Description

  

  Zylinder für     doppeltwirkende        Zweitaktverbrennungskraftmasehinen.       Die Erfindung bezieht sich auf einen  Zylinder für     doppeltwirkende        Zweitaktver-          brennungskraftmaschinen    und besteht darin,  dass ein Zylinderdeckel als Rotationskörper  ausgebildet, mit einem zentralen Einsatz,  zum Beispiel für Ventile, versehen und ver  mittelst ausserhalb des Zylinderdeckels an  geordneter Schrauben zwischen einem über  <B>den</B> Zylinderdeckel gezogenen und denselben  übergreifenden Zylindermantel und einem  Zylindereinsatz eingespannt ist, zum Zweck,  schwere Verschraubungen im Zylinderdeckel  zu umgehen.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist auf der Zeichnung dargestellt.  Der als Rotationskörper ausgebildete Zy  linderdeckel 1 ist mit einem zentralen Ein  satz 2 versehen, welcher zur Aufnahme der  Ventile, z. B. der     Einspritz-    und     Auslassventile,     dient. Der Zylinderdeckel ist zwischen dem  Zylindermantel 3 und dem Zylindereinsatz 4  eingespannt. Der Zylindermantel ist mit dem  Zylindereinsatz vermittelst der Schrauben 5  verbunden. Beide sind in der Zone der Ein-         lassschlitze    6 und der     Auslassschlitze    7 unter  teilt und durch den Zylindereinsatz zentriert.

    Die Verbindung des untern und obern Zylin  derteils erfolgt durch Schrauben 8, so dass  nach Lösung dieser Schrauben der Ausbau  des obern Zylinderteils als Ganzes ohne  Lösung der Dichtungen für die Wasserräume  9 des Zylinderdeckels und 10 des Zylinders  möglich ist. Die Schrauben 5 sind ausserhalb  des Zylinderdeckels 1 angeordnet, so dass  derselbe nicht durchbrochen wird.  



  Der beschriebene Zylinder hat den Vorteil,  dass die bisher verwendeten, auf Zug bean  spruchten, schweren Deckelschrauben, die  durch ihre Zahl und Dicke die Herstellung  des Zylinderdeckels, sowie dessen Verbindung  mit dem Zylindermantel wesentlich er  schwerten und verteuerten, überflüssig werden.  An ihrer Stelle wird der Deckel zwischen  dem Mantel und dem Zylindereinsatz fest  gehalten. Die Schrauben 5 werden durch  die auf den Zylinderdeckel wirkenden Kräfte  nicht beansprucht. Sie haben nur den Dich  tungsdruck zwischen der Laufbüchse und      dem Zylinderdeckel aufzunehmen und den  Zusammenhalt der aus Deckel, Mantel und  Laufbüchse bestehenden Zylinderhälfte auf  recht zu erhalten. Der Deckel, der überdies  kleiner ist als sonst, überträgt die auf ihn  ausgeübten Kräfte unmittelbar auf den Zy  lindermantel.

   Ferner ist beim beschriebenen  Zylinder eine durchgehende Bearbeitung des  Zylindereinsatzes möglich.



  Cylinders for double-acting two-stroke internal combustion engines. The invention relates to a cylinder for double-acting two-stroke internal combustion engines and consists in the fact that a cylinder cover is designed as a body of revolution, provided with a central insert, for example for valves, and arranged outside the cylinder cover on ordered screws between a </B> Cylinder cover pulled and the same overlapping cylinder jacket and a cylinder insert is clamped for the purpose of avoiding heavy screw connections in the cylinder cover.



  An embodiment of the subject invention is shown in the drawing. The cylinder cover designed as a rotation body Zy 1 is provided with a central A set 2, which is used to accommodate the valves, for. B. the injection and exhaust valves, is used. The cylinder cover is clamped between the cylinder jacket 3 and the cylinder insert 4. The cylinder jacket is connected to the cylinder insert by means of the screws 5. Both are in the zone of the inlet slots 6 and the outlet slots 7 and are centered by the cylinder insert.

    The connection of the lower and upper cylinder part is done by screws 8, so that after loosening these screws the expansion of the upper cylinder part as a whole without loosening the seals for the water spaces 9 of the cylinder cover and 10 of the cylinder is possible. The screws 5 are arranged outside the cylinder cover 1 so that the same is not broken.



  The cylinder described has the advantage that the previously used, stressed on train bean, heavy cover screws, which by their number and thickness made the production of the cylinder cover, as well as its connection with the cylinder jacket significantly he difficult and expensive, are superfluous. In their place, the cover is held firmly between the jacket and the cylinder insert. The screws 5 are not stressed by the forces acting on the cylinder cover. You only have to absorb the sealing pressure between the liner and the cylinder cover and to maintain the cohesion of the cylinder half consisting of the cover, jacket and liner. The lid, which is also smaller than usual, transfers the forces exerted on it directly to the cylinder jacket.

   Furthermore, continuous machining of the cylinder insert is possible with the cylinder described.
