Description

Die Erfindung betrifft eine Luftkühlvorrichtung für Brennkraftmaschinen, bei, der die ausströmenden Auspuffgase in bekannter Weise dazu benutzt werden, Frischluft anzusaugen, die bei ihrem Durchgang zwischen Kühlrippen des Zylinders diese Rippen und damit auch den Zylinder kühlt.The invention relates to an air cooling device for internal combustion engines, at which the exhaust gases flowing out are used in a known manner to provide fresh air to suck in these ribs as they pass between cooling fins of the cylinder and thus also cools the cylinder.

Es ist bekannt, konzentrisch zum Zylinder einen Kühlmantel vorzusehen, der an parallel zur Zylinderachse verlaufenden Rippenkanten befestigt ist.It is known to provide a cooling jacket concentric to the cylinder, which is attached to rib edges running parallel to the cylinder axis.

Die Erfindung sieht eine Luftkühlvorrichtung für den oberen Teil des Zylinders von Brennkraftmaschinen vor, und zwar eine Luftkühlvorrichtung, bei der ein in der Zylinderachse und im Zylinderdeckel angeordnetes Einlaßventil von einem rohrförmigen Ventil und dieses außerhalb des Zylinderkopfes von einer ringförmigen Ausströmleitung für die Auspuffgase umschlossen ist, wobei diese Ausströmleitung mit Kanälen, die durch in der Längsrichtung des Zylinders verlaufende radiale Kühlrippen und einen diese umgebenden zylindrischen Mantel gebildet sind, durch ringförmige, unter Ausnutzung der Strömungsenergie der Abgase dös Ansaugen von Frischluft durch die besagten Kanäle bewirkende Düsen in Verbindung steht.The invention provides an air cooling device for the upper part of the Cylinder of internal combustion engines before, namely an air cooling device in which an inlet valve arranged in the cylinder axis and in the cylinder cover of one tubular valve and this outside of the cylinder head by an annular Outflow line for the exhaust gases is enclosed, this outflow line with channels through radial cooling fins running in the longitudinal direction of the cylinder and a cylindrical jacket surrounding them are formed by annular, taking advantage of the flow energy of the exhaust gases sucking in fresh air nozzles effecting said channels is in communication.

Eine Vorrichtung gemäß der Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Fig. i einen senkrechten Schnitt durch die Vorrichtung und Fig.2 einen waagerechten Teilschnitt nach der Linie II-II der Fig. i.A device according to the invention is in the drawing in one Embodiment shown, namely Fig. I shows a vertical section through the device and FIG. 2 a horizontal partial section along the line II-II of Fig. i.

Der Zylinder z des Motors ist auf seiner Außenseite mit ringförmigen Rippen 2 versehen, während der von dem Zylinder getrennte und mit diesem verschraubte Zylinderkopf parallel zu seiner Achse verlaufende radiale Rippen 23 aufweist, die in Richtung der erzeugenden Mantellinie oder schraubenförmig verlaufen.The cylinder z of the engine is annular on its outside Ribs 2 provided, while the separated from the cylinder and screwed to this The cylinder head has radial ribs 23 extending parallel to its axis, which run in the direction of the generating surface line or helically.

Im oberen Teil des Zylinders ist ein Einlaßventil io angeordnet, das von einem rohrförmigen Ventil g überragt wird, wobei die Steuerung der Ventile durch Schwinghebel 17 und iS und eine Feder 28 erfolgt.In the upper part of the cylinder an inlet valve io is arranged, which is surmounted by a tubular valve g, the valves being controlled by rocker arms 17 and iS and a spring 28 .

Die radialen Rippen 2.3 sind von einem zylindrischen Mantel a4 umgeben.The radial ribs 2.3 are surrounded by a cylindrical jacket a4.

Die angesaugte Luft tritt bei 26 in den Mantel 24. ein, strömt durch die Düsen 25 und gelangt -in die ringförmige Kammer 13.The sucked in air enters the jacket 24 at 26 , flows through the nozzles 25 and reaches the annular chamber 13.

Die Auspuffgase strömen durch den ringförmigen, divergierenden Kanal 14 spiralförmig in den Sockelraum 15, wobei sie über die Düsen 25 Frischluft durch die zwischen den Rippen 23 liegenden Kanäle ansaugen.The exhaust gases flow through the annular, diverging duct 14 spirally into the base space 15, with fresh air through the nozzles 25 the ducts lying between the ribs 23 suck in.

Das Frischgas wird bei 22 zugeführt.The fresh gas is supplied at 22.
