Description

  

  Einrichtung zur Zylinderkühlung bei luftgekühlten Motoren.    Die     Kühlung    der     Zylinder    erfolgt bei       luftgekühlten;        Motoren;        ,gewöhnlich    so, dass  die     Luft    auf der     einen:        Seite    quer     zum,        Zy-          lindeT    zugeführt und auf der andern Seite       abgeleitet        wird,    weshalb der Zylinder sehr       ungleichmässig    gekühlt wird.

   Es wurde des  halb     vorgeschlagen,    den     Zylinder    durch  einen in     Richtung    der     Zylinderachse        fliessen-          ,den    Luftstrom zu kühlen. Bei dieser     Kühl-          einrichtung    verlaufen dann die Rippen der  Zylinder in der     Richtung    der Zylinderachse.  Diese     Rippenanordnung    ist aber in bezug  auf das Giessen sehr     kompliziert.     



       Bei    der     Einrichtung    zur Zylinderküh  lung nach der     Erfindung    sind auf dem Zy  linder senkrecht zur Zylinderachse Rippen       angebracht,    die mit ,in einer Flucht in Rich  tung der     Zylinderachse    angeordneten Löchern  für den Durchgang :

  der     Kühlluft        versehen!          sind.    Hierbei     sind.    die Löcher für den Ein  tritt der Kühlluft in !das System der zur       Zylinderachse        oenkrechten    Rippen zweck-         mässig        zwischen    in     Richtung        zur        Zylinder-          achse    verlaufenden Rippen des     Zylinder-          kopfes    vorgesehen und der Durchmesser der  Löcher in     den;        Zylinderrippen:

      wird     vorteil-          haft    von Rippe zu Rippe in der Richtung       ,des        Luftstromes        kleiner,    so     dass        .die    vom       Zylinderkopf    her     zuströmende    Luft     aufein-          anderfolgend    auf alle Rippen( verteilt     wird-.     



  In der     Zeichnung        ist        ein.        Ausführungs-          beispiel    des Erfindungsgegenstandes veran  schaulicht, und zwar     zeigt          Fig.    1 den:     Grundriss    eines     Zylinders        eines     luftgekühlten     Motors    in     Ansicht    und       Fig.    2     einen        Längsschnitt    nach Linie       I-I    in     Fig.    1.  



  Der     Zylinder    1 mit .dem Kopf 2 wird  von dem von oben nach     unten        gerichteten          Luftstrom        .3        gekühlt.        Zwischen        den,    in     Rich-          tung    der Zylinderachse verlaufenden Rip  pen 4 des     Zylinderkopfes    2 sind     in:

          einer     senkrecht zu diesen     stellenden        .Rippe    vier  Löcher vorgesehen, denen die Löcher 5 in      den senkrecht zur Zylinderachse     angehrach-          ten    Rippen 6 des     Zylinders    entsprechen,  deren Durchmesser von Rippe zu Rippe  kleiner wird, wodurch die Kühlluft zwischen  den     Rippen    in vollkommener \'eise verteilt  wird. Die     Ueher    5 sind in einer Flucht in  Richtung der     Zylinderaehse        angeordnet.  



  Device for cylinder cooling in air-cooled engines. The cylinders are cooled with air-cooled; Engines; , usually in such a way that the air is supplied on one side across the cylinder and is discharged on the other side, which is why the cylinder is cooled very unevenly.

   It was therefore proposed to cool the cylinder by means of a flow of air in the direction of the cylinder axis. In this cooling device, the ribs of the cylinders then run in the direction of the cylinder axis. However, this rib arrangement is very complicated with regard to casting.



       In the device for cylinder cooling according to the invention, ribs are attached to the cylinder perpendicular to the cylinder axis, with holes arranged in alignment in the direction of the cylinder axis for the passage:

  the cooling air! are. Here are. the holes for the entry of the cooling air into the system of ribs perpendicular to the cylinder axis are expediently provided between ribs of the cylinder head running in the direction of the cylinder axis and the diameter of the holes in the cylinder head; Cylinder ribs:

      is advantageously smaller from rib to rib in the direction of the air flow, so that the air flowing in from the cylinder head is distributed to all ribs one after the other.



  In the drawing is a. Exemplary embodiment of the subject matter of the invention is illustrated, namely FIG. 1 shows the plan view of a cylinder of an air-cooled engine and FIG. 2 shows a longitudinal section along line I-I in FIG.



  The cylinder 1 with the head 2 is cooled by the air flow 3 directed from top to bottom. Between the ribs 4 of the cylinder head 2, which run in the direction of the cylinder axis, are:

          A rib perpendicular to these four holes are provided, to which the holes 5 correspond in the ribs 6 of the cylinder attached perpendicular to the cylinder axis, the diameter of which becomes smaller from rib to rib, so that the cooling air is perfectly distributed between the ribs becomes. The Ueher 5 are arranged in alignment in the direction of the cylinder axis.
