Description

Rotationskolben-Brennkraftmaschine in Mehrscheibenausführung, insbesondere mit Schlupfeingriff" Die Erfindung bezieht sich auf eine Rotationskolben-Brennkraftmaschine in Mehrscheibenausführung, insbesondere mit Schlupfeingriff, mit für jede Scheibe einem Mantel, der einen Trochoidenraum umschließt, mit einer im Mantel angeordneten Zündkerze und einem von der Zündkerze in den Trochoidenraum führenden Schußkanal, in den in unmittelbarer Nähe der Zündkerze eine Leitung mündet. Rotary piston internal combustion engine in multi-disc design, in particular with slip engagement "The invention relates to a rotary piston internal combustion engine in multi-disc design, especially with slip engagement, with for each disc a mantle enclosing a trochoid space, with one arranged in the mantle Spark plug and a firing channel leading from the spark plug into the trochoid space, into which a line opens in the immediate vicinity of the spark plug.

Es wurde bei Rotationskolben-Brennkraftmaschinen der genannten Art bereits vorgeschlagen, die in den Schußkanal mündende Leitung an eine Druckluftquelle anzuschließen,zu Beginn der Verdichtung Luft durch den Schußkanal in den Trochoidenraum zu blasen und diesen von VerbrennungsrUckständen zu reinigen. Diese Vorrichtung hat die Nachteile, daß eine gesonderte Druckluftquelle vorgesehen werden muß und daß sowohl im Schußkanal wie in dem Teil der Verdichtungskammer, der während der Zündung der Zündkerze vorgelagert ist, sich Luft oder brennstoffarmes Brennstoff-Luftgemisch befindet, so daß dessen Zündung nicht oder nur schwer möglich ist.It was used in rotary piston internal combustion engines of the type mentioned already proposed, the line opening into the firing channel to a compressed air source to connect, at the beginning of the compression air through the firing channel into the trochoid space to blow and to clean it of combustion residues. This device has the disadvantages that a separate compressed air source must be provided and that both in the firing channel as in that part of the compression chamber which is during the Ignition of the spark plug is upstream, air or fuel-poor fuel-air mixture is located, so that its ignition is not possible or only with difficulty.

Der Erfindung liegt die Aufagbe zugrunde, eine Vorrichtung zu schaffen, die die genannten Nachteile vermeidet. Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Leitung mit der Verdichtungskammer einer anderen Scheibe verbunden ist, wobei in der Leitung ein Ventil angeordnet ist, das bei einem gegenüber der Verdichtungskammer der anderen Scheibe höheren Druck im Schußkanal schließt.The invention is based on the task of creating a device which avoids the disadvantages mentioned. According to the invention, the object is thereby achieved solved that the line connected to the compression chamber of another disc is, wherein a valve is arranged in the line, the opposite of the Compression chamber of the other disc closes higher pressure in the firing channel.

Bei der erfindungsgemäßen Vorrichtung wird einer Verdichtungskommer mit höherem Druck als im Schußkanal Brennstoff-Luftgemisch entnommen und durch den Schußkanal in den Trochoidenr@um geblasen. Damit werden nicht @ur die Zündkerze und der Schußkanal von @@rbrennungsrückständen gereinigt, sondern der Zündkerze auch ein zündwilliges Gemisch vorgelagert. Außerdem wird eine an sich bekannte für die Gemischaufbereitung günstige Störströmung in der Verdichtungskammer erreicht. Das in der Leitung angeordnete Ventil verhindert ein Pückströmen von Verbrennungsgasen von dem Schußkanal in die Verdichtungskammer der anderen Scheibe.In the device according to the invention, a compaction comer With a higher pressure than in the firing channel, the fuel-air mixture is removed and through the Shot channel in the Trochoidenr @ blown around. This will not @ur the spark plug and the firing channel cleaned of combustion residues, but the spark plug also an ignitable mixture upstream. It is also known per se for the mixture preparation achieves favorable disturbance flow in the compression chamber. The valve arranged in the line prevents combustion gases from flowing back from the shot channel into the compression chamber of the other disc.
