Description
Drehkolbenbrennkraftmaschine mit in der Kolbentrommel geführten Schieberkolben Ven Gegenstand der Erfindung bildet eine Drehkolbenbrennkraftmaschine mit Schieberkolben in der Kolbentrommel. Bei der Bewegung der Schieberkolben in den Führungsschlitzen der Kolbentrommel entsteht bisher in den Führungsschlitzen abwechselnd Über-oder Unterdruck, zu dessen Bildung ein Teil der in der Maschine erzeugten Energie aufgebraucht wird. Dieser Teil kann für die Energieabgabe nicht völlig zurückgewonnen werden.Rotary piston internal combustion engine with slide piston guided in the piston drum The invention relates to a rotary piston internal combustion engine with a slide piston in the piston drum. When moving the spool in the guide slots the piston drum has hitherto been created in the guide slots alternately over or over Negative pressure, for which part of the energy generated in the machine is used up will. This part cannot be fully recovered for the energy output.
Die Erfindung bezweckt nun, eine Vorrichtung zu schaffen, durch die eine unnötige Energievernichtung in den Führungsschlitzen vermieden wird. Das geschieht dadurch, daß erfindungsgemäß der in den Führungsschlitzen der Schieberkolben entstehende Über-oder Unterdruck durch Entlastungskanäle ausgeglichen wird und die Entlastungskanäle durch in der Welle angeordnete Nuten mit der Außenluft in Verbindung stehen. Durch diese Nuten werden auch Gase, die infolge Undichtigkeiten aus den Verdichtungs- und Verbrennungskammern nach den Führungsschlitzen entweichen, nach außen abgeführt.The invention now aims to provide a device through which unnecessary energy dissipation in the guide slots is avoided. This happens in that, according to the invention, the resulting in the guide slots of the slide piston Over- or underpressure is compensated by relief channels and the relief channels are in communication with the outside air through grooves arranged in the shaft. By these grooves are also gases that as a result of leaks from the compression and combustion chambers escape after the guide slots, discharged to the outside.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes im Querschnitt. Von den Schieberkolben f, zwischen denen sich fortlaufend die bekannten vier Takte, Ansaugen (Raum g), Verdichten (Raum k), Verbrennen (Raum x), Auspuffen (Raum p), abspielen, sind zwei Schieberkolben in die Kolbentrommel a zurückgeschoben und die anderen beiden aus der Kolbentrommel vorgeschoben dargestellt. Zum Ausgleich des bei der Hinundherbewegung der Schieberkolben in den Führungsschlitzen 39 entstehenden Über- oder Unterdrucks sind in der Kolbentrommel die .gestrichelt angedeuteten runden Entlastungskanäle d vorhanden, die die Führungsschlitze miteinander verbinden und nach den Arbeitsräumen zu durch Deckel abgeschlossen sind. 21 ist die Welle der Kolbentrommel. Sie ist am andern Ende, wie bei 22 punktiert angedeutet, verdickt und enthält, durch die Führungsschlitze 39 sichtbar, die die Verbindung mit der Außenluft herstellenden Nuten n. y deutet die Zündkerzenbohrung, j3 die Gaszuleitungs- und j2 die Gasableitungsöffnung im Zylindergehäuse an.The drawing shows an exemplary embodiment of the subject matter of the invention in cross section. Two slide pistons are pushed back into the piston drum a from the slide piston f, between which the known four strokes, intake (space g), compression (space k), combustion (space x), exhaust (space p), continuously take place the other two shown advanced from the piston barrel. To compensate for the overpressure or underpressure that occurs in the guide slots 39 when the spool moves back and forth, the round relief channels d indicated by dashed lines are provided in the piston drum, which connect the guide slots to one another and are closed off by covers after the working spaces. 21 is the shaft of the piston drum. At the other end, as indicated by dotted lines at 22, it is thickened and contains, through the guide slots 39, the grooves n that establish the connection with the outside air.
