 die die Kanäle mit der   Kammer B verbinden,   aber von dem Kolbenfortsatz bedeckt bleiben, bis er das Ende des   Rückwärtshubes     erreicht. Dann strömt   die Luft ein und füllt die Kammer   BI     und das Rohr J, das die Kammer an irgend einem geeigneten Punkt mit dem Zylinder B durch ein Rückschlagventil, Jl verbindet.

   Bei dem Abwärts- oder Arbeitshub des Kolbens wird die Luftfüllung in der Kammer BI und dem Rohr J verdichtet, sobald der Kolbenfortsatz die Öffnungenl1 verschliesst und gegen Ende des Arbeitshubes geht die verdichtete Ladung durch   das Ventil   Jl   in den Zylinder über, wenn der Druck der Spülfüllung grösser geworden ist, als der im Zylinder, so dass die Spülfüllung in den Zylinder einströmt und die Verbrennungsrückstände durch die Auspufföffnungen B4 hinausspült. 



   Bei der Maschine nach der Erfindung kann die bei solchen Maschinen gewöhnlich angewendete Art der Schmierung ohneweiteres benützt werden, da das Kurbelgehäuse nicht als Verdichtungskammer verwendet wird. Der Kolben A kann mit seitlichen Schmierlöchern   16   (Fig. 1) ausgestattet sein, durch die das Schmiermittel an die Reibflächen gelangen kann. 



   PATENT-ANSPRÜCHE : 
1. Zweitaktexplosionskraftmaschine mit auf einer feststehenden Hülse gleitendem Stufenkolben, dadurch gekennzeichnet, dass der Raum, in dem der Ringkolben arbeitet, sowohl als Ladepumpe als auch als   Spülluftpumpe   dient und zu diesem Zwecke an beiden Enden mit dem Arbeitszylinder verbunden ist.

 which connect the channels to chamber B, but remain covered by the piston extension until it reaches the end of the return stroke. Then the air flows in and fills the chamber BI and the tube J, which connects the chamber at any suitable point with the cylinder B through a check valve, Jl.

   During the downward or working stroke of the piston, the air charge in the chamber BI and the tube J is compressed as soon as the piston extension closes the openingsl1 and towards the end of the working stroke the compressed charge passes through the valve Jl into the cylinder when the pressure of the flushing charge has become larger than the one in the cylinder, so that the flushing charge flows into the cylinder and flushes the combustion residues out through the exhaust ports B4.



   In the machine according to the invention, the type of lubrication usually used in such machines can be used without further ado, since the crankcase is not used as a compression chamber. The piston A can be equipped with lateral lubrication holes 16 (FIG. 1) through which the lubricant can reach the friction surfaces.



   PATENT CLAIMS:
1. Two-stroke explosion engine with stepped piston sliding on a stationary sleeve, characterized in that the space in which the annular piston works serves both as a charge pump and as a scavenging air pump and is connected to the working cylinder at both ends for this purpose.

 

Claims (1)

2. Zweitaktexplosionskraftmaschine nach Anspruch 1, dadurch gekennzeichnet, dass mittels eines Schiebers fi2), der den Raum, in dem der Ringkolben (A) arbeitet, mit der freien Luft oder dem BrennstoSzufuhrkanal (D) verbindet, die Erössnungsdauer des Gemischeinlassventils (C1) und damit auch die Länge des wirksamen Verdichtungsbubes des Ringkolbens verändert werden kann. 2. Two-stroke explosion engine according to claim 1, characterized in that by means of a slide fi2) which connects the space in which the annular piston (A) works with the free air or the fuel supply channel (D), the opening time of the mixture inlet valve (C1) and so that the length of the effective compression stroke of the annular piston can also be changed.
