Description

  

      Arbeitszylinder,    insbesondere für     doppeltwirkende        Verbrennungskraftmasehinen.       Die Erfindung     betrifft    einen Arbeitszylin  der, insbesondere für     doppeltwirkende        Ver-          brennungskraftmaschinen.    Dieser besitzt ge  mäss der     Erfindung    einen Einsatzzylinder, der  nur soweit, als er von den Kolbenringen be  strichen wird, aus Gusseisen hergestellt ist,  während der übrige Teil aus einem schmied  baren Eisen, zum Beispiel     Schmiedeisen    oder  Stahl besteht.  



  Als Ausführungsbeispiel des Erfindungs  gegenstandes ist auf der Zeichnung der un  tere Teil des Zylinders einer vertikalen dop  pelwirkenden     Verbrennungskraftmaschine    zur  Darstellung gebracht.  



       a    ist der     Arbeitskolben,    b die Kolben  stange, c der die Stopfbüchse enthaltende  Zylinderdeckel, d der Zylindermantel, e der  Einsatzzylinder, f der Verbrennungsraum und  g die Öffnung für ein durch den Einsatz  zylinder in den     Verbrennungsraum    einmün  dendes     Einlassorgan.    Der Einsatzzylinder ist  mehrteilig ausgeführt und nur der von den  Kolbenringen i bestrichene Teil     e1    ist aus  Gusseisen hergestellt, während der nicht be-         strichene    Teil     e2    aus zum Beispiel Schmied  eisen besteht.

   Dadurch wird unter Beibehal  tung einer     gusseisernen    Lauffläche für den  Kolben ermöglicht,     erstens    die Mündungen  der in den Verbrennungsraum eingeführten Or  gane, zum Beispiel der Steuerorgane, in zäheres  Material als     Grusseisen    zu verlegen und zwei  tens die Wandstärke in dem den Verbren  nungsraum umgebenden Teil des Einsatz  zylinders zu verkleinern, damit die Wärme  spannungen weniger gefährlich werden.



      Working cylinder, especially for double-acting internal combustion engines. The invention relates to a Arbeitszylin, in particular for double-acting internal combustion engines. According to the invention, this has an insert cylinder which is made of cast iron only to the extent that it is coated by the piston rings, while the remaining part consists of a forging iron, for example wrought iron or steel.



  As an embodiment of the subject invention, the lower part of the cylinder of a vertical double acting internal combustion engine is shown in the drawing.



       a is the working piston, b the piston rod, c the cylinder cover containing the stuffing box, d the cylinder jacket, e the insert cylinder, f the combustion chamber and g the opening for an inlet member opening into the combustion chamber through the insert cylinder. The insert cylinder is constructed in several parts and only the part e1 coated by the piston rings i is made of cast iron, while the uncoated part e2 consists of, for example, wrought iron.

   This makes it possible, while maintaining a cast-iron running surface for the piston, firstly to relocate the mouths of the organs introduced into the combustion chamber, for example the control organs, in a tougher material than cast iron and, secondly, to relocate the wall thickness in the part of the insert surrounding the combustion chamber to reduce the size of the cylinder so that the thermal stresses are less dangerous.
