Bei Umlaufsmotoren, insbesondere Flugmotoren, bestehen hinsichtlich der olzuführung Schwierigkeiten, insofern, als die Ölzuführungsleitungen, die in dem Ansaugekanal des Gasgemisches angebracht werden, leicht zufrieren. . Besonders nachteilig tritt dieser Umstand in Erscheinung bei Verwendung· von Rizinusöl als Schmiermittel, das gerade für Flugmotoren in Betracht kommt, aber schon bei einigenIn the case of rotary engines, in particular aircraft engines, there is a need for oil supply Difficulties insofar as the oil supply lines, which are placed in the suction channel of the gas mixture can easily freeze over. . This fact occurs particularly disadvantageously Appearance when using castor oil as a lubricant, especially for aircraft engines comes into consideration, but with some
ίο Graden unter Null zu einer gallertartigen Masse gefriert, welche die Rohrleitungen verstopft. Das Wesen der Erfindung besteht nun darin, daß die Ölzuleitungen in einem besonderen, vor der Gemischansaugung völlig geschützt liegenden Raum der hohlen Kurbelwelle stattfindet, und zwar an einer Stelle, welche bis zu gewissem Grade von den Verbrennungszylindern erhitzt wird, wodurch die Gefahr des Einfrierens wesentlich verringert wird.ίο degrees below zero to a gelatinous mass freezes, which clogs the pipes. The essence of the invention now consists in that the oil supply lines in a special, completely protected from the mixture intake lying space of the hollow crankshaft takes place, at a point which up is heated to some extent by the combustion cylinders, thus reducing the danger freezing is significantly reduced.
In der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführung dargestellt, und zwar zeigt Fig. 1 einen senkrechten Längsschnitt, Fig. 2 einen wagerechten Längsschnitt, Fig. 3 einen Querschnitt durch die Kurbel.In the drawing, the subject matter of the invention is shown in an exemplary embodiment, namely, FIG. 1 shows a vertical longitudinal section, FIG. 2 shows a horizontal section Longitudinal section, Fig. 3 shows a cross section through the crank.
In der hohlen Kurbelwelle 1 ist ein mehrteiliger Einsatzkörper angeordnet. Dieser besteht aus den ölzuleitungsrohren 2, einem mittleren Rohr 3 und zwei Rohrstücken 4 und 5. Das Rohr 3 ist dabei exzentrisch zur hohlen Kurbelwelle 1 angeordnet, so daß ein von dem Innenraum des Rohres 3 abgesonderter luftisolierter Raum 6 für die Ölrohre 2 entsteht. Diese Ölrohre liegen also von dem Ansaugekanal für das Gemisch, d. h. dem Innenraum des Rohres 3, vollständig getrennt und geschützt, so daß die Gefahr des Einfrierens dieser Rohre wesentlich herabgesetzt wird. Dem Rohrstück 5 wird das öl von außen durch Stutzen 7 zugeführt, während im Rohrstück 4 die Kanäle für den Ölablauf nach den verschiedenen Zapfen und Lagerstellen angeordnet sind, wie aus Fig. 1 und 2 der Zeichnung hervorgeht.In the hollow crankshaft 1 is a multi-part Insert body arranged. This consists of the oil supply pipes 2, one middle pipe 3 and two pipe pieces 4 and 5. The pipe 3 is eccentric to hollow crankshaft 1 arranged so that a separated from the interior of the tube 3 Air-insulated space 6 for the oil pipes 2 is created. So these oil pipes are from that Intake duct for the mixture, d. H. the interior of the tube 3, completely separated and protected, so that the risk of freezing these pipes is significantly reduced will. The pipe section 5 is supplied with the oil from the outside through nozzle 7, while in the Pipe section 4 arranged the channels for the oil drain after the various pins and bearings are, as can be seen from Figs. 1 and 2 of the drawing.
