Abstract

Die Erfindung bezieht sich auf eine Kühl- und Schmiermittelführung für Brennkraftmaschinen. Bei Brennkraftmaschinen ist es üblich, Kühl- und Schmiermittel zunächst über Kanäle im Kurbelgehäuse zu führen und vom Kurbelgehäuse über Durchtritte in der Zylinderkopfdichtung in den Zylinderkopf zu leiten. Erfindungsgemäß werden diese Durchtritte durch die Zylinderkopfdichtung 4 vermieden, indem an einer der Stirnseiten des Motors ein Verteilerstück 5 vorgesehen wird, über welches Kühl- und Schmiermittel dem Kurbelgehäuse 2 und dem Zylinderkopf 3 getrennt zugeführt wird. Das Kühlmittel wird über Kühlwasserzulaufkanäle 6a, 6b zu- und über Kühlwasserablaufkanäle 10a, 10b abgeführt. Das Öl wird über Ölzulaufbohrungen 7a, 7b zu- und über Ölablaufbohrungen 9a, 9b abgeführt. Durch die stirnseitige Zu- bzw. Abfuhr von Kühl und Schmiermittel entfalten alle zu Leckagen neigenden Durchtritte durch die Zylinderkopfdichtung 4, welche allein auf die Funktion der Brennraumabdichtung hin optimiert werden kann.

Figure 00000001
The invention relates to a coolant and lubricant guide for internal combustion engines. In internal combustion engines, it is customary to first pass coolants and lubricants through channels in the crankcase and to guide them from the crankcase into the cylinder head via openings in the cylinder head gasket. According to the invention, these passages through the cylinder head gasket 4 are avoided by providing a distributor piece 5 on one of the end faces of the engine, via which coolant and lubricant are fed separately to the crankcase 2 and the cylinder head 3. The coolant is supplied via cooling water inlet channels 6a, 6b and removed via cooling water outlet channels 10a, 10b. The oil is supplied via oil inlet bores 7a, 7b and discharged via oil outlet bores 9a, 9b. Due to the supply and discharge of coolant and lubricant on the front side, all the passages tending to leak through the cylinder head gasket 4 unfold, which can be optimized solely for the function of the combustion chamber seal.
