  Zylinder mit Kühlmantel von doppelt wirkenden Brennkraftmaschinen. 



   Bei doppelt wirkenden Brennkraftmaschinen, insbesondere Zweitaktmaschinen grosser Leistung, ist es nötig, dass das die Zylinderlaufbüehse   umspülende   Kühlwasser so   geführt   wird, dass beide Ver-   brennungsräume gleichmässig gekühlt   werden. 



   Zu diesem Zweck ist schon vorgeschlagen worden, im Kühlmantel eine Anzahl Rippen anzuordnen, die dem Wasser einen bestimmten Weg vorschreiben. Hiebei wurde jedoch das Kühlmittel unten in den Zylinder eingeführt, worauf es nacheinander den unteren Zylinderdeckel, den Kühlmantel in seiner 
 EMI1.1 
 Rippen fand jedoch stets nur in   nächster   Nähe der Verbrennungsräume statt. 



   Diese Kühlmittelführung hat den Nachteil, dass das   Wärmegefälle   zwischen dem Kühlmittel und den Zylinderwänden in den einzelnen Zylinderteilen verschieden ist, so dass diese Teile verschieden stark gekühlt werden. 



   Die vorliegende Erfindung vermeidet diesen Nachteil dadurch, dass das Kühlmittel einer Stelle des Zylinders zugeführt wird, die die geringste Wärme aufweist, Dies ist bei doppelt wirkenden Brennkraftmaschine der zwischen beiden Verbrennungsräumen liegende mittlere Zylinderteil. 



   Von hier aus strömt dann das Kühlmittel, das getrennt oder gemeinsam für beide Zylinderseiten in das   Zylindermittelstück   eingeführt werden kann, gleichmässig nach beiden Verbrennungsräumen hin ab, so dass auf beiden Zylinderseiten in allen entsprechenden Teilen gleiches Wärmegefälle zwischen dem Kühlmittel und den. Zylinderwänden vorhanden ist, und gleiche Kühlwirkungen erzielt werden. 



   Das an den Zylinderenden entströmende Kühlmittel kann noch vorteilhaft zur Kühlung der Zylinderdeckel verwendet werden. 



   Die Erfindung ist in einem Ausführungsbeispiel in der Zeichnung veranschaulicht, in welcher Fig. 1 den Längsschnitt eines doppelt wirkenden Zylinders und Fig. 2 die innere Abwicklung des Kühlmantels nach der Linie   A-B   der Fig 1 darstellen. 



   In Fig. 1 bezeichnet a die obere, b die untere Laufbüchse, c den oberen, d den unteren Kühlmantel und e das Zylindermittelstück. Das Kühlmittel tritt durch die Stutzen t, p in die Kammern g, q des Zylindermittelstückes e ein und teilt sich in die Einzelströme h, i. Die Einzelströme h fliessen durch die Kanäle k in die Kammer   l   und von dort aus weiter durch die Ringkammern m bis zum oberen Austritt n. 



   Die Ströme i dagegen fliessen durch die Kanäle o in   die Kammer r   und von hier weiter durch die 
 EMI1.2 
 wird durch Umführungsrohre in die nicht gezeichneten oberen und unteren Zylinderdeckel geleitet. 



  Von den Zylinderdeekeln fliesst das Kühlmittel in eine   Sammelleitung.

  Cylinders with cooling jackets from double-acting internal combustion engines.



   In the case of double-acting internal combustion engines, in particular two-stroke engines with high output, it is necessary that the cooling water flowing around the cylinder liner is guided in such a way that both combustion chambers are cooled evenly.



   For this purpose, it has already been proposed to arrange a number of ribs in the cooling jacket that dictate a certain path for the water. Here, however, the coolant was introduced into the bottom of the cylinder, whereupon it successively the lower cylinder cover, the cooling jacket in its
 EMI1.1
 However, ribs only took place in the immediate vicinity of the combustion chambers.



   This coolant flow has the disadvantage that the heat gradient between the coolant and the cylinder walls is different in the individual cylinder parts, so that these parts are cooled to different degrees.



   The present invention avoids this disadvantage in that the coolant is fed to a point on the cylinder that has the least amount of heat. In the case of a double-acting internal combustion engine, this is the middle cylinder part located between the two combustion chambers.



   From here, the coolant, which can be introduced separately or jointly into the cylinder center piece for both cylinder sides, flows evenly to both combustion chambers, so that the same heat gradient between the coolant and the. Cylinder walls are present, and the same cooling effects can be achieved.



   The coolant flowing out at the cylinder ends can also advantageously be used to cool the cylinder cover.



   The invention is illustrated in an exemplary embodiment in the drawing, in which FIG. 1 shows the longitudinal section of a double-acting cylinder and FIG. 2 shows the inner development of the cooling jacket along the line A-B of FIG.



   In Fig. 1, a denotes the upper, b the lower liner, c the upper, d the lower cooling jacket and e the cylinder center piece. The coolant enters the chambers g, q of the cylinder center piece e through the connection t, p and divides into the individual flows h, i. The individual streams h flow through the channels k into the chamber l and from there on through the annular chambers m to the upper outlet n.



   The currents i, however, flow through the channels o into the chamber r and from here on through the
 EMI1.2
 is routed through bypass pipes into the upper and lower cylinder covers (not shown).



  The coolant flows from the cylinder covers into a collecting line.
