Description

  

   <Desc/Clms Page number 1> 
 



    Mit Überladuug arbeitende Zweitaktbrennkrat'tnmschine.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
In dem Arbeitszylinder 1 bewegt sich der Arbeitskolben 3, der die Schlitze   a, 6 für   den Aus-und Einlass steuert, wobei die   Einlassschlitze   6 eine grössere Länge besitzen als die   Auslassschlitze   5. Ferner ist 
 EMI2.1 
 Maschine ist folgende :
In Fig. 1 befinden sich beide   Kolben.'3 und 4 noch   in gegenläufiger Bewegung ; der   Arbeitskolben-   beginnt gerade die   Auslassschlitze   5 zu öffnen, während der   Spülkolben   4 die Luft im   Raume : ! weiter   
 EMI2.2 
 in den Arbeitszylinder 1 einströmt.

   In der weiteren Fig. 3 ist der Augenblick veranschaulicht, wenn sich der Spülkolben 4 im Totpunkt befindet, der Arbeitskolben jedoch die   Auspuffschlitze   schon geschlossen hat. Die Schlitze 7 und 8 decken sich in dieser Lage vollkommen und die Luft füllt den Arbeitsraum 1, so lange der Arbeitskolben 3 bei seiner weiteren Aufwärtsbewegung die Öffnungen 6 nicht   abschliesst,   worauf die Verdichtung im Arbeitszylinder eingeleitet wird. In Fig. 4 ist deutlich ersichtlich, dass der Voreilwinkel des Spülkolbens gegenüber dem Arbeitskolben etwas weniger als   180    beträgt. 



   Die Saugventile der Spülpumpe können im Kolben selbst oder im Zylinder angeordnet werden. 



  Die konstruktive Ausführung kann von der dargestellten   selbstverständlich   abweielien. da die Fig. 1 bis 3 das Wesen der Erfindung nur in einem Beispiel schematisch wiedergeben.

    Two-stroke combustion engine working with overload.
 EMI1.1
 

 <Desc / Clms Page number 2>

 
The working piston 3, which controls the slots a, 6 for the outlet and inlet, moves in the working cylinder 1, the inlet slots 6 being longer than the outlet slots 5
 EMI2.1
 Machine is the following:
In Fig. 1, both pistons 3 and 4 are still moving in opposite directions; the working piston is just beginning to open the outlet slots 5, while the flushing piston 4 is the air in the room:! continue
 EMI2.2
 flows into the working cylinder 1.

   In the further FIG. 3, the moment is illustrated when the flushing piston 4 is at dead center, but the working piston has already closed the exhaust ports. The slots 7 and 8 coincide completely in this position and the air fills the working space 1 as long as the working piston 3 does not close the openings 6 during its further upward movement, whereupon the compression in the working cylinder is initiated. In FIG. 4 it can be clearly seen that the advance angle of the flushing piston relative to the working piston is slightly less than 180.



   The suction valves of the irrigation pump can be arranged in the piston itself or in the cylinder.



  The structural design can of course deviate from the one shown. since FIGS. 1 to 3 show the essence of the invention only in one example schematically.
