Description

  

  Ventilsteuerung an     Verbrennungskraftmaschinen.       Die Erfindung bezieht sich auf eine  Ventilsteuerung an     Verbrennungskraftma-          schinen.    Gemäss der Erfindung sind die die  Ventile betätigenden Hebel fliegend und  drehbar auf Zapfen gelagert. Diese Zapfen  können aus den Hebeln herausgezogen wer  den, worauf diese ohne weiteres von den  Ventilen weggenommen werden können.     Da-          durch    wird eine rasche Demontage dieser  Hebel     ermöglicht    und     nahher    können die  Ventile aus dem Zylinderdeckel herausge  nommen werden, ohne dass die Ventilhebel  dabei hindern.

   Die Ventilhebel können     mit-          telst    Gelenkstangen betätigt     werden    und kön  nen bei deren Demontage mit ihnen in     Ver-          bindung    bleiben.  



  In den     Fig.    1 bis 3 der Zeichnung ist ein       Ausführungsbeispiel    des     Erfindungsgegen-          sxandes    dargestellt. Diese zeigt einen Zylin  derdeckel mit je zwei Einlass- und zwei     Aus-          (a        ssventilen.     



       Fig.    1 ist ein     Vertilkalschnitt;        Fig.    2  und     :3    sind Grundrisse desselben. In     Fig.    2    sind alle Hebel in der Betriebslage darge  stellt. In     Fig.    3 sind die untern Hebel demon  tiert.  



  1 ist ein Zylinder einer     Verbrennungs-          kraftmaschine,    2 der Zylinderdeckel, 3, 4, 5,  6 sind Ventileinsätze, in welchen Ventile 7  und 8, 9 und 10 (die beiden ersten nicht dar  gestellt) angeordnet sind. Die Steuerung der  Ventile 7 bis 10 erfolgt durch die Nocken  welle 11 mit den Steuerdaumen 12 und 13,  welche mittelst Rollen 14, 15 und Stossstan  gen 16, 17 auf die Ventilhebel 18, 19 wirken.  Für die Betätigung der von der Steuerwelle  abliegenden Ventile 7 und 9 sind die Ventil  hebel 20g21 vorgesehen, die von den Hebeln  18, 19 mittelst     Mitnehmern    22 betätigt wer  den.  



  Die Ventilhebel 18, 19     bezw.    20, 21 sind  fliegend und drehbar auf einem Zapfen 23       bezw.    24 zu beiden Seiten eines Lagers im  Support 25     bezw.    26 gelagert. Die Zapfen  23, 24 sind so ausgebildet, dass sie in ihrem  Support 25     bezw.    26 axial verschoben und so      aus dem Ventilhebel herausgezogen werden       können,    so dass der     Ventilhebel    nach oben  umgeklappt werden kann, wie dies in     Fig.    1  für den Hebel 18 durch die     punktierte    Stel  lung 181 dargestellt ist.  



  Der Hebel 20 kann dann durch einfache  Drehung in die punktierte Stellung 201     (Fig.     1 und 3) gebracht werden. Damit werden die  beiden     Ventileinsätze    5 und 6 freigelegt, so  dass sie ohne weiteres nach oben herausgezo  gen werden können. Die Erfindung ermög  licht also beim gezeichneten Ausführungs  beispiel eine rasche Demontage der Ventile  ohne weitgehende Demontage der Ventilhebel  und ihrer Verbindung mit den übrigen  Steuerorganen.



  Valve control on internal combustion engines. The invention relates to a valve control on internal combustion engines. According to the invention, the levers actuating the valves are overhung and rotatably mounted on journals. These pins can be pulled out of the levers who the, whereupon they can be easily removed from the valves. This enables these levers to be dismantled quickly, and the valves can be removed from the cylinder cover closer, without the valve levers being an obstacle.

   The valve levers can be operated using articulated rods and can remain connected to them when they are dismantled.



  In FIGS. 1 to 3 of the drawing, an embodiment of the subject of the invention is shown. This shows a cylinder cover with two inlet and two outlet valves each.



       Fig. 1 is a vertical section; Fig. 2 and: 3 are plan views of the same. In Fig. 2, all levers are in the operating position Darge provides. In Fig. 3 the lower levers are demon benefits.



  1 is a cylinder of an internal combustion engine, 2 is the cylinder cover, 3, 4, 5, 6 are valve inserts in which valves 7 and 8, 9 and 10 (the first two not shown) are arranged. The valves 7 to 10 are controlled by the cam shaft 11 with the control thumbs 12 and 13, which act on the valve levers 18, 19 by means of rollers 14, 15 and push rods 16, 17. For the actuation of the remote from the control shaft valves 7 and 9, the valve lever 20g21 are provided, which is operated by the levers 18, 19 by means of drivers 22 who the.



  The valve levers 18, 19 respectively. 20, 21 are cantilevered and rotatable on a pin 23 respectively. 24 respectively on both sides of a camp in the support 25. 26 stored. The pins 23, 24 are designed so that they respectively in their support 25. 26 can be axially displaced and thus pulled out of the valve lever so that the valve lever can be folded upwards, as is shown in Fig. 1 for the lever 18 by the dotted position 181.



  The lever 20 can then be brought into the dotted position 201 (FIGS. 1 and 3) by simple rotation. This exposes the two valve inserts 5 and 6 so that they can easily be pulled out upwards. The invention made light so in the drawn embodiment, for example, a rapid dismantling of the valves without extensive dismantling of the valve lever and their connection with the other control organs.
