zylinderbüchse 1 in ein Motorgehäuse 3 eingepreßt ist. Zwischen der Sitzfläche 2a der Zylinderbüchse Λ und der Sitzfläche 3a des Motorgehäuses befindet sich ein Spalt, der unten mit einem mit dem Kurbelgehäuse in Verbindung stehenden freien Raum 4· mündet.A cylinder liner 1 is provided with an outer collar 2 with which the cylinder liner 1 is pressed into a motor housing 3. Between the seat surface 2a of the cylinder liner Λ and the seat surface 3a of the engine housing there is a gap which opens at the bottom with a free space 4 in communication with the crankcase.
Der sich über die Höhe h erstreckende Spalt des Sitzes der Zylinderbüchse 1 ist durch einen Dichtungsring 8 unterbrochen, der in eine Dichtungsnut 7 eingelassen ist, die in die Sitzfläche 2a der Zylinderbüchse eingearbeitet ist.The gap of the seat of the cylinder liner 1 extending over the height h is interrupted by a sealing ring 8, which is let into a sealing groove 7 which is incorporated into the seat surface 2a of the cylinder liner.
Der unterhalb des Dichtungsringes 8 liegende Teil der Sitzfläche 2a ist durch Eingnuten 10 unterbrochen, die sich um den gesamten Umfang der Sitzfläche 2a erstrecken.The part of the underneath the sealing ring 8 Seat 2a is interrupted by grooves 10, which extend around the entire circumference of the seat surface 2a.
Die Eingnuten 10 können auch Windungen einer Schraubenlinie bilden, so daß sich in ihnen sammelndes öl nach unten in den Raum 4 ablaufen kann.The grooves 10 can also be turns of a helix form, so that in them collecting oil downwards can run into room 4.
Die Eingnuten können statt in der Sitzfläche 2a der Zylin-The grooves can instead of the seat 2a of the cylinder

derbüchse auch in der Sitzfläche 3a des Gehäuses vorgesehen sein. derbüchse can also be provided in the seat 3a of the housing.
Erweitert sich zufolge seitlich auf die Zylinderbüchse 1 wirkender Drücke der Spalt zwischen den Sitzflächen 2a und 3a, so wird aus dem Raum 4 öl in den Spalt gesaugt und bei Verringerung des Spaltes unter hohen Druck gesetzt. Durch die Ringnuten 10 wird sowohl die Saugwirkung als auch die Druckwirkung verringert. Bei der Spaltverminderung kann das angesaugte öl in die Ringnuten entweichen, so daß das öl nur noch geringen Drücken ausgesetzt ist.According to it, it expands laterally to the cylinder liner 1 acting pressures of the gap between the seat surfaces 2a and 3a, oil is sucked into the gap from space 4 and placed under high pressure when the gap is reduced. Through the annular grooves 10, both the suction and the pressure effect is reduced. When the gap is narrowed, the sucked in oil can escape into the ring grooves, so that the oil is only exposed to low pressures.
