Description
Gekühltes Zylinderfutter für Verbrennungsmotoren. Das Zylinderfutter von Verbrennungsmotoren unterliegt an dem dem Kompressionsraum naheliegenden Ende sehr erheblichen mechanischen Beanspruchungen durch den hohen inneren Druck. Infolgedessen muß der Befestigungsflansch des Innenfutters eine beträchtliche Wandstärke haben, ,die auch notwendig ist, um dichte Anschlußflächen an dem äußeren Zylinderkörper und dem Zylinderkopf zu erzielen. Infolgedessen treten an dieser Stelle erhebliche Wärmestauungen auf, und man hat deshalb versucht, eine Ergänzungskühlung anzuwenden, indem man im Befestigungsflansch einen Umlaufkanal eingießt, der mit dem Wassermantel des Zylinders Verbindung hat. Durch diesen Umlaufkanal kvird jedoch der Guß des. Zylinderfutters erschwert.Cooled cylinder liner for internal combustion engines. The cylinder chuck of internal combustion engines is subject to the end close to the compression chamber very considerable mechanical stresses due to the high internal pressure. Consequently the mounting flange of the inner lining must have a considerable wall thickness, , which is also necessary to provide tight connection surfaces on the outer cylinder body and the cylinder head. As a result, significant occur at this point Heat build-up, and attempts have therefore been made to use additional cooling, by pouring a circulation channel into the mounting flange, which is connected to the Water jacket of the cylinder has connection. Through this circulation channel, however, the casting of the. Cylinder chuck difficult.
Gemäß der vorliegenden Erfindung wird dieser Nachteil dadurch beseitigt, daß im Befestigungsflansch des Zylinderfutters eine offene Nut ausgespart ist, in welcher ein Kühlroter angeordnet ist, das in einer die Wärme gut leitenden Legierung eingebettet ist.According to the present invention, this disadvantage is eliminated by that an open groove is recessed in the mounting flange of the cylinder chuck, in which a cooling element is arranged, which is made of an alloy that conducts heat well is embedded.
In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt.In the drawing is an embodiment of the subject matter of Invention shown.
Abb. i zeigt einen achsialen Schnitt durch das Zylinderende.Fig. I shows an axial section through the end of the cylinder.
Abb. 2 zeigt einen Schnitt nach Linie A-B der Abb. i.Fig. 2 shows a section along line A-B of Fig. I.
Das Zylinderfutter i wird von dem Mantel 2 durch einen Hohlraum 3 getrennt, in welchem das Kühlwasser umläuft. Der Flansch i' zur Befestigung des Futters am Mantel und Zylinderkopf besitzt nun einen offenen, ringförmigen Kanal q., der beispielsweise beim Abdrehen des Futters auf der Bank hergestellt werden kann. In diesen Kanal 4. wird ein in geeigneter Form gekrümmtes Rohr 7 eingelegt, das an einem Ende mit einem Anschluß 5 für den Kühlwassereintritt und am anderen Ende mit einem Anschluß 6 für den Kühlwasseraustritt versehen ist. Um eine gute Wärmeübertragung vom Futter auf das Kühlrohr zu erreichen, wird der Ringkanal q' mit einer die Wärme gut leitenden Legierung ausgegossen.The cylinder chuck i is attached to the jacket 2 through a cavity 3 separated, in which the cooling water circulates. The flange i 'for fastening the The lining on the jacket and cylinder head now has an open, ring-shaped channel q., which can be made, for example, when turning the chuck on the bench can. In this channel 4. a suitably curved pipe 7 is inserted, that at one end with a connection 5 for the cooling water inlet and at the other The end is provided with a connection 6 for the cooling water outlet. To be good To achieve heat transfer from the feed to the cooling pipe, the annular channel q ' poured with an alloy that conducts heat well.
Natürlicherweise kann man von der Form und den Konstruktionseinzelheiten der dargestellten Ausführungsform abweichen, ohne den Rahmen der Erfindung zu verlassen.Of course one can tell from the shape and the construction details deviate from the illustrated embodiment without departing from the scope of the invention.
