Description

Luftgekühlter Zylinder für Brennkraftmaschinen Der Gegenstand der Erfindung bildet einen luftgekühlten Zylinder für Brennkraftmaschinen o. dgl., der mit einem Mantel umgeben ist und bei dem die Luft zwischen Zvlinderwand und Ummantelung hindurchgeblasen wird.Air-cooled cylinder for internal combustion engines The subject of Invention forms an air-cooled cylinder for internal combustion engines o. The like., The is surrounded by a jacket and in which the air between the cylinder wall and the jacket is blown through.

Um eine wirksame Abführung der Wärme dabei zu erreichen, hat man bereits die äußere Ummantelung mit der Zylinderwand durch Wärmeableitflächen verbunden, die mit den beiden Wänden in metallischer Verbindung stehen. Dadurch wird eine bessere Wärmeableitung erzielt, einmal durch die Durchwirbelung und Aufteilung der hindurchgeblasenen Luft und dann dadurch, daß außer der Wärmeabführung durch die Kühlluft noch eine Wärmeableitung durch die Ausstrahlung der in metallischer Verbindung stehenden Flächen erfolgt. Derartige Wärmeableitflächen, die meist die Form von einfachen Rippen haben, lassen sich aber nur bei glatten Zylindern anbringen, die bei Brennkraftmaschinen in den meisten Fällen nicht vorliegen, da durch Ventilgehäuse, besondere Ausbildung der Verbrennungsräume u. dgl. unregelmäßige Formen entstehen. Um bei solchen Zylindern die an sich sehr wirksame Kühlung mit billigen Mitteln zu erzielen, soll nach der Erfindung der Zwischenraum zwischen Zylinderwand und Ummantelung mit leicht rollenden Körpern ausgefüllt werden, wie z. B. Kugeln oder ähnlichen Körpern, die sich. leicht nach Herstellung des Mantels einfüllen lassen und jeden Zwischenraum ausfüllen. Darauf werden diese Körper nach irgendeinem bekannten Verfahren, beispielsweise durch Zusammensintern, Eintauchen in Lötmasse o. dgl., miteinander in metallische Verbindung gebracht. Auf diese Weise wird eine billige Herstellung erzielt, die bei jeder beliebigen Zylinderform anwendbar ist. Die einzeln eingefüllten Metallkörper können für sich selbst auch wieder durchbrochen sein.In order to achieve an effective dissipation of the heat, one already has the outer casing is connected to the cylinder wall by heat dissipation surfaces, which are in metallic connection with the two walls. This will make a better one Heat dissipation achieved, once through the swirling and division of the blown through Air and then by the fact that, in addition to the heat dissipation through the cooling air, another Heat dissipation through the radiation of the metallic connected surfaces he follows. Such heat dissipation surfaces, which usually have the shape of simple ribs, but can only be attached to smooth cylinders that are used in internal combustion engines in most cases not available, due to the valve housing, special training the combustion chambers and the like result in irregular shapes. To with such cylinders to achieve the very effective cooling with cheap means, should after the Invention of the space between the cylinder wall and casing with easy rolling Bodies to be filled in, such as B. balls or similar bodies that are. easy After the casing has been made, let it fill in and fill in every space. These bodies are then made by any known method, for example by sintering together, dipping in solder or the like, with one another in metallic Connected. In this way a cheap production is achieved is applicable to any cylindrical shape. The individually filled metal bodies can also be broken through again for themselves.

Auf der Zeichnung ist der Erfindungsgegenstand in einem Beispiel dargestellt. a ist der Zylinder, b die Ummantelung, c die Füllung mit Metallkörpern, d ein Ventilator.The subject of the invention is shown in an example in the drawing. a is the cylinder, b the casing, c the filling with metal bodies, d a fan.
