Description
Kolbenkühlvorrichtung für Verbrennungskraftmaschinen. Um Verbrennutigsniotoren großer Abmessungen und großer Drehzahlen betriebssicher laufen lassen zu können, ist eine Kühlung des von Flammen bespülten Kolbenbodens nötig.Piston cooling device for internal combustion engines. About combustion engines to be able to run reliably with large dimensions and high speeds, It is necessary to cool the piston crown, which has been flushed with flames.
Ferner zeigen diese 'Maschinen den großen Cbelstand, daß durch das mit großer Geschwindigkeit von den Triebteilen abspritzende C51 die Zvlinderlaufbahn übermäßig geschmiert wird und Öl in den Verbrennungsrauin übertritt, «-as ein frühzeitiges Verschmutzen der Maschine herbeiführt.Furthermore, these machines show the great condition that the cylinder raceway is excessively lubricated by the C51 spraying off the drive parts at high speed and oil leaks into the combustion chamber, which leads to premature soiling of the machine.
Bei bisherigen Konstruktionen hat man versucht. das Öl durch teleskopartig ineinandergleitende Rohre dein Kolben zu- und abzuführen. Bei den hohen Kolbengeschwindigkeiten von Hochleistungsmotoren ist dies nicht mehr möglich.Attempts have been made with previous designs. the oil through telescopic pipes sliding into one another to feed and discharge your piston. At the high piston speeds This is no longer possible with high-performance engines.
Nach beiliegender Zeichnung ist ein Ülzti-und Ableitungsverfahren zum Kolben dargestellt, welches gleichzeitig eine übermäßige Schmierung der Zvlinderlaufbalin vermeidet. Aus der Fig. t ist zu erkennen, daß durch das Kurbellager bei a in die hohle Kurbelwelle b Öl unter solch hohem Druck eingeführt wird, daß dasselbe entgegen der Zentrifugalkraft durch das Rohr c der Pleuelstange d in den hohlen Kolbenbolzen e und von da durch Bohrung in den Zwischenraum des Kolbens f gelangen kann. Von hieraus gelangt das Öl durch die Bohrung a in ein Rohr )i, «-elche, finit der Bohrung g verbunden ist. Das Rohr h ragt in jeder Kolbenstellung durch eine kleine Öffnung i in einen Kasten k hinein, so da13 das durch das Rohr lt austretende heiße Ö1 nicht im Kurbelkasten herumspritzen kann, sondern durch die im Kasten unten seitlich angeordneten Öffnungen I in die Wanne des Kurbelkastens abfließt, ohne dabei die Kurbelwellenlager zu bespülen. Von da wird das Öl abgesaugt und durch einen Kühlapparat rückgekühlt. Da das unter ziemlich hohem Druck stehende Ö1 durch Unclichtigkeiten des Pleuelstangenlagers zu entweichen trachtet, so sind die Pleuelstan, gcnenden bei in mit Abspritzringen versehen. Am Kurbelarm sind mitrotierende Ölfangringe ii vorgesehen, so daß das vom Pleuellager abspritzende C51 in diesen aufgefangen wird und durch eine seitlich angeordnete Ü -f"tnung o 'von der Kolbenlaufbahn abgelenkt wird.According to the accompanying drawing, an Ülzti and discharge method for the piston is shown, which at the same time avoids excessive lubrication of the cylinder barrel balin. From Fig. T it can be seen that through the crank bearing at a in the hollow crankshaft b oil is introduced under such high pressure that the same against the centrifugal force through the pipe c of the connecting rod d into the hollow piston pin e and from there through the bore can get into the space of the piston f. From here the oil passes through the bore a into a pipe) i, «-which is finitely connected to the bore g. In every piston position, the tube h protrudes through a small opening i into a box k, so that the hot oil escaping through the tube lt cannot splash around in the crankcase, but instead flows through the openings I at the bottom of the box into the tub of the crankcase without flushing the crankshaft bearings. From there the oil is sucked off and recooled by a cooling device. Since the oil, which is under fairly high pressure, tends to escape through imperfections in the connecting rod bearing, the connecting rods are provided with spray-off rings. On the crank arm, co-rotating oil catch rings ii are provided so that the C51 spraying off the connecting rod bearing is caught in these and is deflected from the piston raceway by a laterally arranged Ü-opening o '.
