    Arbeltuyllnder   für Verbrennungskraftmaschinen. 



   Bei Verbrennungskraftmaschinen erleidet der den   Verbrennungstaum   einschliessende Teil des Zylinders bisweilen sehr hohe Beanspruchungen, denen er besonders dann nicht standzuhalten vermag, wenn die erforderlichen Ventile in der Zylinderwandung angeordnet sind, die Wandung also an diesen Stellen unterbrochen ist. Es lag nun nahe, die Zylinderwandung an der Stelle des Verbrennungsraumes besonders zu verstärken ; diese Massnahme führt jedoch nicht zum Ziele, 
 EMI1.1 
 auf, die sich bald vergrössern und den Zylinder erst recht gefährden. 



   Die Erfindung bezweckt nun, diesen Übelstand zu beseitigen. 



   Auf der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiele veranschaulicht, und zwar zeigt die Figur den oberen Teil des Arbeitszylinders einer stehend angeordneten   Verbrennungskraftmaschine im senkrechten Längsschnitte.   



   Der Arbeitszylinder besteht aus dem oben geschlossenen Zylindermantel A, einem inneren kappenförmigen Zylinderdeckel B, dessen zylindrischer Wandungsteil bis über den Verbrennungsraum herabgezogen ist, und der   Laufbüchse   C für den (nicht dargestellten) Arbeitskolben. Der Zylindermantel   A   und die   Laufbüchse   C bestehen aus   Gusseisen,   während der kappen artige   Deckel B zweckmässig aus besonders widerstandsfähigem Materiale (Schmiedeeisen, Stahl oder dgl. )   hergestellt wird. Der Deckel B besitzt zwei   ringförmige   Flanschen   1J2,     lr   und ist in radialer Richtung mit Spiel in den Mantel   A   eingesetzt.

   Der Ringflansch b3 liegt an einer   Ringfläche   a3 des Zylindermantels   A   an und überträgt während des Betriebes der Maschine die im Innern 
 EMI1.2 
 durch Schrauben E fest verbunden. Die Bauart des Zylinders ist in an sich bekannter Weise so getroffen, dass die   Laufbüchse   C in achsialer Richtung innerhalb des Zylindermantels A zu gleiten vermag. Zur Aufnahme der erforderlichen Ventile F dienen im Zylindermantel A und Deckel B 
 EMI1.3 
 Einwirkung der hohen Drücke und der grossen Wärmeunterschiede ungehindert ausdehnen kann, so dass den Zylinder gefährdende Spannungen nicht leicht auftreten können.

   Dann aber kann der den Verbrennungsraum einschliessende kappenformige Deckel B infolge seiner einfachen Gestaltung aus besonders widerstandsfähigem Materiale durch Giessen, Schmieden oder Pressen hergestellt werden, so dass an den beschriebenen Arbeitszylinder bei verhältnismässig geringen

 von der Aussenwandung vollständig umschlossen ist und sich unabhängig von ihr sowohl in axialer als auch in radialer Richtung frei auszudehnen vermag.

    Arbeltuyllnder for internal combustion engines.



   In internal combustion engines, the part of the cylinder that includes the combustion chamber is subject to very high stresses, which it cannot withstand especially when the necessary valves are arranged in the cylinder wall, i.e. the wall is interrupted at these points. The obvious thing to do was to strengthen the cylinder wall at the point of the combustion chamber. However, this measure does not lead to the goal
 EMI1.1
 which soon enlarge and endanger the cylinder even more.



   The invention now aims to eliminate this drawback.



   In the drawing, the subject matter of the invention is illustrated in an exemplary embodiment, specifically the figure shows the upper part of the working cylinder of an upright internal combustion engine in vertical longitudinal section.



   The working cylinder consists of the cylinder jacket A, closed at the top, an inner cap-shaped cylinder cover B, the cylindrical wall part of which is pulled down over the combustion chamber, and the liner C for the working piston (not shown). The cylinder jacket A and the liner C are made of cast iron, while the cap-like cover B is expediently made of particularly resistant materials (wrought iron, steel or the like). The cover B has two annular flanges 1J2, 1r and is inserted into the jacket A with play in the radial direction.

   The annular flange b3 rests on an annular surface a3 of the cylinder jacket A and transfers the inside during operation of the machine
 EMI1.2
 firmly connected by screws E. The design of the cylinder is made in a manner known per se so that the liner C is able to slide in the axial direction within the cylinder jacket A. The required valves F are used in the cylinder jacket A and cover B.
 EMI1.3
 Can expand unhindered under the effect of the high pressures and the large heat differences, so that stresses that endanger the cylinder cannot easily occur.

   Then, however, the cap-shaped cover B enclosing the combustion chamber can be produced from particularly resistant materials by casting, forging or pressing due to its simple design, so that the working cylinder described can be used at relatively low levels
 EMI1.4
   PATENT CLAIMS:
1. Working cylinder for internal combustion engines with separate outer and inner walls, characterized in that the combustion chamber is
 EMI1.5
 is completely enclosed by the outer wall and independently of it is able to expand freely both in the axial and in the radial direction.
