Description
Kühlung der Kolben von Verbrennungskraftmaschinen mit kreisenden Zylindern. Die Erfindung bezieht sich auf die Kühlung von Verbrennungskraftmaschinen mit kreisenden Zylindern, deren Kolben paarweise mittels durchgehender Kolbenstangen zu gleicher Bewegung verbunden sind. .Cooling of the pistons of internal combustion engines with rotating cylinders. The invention relates to the cooling of internal combustion engines with circular Cylinders whose pistons are identical in pairs by means of through piston rods Movement are connected. .
Diese Kraftmaschinen erfordern wegen des großen Kolbenweges und wegen ihrer hohen Umfangsgeschwindigkeit eine möglichst lebhafte Kühlung, und zwar genügt es nicht, daß die Zylinder durch die Luft gekühlt werden, sondern, es ist nötig, auch die Kolben zu kühlen, damit sie am Heißlaufen gehindert werden.These engines require because of the large piston travel and because of Their high circumferential speed, a cooling that is as lively as possible, and that is sufficient it is not that the cylinders are cooled by the air, but rather, it is necessary also to cool the flasks so that they are prevented from overheating.
Gemäß der Erfindung wird die beim, Umlauf der Zylinder erzeugte Fliehkraft dazu benutzt, innerhalb der Kolbenstangen, und Kolben die Zirkulation des Kühlwassers herbeizuführen, und zwar ist die Ausbildung so getroffen, daß die gleiche Flüssigkeitsmenge der Reihe nach je zwei durch eine gemeinsame Kolbenstange gekuppelte Kolben durchfließt und erst hierauf den Motor verläßt.According to the invention, the centrifugal force generated during rotation of the cylinder used to circulate the cooling water within the piston rods and pistons bring about, namely the training is made so that the same amount of liquid in turn flows through two pistons coupled by a common piston rod and only then leaves the engine.
Die Zeichnung veranschaulicht beispielsweise einen wagerecht umlaufenden vierzylindrigen Motor in schematischer Darstellung.The drawing illustrates, for example, a horizontally circulating one four-cylinder engine in a schematic representation.
Die Zuführung des Kühlwassers nach dem Gehäuse 1a erfolgt durch das Rohr v, das beispielsweise bei Außenbordmotoren in, das Schwimmwasser eintaucht und von dem eine Abzweigleitung y' nach den Wasserkammern s s' der beiden Zylinder a a' führen. Die Wasserkammer s ist mit der Wasserkammer s" des Zylinders b durch die Umströmleitung r" verbunden. In. gleicher Weise kann die Wasserkammer s' durch eine Umströmleitung mit der Wasserkammer s"' verbunden werden.The cooling water is fed to the housing 1a through the pipe v, which is immersed in the swimming water in the case of outboard motors, for example, and from which a branch line y 'leads to the water chambers ss' of the two cylinders a a' . The water chamber s is connected to the water chamber s ″ of the cylinder b through the bypass line r ″ . In. In the same way, the water chamber s 'can be connected to the water chamber s''' by a flow line.
Die hohl gestalteten Kolbenstangen d g werden an ihren beiderseitigen. Enden in den Rohren t t' geführt, finit denen sie durch Stopfbüchsen dichtschließend zu verbinden sind. Nach diesen Rohren t führen an die Wasserkammern s' und s" angeschlossene Rohrleitungen u.The hollow piston rods dg are on both sides. Ends in the pipes t t ' , finite which they are to be connected tightly by means of stuffing boxes. After these pipes t lead to the water chambers s' and s "connected pipes u.
An die Führungsrohre t' sind Abspritzrohre v angeschlossen, deren Mündungen offen sind, so daß, wenn die Zylinder ihre kreisende Bewegung ausführen" das Kühlwasser nur an, diesen beiden Rohren v austreten kann, wo es durch den zentrifugalen Luftstoß nach außen geschleudert wird. Das bei v austretende Kühlwasser verursacht in der Kühlleitung eine solche Saugwirkung, daß das Kühlwasser, dessen Eintritt, wie bereits erwähnt, durch die Zuleitung y erfolgt, seinen Weg durch die Abzweigleitungen y' nach den Wasserkammern, s s' und die Umströmleitung y" nach der Wasserkammer s" und von dort durch die Leitungen u in die Rohre t nimmt, von denen aus es die Kolbenstangen d und g sowie die Kolben P' P bzw. q' q durchfließt. Es werden infolgedessen nicht allein Kolben, sondern auch die Innenventile gekühlt, die, weil sie sich innerhalb des Gehäuses befinden, dem Festbrennen am stärksten ausgesetzt sind.Spray pipes v, the mouths of which are open, are connected to the guide pipes t ', so that when the cylinders execute their circular motion, the cooling water can only exit through these two pipes v, where it is thrown outwards by the centrifugal blast of air Cooling water exiting at v causes such a suction effect in the cooling line that the cooling water, which, as already mentioned, enters through the supply line y, makes its way through the branch lines y 'to the water chambers, ss' and the flow line y "to the water chamber s "and from there through the lines u into the tubes t, from which it flows through the piston rods d and g as well as the pistons P 'P and q' q . As a result, not only the pistons but also the internal valves are cooled, which, because they are inside the housing, are most susceptible to burning.
