Description

Zylinder aus Leichtmetall mit eingesetztem Zylinder aus als Kolbenlauffläche geeignetem Material, insbesondere als Arbeitszylinder für Fahrzeugmotoren, Kompressoren u. dg1. Die vorliegende Erfindung betrifft aus Leichtmetall hergestellte, luftgekühlte Arbeitszylinder, insbesondere für Fahrzeugmotoren, Kompressoren u. dgl., deren; Arbeitsfläche bzw. Kolbenlaufbahn aus einem fest eingefügten Zylinder besteht, der aus einem als Kolbenlauffläche geeignetem Material hergestellt ist.Cylinder made of light metal with an inserted cylinder as a piston running surface suitable material, in particular as a working cylinder for vehicle engines, compressors u. dg1. The present invention relates to air-cooled ones made of light metal Working cylinders, in particular for vehicle engines, compressors and the like. The working surface or piston raceway consists of a permanently inserted cylinder, the is made of a material suitable as a piston running surface.

Bei derartigen Zylindern tritt häufig der Übelstand auf, daß infolge ungleichmäßiger Dehnung bei hohen Temperaturen zwischen beiden Zylindern ein wenn auch geringer Zwischenraum besteht, durch welchen der Explosions- oder Kompressionsdruck so stark verringert wird, daß die Leistung der Maschine dadurch beeinträchtigt wird.In such cylinders, the disadvantage often occurs that as a result Uneven stretching at high temperatures between the two cylinders if there is also a small gap through which the explosion or compression pressure is decreased so much that it affects the performance of the machine.

Durch die den Gegenstand der Erfindung bildende Ausbildung derartiger Arbeitszylinder wird nun der bezeichnete Übelstand dadurch vermieden, daß der innere Zylinder Rippen o. dgl. aufweist, welche in die Wandung des äußeren Leichtmetallzylinders hineinragen, und zwar zweckmäßig an den durch Kühlrippen o. dgl. verstärkten Stellen desselben.By forming the subject of the invention such training Working cylinder is now the designated disadvantage avoided in that the inner Cylinder ribs o. The like. Which in the wall of the outer light metal cylinder protrude, specifically at the points reinforced by cooling fins or the like same.

Die Herstellung des beschriebenen Zylinders kann zweckmäßig so erfolgen, daß um den mit Rippen versehenen inneren Zylinder der äußere Leichtmetallzylinder so herumarnegossen wird, daß die Rippen des ersteren innerhalb der Ansätze oder Kühlrippen des letzteren zu liegen kommen. Bei einer Erwärmung des so eingefügten Arbeitszylinders wird ein Undichtwerden durch ungleiche Dehnung der beiden Materialien deshalb nicht eintreten, weil der Leichtmetallzylinder und seine Ansätze bzw. Kühlrippen die Rippen des inneren Zylinders infolge der größeren Wärmedehnung des Leichtmetalls so einschnüren und in der Achsrichtung des Zylinders von beiden Seiten zwischen sich pressen, daß ein Durchgang von verdichteter Luft oder Explosionsgemisch, ausgeschlossen ist.The cylinder described can advantageously be manufactured in such a way that that around the ribbed inner cylinder of the outer light metal cylinder is so wrapped around that the ribs of the former within the lugs or The cooling fins of the latter come to rest. With a warming of the so inserted The working cylinder will leak due to unequal expansion of the two materials therefore do not occur because of the light metal cylinder and its approaches or cooling fins the ribs of the inner cylinder due to the greater thermal expansion of the light metal so constrict and in the axial direction of the cylinder from both sides between press so that a passage of compressed air or explosive mixture is excluded is.

Eine Ausführungsform des Erfindungsgegenstandes ist in der zugehörigen Zeichnung im Ouerschnitt veranschaulicht. Es bezeichnet a den äußeren Leichtmetallzylinder mit Kühlrippen b, c den inneren Zylinder mit in die Kühlrippen b des Außenzylinders ca hineinragenden Rippen d.An embodiment of the subject matter of the invention is in the associated Drawing illustrated in cross-section. It denotes a the outer light metal cylinder with cooling fins b, c the inner cylinder with the cooling fins b of the outer cylinder ca protruding ribs d.

Beim Ausführungsbeispiel weist der innere Zylinder c drei Rippen d auf und der äußere Leichtmetallzylinder a sechs Kühlrippen b. Von diesen sind die beiden obersten, am Zylinderkopf befindlichen, und die unterste ohne Einfügung einer Rippe des inneren Zylinders c angenommen, indem letztere nur am oberen Ende des inneren Zylinders c vorgesehen sind, wo die Wärmeentwicklung am größten wird.In the exemplary embodiment, the inner cylinder c has three ribs d on and the outer light metal cylinder a six cooling fins b. Of these are the the top two, located on the cylinder head, and the bottom without the insertion of a Rib of the inner cylinder c assumed by placing the latter only at the top of the inner cylinder c are provided where the heat generation is greatest.

Außer dem eingangs angeführten Vorteil besserer Abdichtung ist durch die Erfindung noch eine bessere Wärmeableitung geschaffen für den inneren Zylinder, da, wo dieser am wärmsten wird, indem eine größere Außenfläche desselben mit dem umgebenden Leichtmetallzylinder verbunden ist.In addition to the aforementioned advantage of better sealing is through the invention created even better heat dissipation for the inner cylinder, where it becomes warmest, by having a larger outer surface with it surrounding light metal cylinder is connected.
