Description
. Luftkühlung für Explosionskraftmaschinen. Bisher wurde die Kühlung der Arbeitszylinder von Explosionskraftwaschinen durch einen um den Zylinder angeordneten Mantel vermittelt, dessen Hohlraum durch schraubenförmig angeordnete Lamellen so unterteilt war, daß die Kühlluft in einem Strome möglichst oft -den Zylinder umstreichen muß. Die Außenwand des so unterteilten Mantels bildete eine glatte Fläche, die dem Wärmeaustausch mit der den Marterl umgebenden Außenluft nicht günstig war. Durch vorliegende Erfindung soll nun oder Wärmeaustausch der die Zylinderwand umstreichenden angewärmten Kühlluft mit (der die Kühlvorrichtung umgebenden Außenluft durch die Vergrößerung der Kü @Ifläche .erheblich gefördert werden, was dadurch geschieht, @daß die Außenluft in einer oder mehreren unabhängigen um denZylinder gewickelten, Wärme gut leitenden Röhren schraubenförmig um den Arbeitszylinder geführt wird. Diese Röhren werden zweckmäßig paarig angeordnet und wird dann in diesem Falle die Außenluft um den Zylinder von entgegengesetzten Enden derselben geführt.. Air cooling for explosion engines. So far the cooling has been the working cylinder of explosion engines by a cylinder arranged around the cylinder Sheath conveyed, the cavity of which by helically arranged lamellae so was divided so that the cooling air in a stream as often as possible -circle the cylinder got to. The outer wall of the jacket so divided formed a smooth surface that the Heat exchange with the outside air surrounding the Marterl was not favorable. By The present invention is now or heat exchange of the cylinder wall stroking heated cooling air with (the outside air surrounding the cooling device through the Enlargement of the cooling surface. Are promoted significantly, what happens thereby, @ that the outside air is wrapped around the cylinder in one or more independent Heat well conductive tubes are helically guided around the working cylinder. These tubes are expediently arranged in pairs and in this case becomes the Outside air is passed around the cylinder from opposite ends thereof.
Die Zeichnung stellt zwei Ausführungsbeispiele der Luftkühlung gemäß der Erfindung in,.. Abb. i mit einfacher, in Albb. 2 mit doppelter Rohrschlange, teils in Ansicht, teils im Schnitt idar.The drawing represents two embodiments of the air cooling according to of the invention in, .. Fig. i with simpler, in Albb. 2 with double pipe coil, partly in view, partly in section idar.
Abb. 3 und .4 sind zwei wagerechte Schnitte nach Linie III-III bzw. IV-IV der Abb. 2.Fig. 3 and .4 are two horizontal sections along line III-III and IV-IV of Fig. 2.
In dem Ausführungsbeispiel nach Abb. i und 3 ist @die Rohrschlange b schraufbenförmig um den Zylinder a gelegt und wird als Rohr e zum Vergaser f und von dort als Rohr g in den Zylinder a geführt. Die Luft tritt :durch den Trichter c in die Kühlschlange b ein. In dem Ausführungsbeispiel nach Abb.2 und 4. sind zwei Rohrschlangen b und b' um den Zylinder agelegt; die an die zum Vergaser führenden Rohre e, e' angeschlossen sind.In the exemplary embodiment according to Figs. I and 3, the pipe coil b is laid helically around the cylinder a and is fed as a pipe e to the carburetor f and from there as a pipe g into the cylinder a. The air enters: through the funnel c into the cooling coil b. In the exemplary embodiment according to FIGS. 2 and 4, two pipe coils b and b 'are placed around the cylinder; which are connected to the pipes e, e ' leading to the carburetor.
Die Kühlluft tritt in Rohrschlange b durch das trichterförmig erweiterte Endstück c, in Rohrschlange b' (durch c' .ein und wird um den Zylinder von ibeiden Enden c, c' in entgegengesetzter Richtung geführt. Die Pfeile (Abb. 2) zeigen den Weg der Luft in beiden Rohrschliangen -in zwei entgegengesetzt gerichteten Strömen. Die erhitzte Luft wird zweckmäßig in den Vergaser igeleitet. Die Bewegung der Luft durch. dieRöhrschlange b (Abb. i) ikann idadurch gefördert werden, @daß letztere @durch Rohr g -an das Gasansaugventil d des Zylinders a angeschlossen ist, 5o ,daßauch die S[augwirkun[g des Kolbens im Zylinder a zur Kühlung nutzbringend verwertet wird.The cooling air enters coil b through the widened funnel-shaped End piece c, in pipe coil b '(through c' .ein and is around the cylinder of ibeiden Ends c, c 'out in the opposite direction. The arrows (Fig. 2) show the Path of the air in both pipe coils - in two oppositely directed currents. The heated air is expediently directed into the carburetor. The movement of the air by. the tube snake b (Fig. i) i can be promoted by @ that the latter @Through pipe g - is connected to the gas suction valve d of the cylinder a, 5o that also the suction effect of the piston in the cylinder a is used to good effect for cooling.
