Description

  

      Zylinderdeckel    mit Kühlraum, insbesondere für     doppeltwirkende        Brennkraftmasehinen.       Die Erfindung     betrifft    einen Zylinder  deckel mit Kühlraum, insbesondere     für    dop  peltwirkende     Brennkraftmaschinen,    bei dem  ein die Öffnung für eine durchgehende Kol  benstange und Stutzen für Ventile enthal  tender Deckelkörper mittelst einem die     Dek-          kelschraubenlöcher    enthaltenden ringförmigen       Anpresskörper    an den Zylinder     angepresst     wird.

   Bei den bisherigen Zylinderdeckeln  dieser Art ist eine einwandfreie Kühlung der  Ventilstutzen aus dem Grunde nicht möglich,  weil die neben der zentralen     Kolbenstangen-          öffnung    angeordneten Ventilstutzen und die       mantelförmige    Seitenwand des Deckelkörpers  derart nahe aneinander gerückt sind, dass sie  auf der ganzen Höhe des Deckels     bezw.     Kühlraumes ineinander übergehen, so dass  der Kühlraum die Ventilstutzen nicht ganz  umschliesst, was insbesondere auf der dem  Verbrennungsraum zugekehrten Seite der  Stutzen von Nachteil ist.

   Die vorliegende  Erfindung, mit der die Beseitigung des Nach  teils bezweckt wird, besteht darin, dass der  dem Zylinder zugekehrte Teil des Deckel-         körpers    unterhalb des ringförmigen     Anpress-          körpers    derart erweitert ist, dass er nicht nur  bis an die     Deckelbefestigungsschrauben    her  anreicht, sondern auch in der Umgebung  der Ventilstutzen. in die Zwischenräume der       Deckelbefestigungsschrauben    hineinragt, zum  Zwecke, den Kühlraum auf der dem Ver  brennungsraum zugekehrten Seite unter Ein  haltung eines kleinen Durchmessers     für    den       Deckelbefestigungsschraubenkreis    vollständig  um die Ventilstutzen herumführen zu können.

    



  Ein Ausführungsbeispiel des Erfindungs  gegenstands ist auf der Zeichnung darge  stellt.  



       Fig.    1 ist ein Schnitt nach der Linie     I-I     der     Fig.    2, und       Fig.    2 ein Schnitt nach der Linie     II-II     der     Fig.    1.  



       a    ist der die     Öffnung   <I>b</I> für die Kolben  stange, die Stutzen c für die Ventile und  den Kühlraum d enthaltende Deckelkörper  und e. der die Löcher für die     Deckelbefesti-          gungsschrauben    f enthaltende ringförmige       Anpresskörper    des kurbelseitigen Zylinder-           deckels    einer     doppeltwirkenden        Brennkraft-          maschine.     



  Um eine einwandfreie Kühlung der Ven  tilstutzen zu ermöglichen, ist der dem Zy  linder zugekehrte Teil des Deckelkörpers ge  genüber dem vom ringförmigen     Anpresskörper     umschlossenen, vom Zylinder abgekehrten  Teil derart erweitert, dass er nicht nur bis  an die     Deckelbefestigungsschrauben    heran  reicht, sondern in der Umgebung der Ventil  stutzen auch so in die Zwischenräume der       Deckelbefestigungssohrauben    hineinragt, dass  die Ventilstutzen auf der Seite des Verbren  nungsraumes ganz vom Kühlraum umschlossen  werden.  



  g ist die     Kühlwasserzuleitung,    deren Ende  so abgebogen ist, dass sie dem Inhalt des  Kühlraumes zur Erhöhung der Kühlwirkung  eine kreisende Bewegung in Richtung der  eingezeichneten Pfeile erteilt.



      Cylinder cover with cooling space, especially for double-acting internal combustion engines. The invention relates to a cylinder cover with a cooling chamber, in particular for double-acting internal combustion engines, in which a cover body containing the opening for a through piston rod and nozzle for valves is pressed against the cylinder by means of an annular pressure body containing the cover screw holes.

   With the previous cylinder lids of this type, proper cooling of the valve connector is not possible for the reason that the valve connector arranged next to the central piston rod opening and the jacket-shaped side wall of the cover body are moved so close to one another that they respectively over the entire height of the cover. The cooling space merge into one another, so that the cooling space does not completely enclose the valve stub, which is a disadvantage in particular on the side of the stub facing the combustion chamber.

   The present invention, with the aim of eliminating the disadvantage, consists in the fact that the part of the cover body facing the cylinder is widened below the annular pressure body in such a way that it not only extends as far as the cover fastening screws, but also in the vicinity of the valve connector. protrudes into the spaces between the cover fastening screws, for the purpose of being able to completely lead the cooling chamber on the side facing the combustion chamber while maintaining a small diameter for the cover fastening screw circle around the valve connector.

    



  An embodiment of the subject invention is on the drawing provides Darge.



       FIG. 1 is a section along line I-I of FIG. 2, and FIG. 2 is a section along line II-II of FIG.



       a is the opening <I> b </I> for the piston rod, the connector c for the valves and the cooling space d containing the cover body and e. the annular pressing body of the crank-side cylinder cover of a double-acting internal combustion engine containing the holes for the cover fastening screws f.



  In order to enable proper cooling of the Ven tilstutzen, the part of the cover body facing the cylinder is expanded in such a way that it extends not only up to the cover fastening screws, but also in the vicinity of the cylinder, which is enclosed by the annular pressing body and faces away from the cylinder The valve connector also protrudes into the spaces between the cover fastening screws in such a way that the valve connector on the side of the combustion chamber is completely enclosed by the cooling chamber.



  g is the cooling water supply line, the end of which is bent in such a way that it gives the contents of the cooling space a circular movement in the direction of the arrows to increase the cooling effect.
