Description
Drehkolbenkraftmaschine, insbesondere Drehkolbenbrennkraftmaschine Die ,Erfindung betrifft eine Verbesserung der bekannten Drehkolbenkraftmaschinen, ins.-besondere Drehkölbenbrennkraftmaschinen, bei denen in einem Ringzylinder ein oder mehrere Kolben stets in gleicher Richtung umlaufen. Um einen Arbeitsraum für das Betriebsgas zu schaffen, ist es bekannt, schwingend gelagerte Widerlager anzuordnen, die in den Ringzylinder einschwenken und dadurch zwischen sich und der hinteren Kolbenfläche einen Teil des kingzylinderraums zum Arbeitsraum machen. -Um - Arbeitsverluste zu vermeiden, insbesondere dann, wenn es sich um eine mi.t hohem Verbrennungsdruck arbeitende Maschine handelt, wird 'erfindungsgemäß vorgeschlagen, das Widerlager in. zu dessen Schwingachse radialer Richtung beweglich anzuordnen. Auf diese Weise läßt sich das in den Ringzylinderraum eingeschwenkte Widerlager gegen Dichtungsflächen im Maschinengehäuse andrücken, so daß eine sehr gute Abdichtung des Arbeitsraumes erreicht ist.Rotary piston engine, in particular rotary piston internal combustion engine The invention relates to an improvement of the known rotary piston engines, in particular rotary piston internal combustion engines, in which a ring cylinder is a or several pistons always rotate in the same direction. To have a work space for To create the operating gas, it is known to arrange swinging abutments, which pivot into the ring cylinder and thereby between itself and the rear Make the piston area a part of the king cylinder space into the working space. -To - work losses to be avoided, especially if the combustion pressure is very high working machine is, is' proposed according to the invention, the abutment in. To be arranged movable in the radial direction in relation to its oscillation axis. In this way the abutment pivoted into the annular cylinder space can be moved against sealing surfaces Press into the machine housing, so that a very good seal of the working area is reached.
Die radiale Bewegung des Widerlagers erfolgt entgegen der Richtung des Betriebsmitteldrucks, und das Widerlager ist mit Spiel auf seiner Drehachse gelagert. Dieses Spiel gestattet die zum Abdichten erforderliche radiale Bewegung, die beispielsweise durch Exzenter hervorgerufen wird. Vorzugsweise werden die beiden Bewegungen des Widerlagers, nämlich,die Schwing-und die Rädialbewegung von Nockenscheiben aus gesteuert, die von der Maschinenwelle in Drehung.versetzt werden.The radial movement of the abutment takes place in the opposite direction of the operating fluid pressure, and the abutment is with play on its axis of rotation stored. This clearance allows the radial movement required for sealing, which is caused, for example, by an eccentric. Preferably the two Movements of the abutment, namely, the oscillating and the radial movement of cam disks which are set in rotation by the machine shaft.
In der Zeichnung ist ein Ausführungsbeispiel der Maschine veranschaulicht, und zwar handelt es sich um eine Maschine mit einander gegenüberliegend angeordneten Widerlagern. Die linke Hälfte der Figur zeigt die Maschine in einem mittleren Querschnitt, während die rechte Hälfte der Figur die Maschine in Ansicht und nur teilweise im Schnitt gezeichnet darstellt. In die Zeichnung sind nur die zur Erläuterung des Erfindungsgegenstandes in Frage kommenden Teile aufgenommen worden.In the drawing, an embodiment of the machine is illustrated, namely, it is a machine with oppositely arranged Abutments. The left half of the figure shows the machine in a middle cross-section, while the right half of the figure shows the machine in view and only partially in Section drawn represents. Only those for explanation of the Subject matter of the invention in question have been included.
Das Maschinengehäuse besteht beispielsweise aus einem vorderen Teil i und einem hinteren Teil 2. In diese Gehäuseteile ist der Ringzylinder 3 eingearbeitet, in dem Kolben q. umlaufen. Die Kolben q. sind von radialen Armen 5 getragen, die auf der zentralen Maschinenwelle 6 befestigt sind. In entsprechenden Aussparungen 7 des Gehäuses i, 2 sind die Widerlagerhebel 8 auf Achsen 9 drehbar gelagert. Um außer der Schwingbewegung des Widerlagers 8 auch dessen radiale Bewegung zu ermöglichen, ist auf der Schwingachse 9 ein Gleitschein io befestigt, der in einem beispielsweise rechteckigen Ausschnitt z i des Widerlagers 8 angeordnet ist. Hierbei ist die Anordnung so getroffen, daß, wie aus der linken Hälfte der Figur ersichtlich, zwi,#; schen Wi.derlager und Gleitstein io das-mit a bezeichnete Spiel vorhanden ist.The machine housing consists, for example, of a front part i and a rear part 2. The ring cylinder 3 is incorporated into these housing parts, in the piston q. circulate. The pistons q. are carried by radial arms 5, the are attached to the central machine shaft 6. In corresponding recesses 7 of the housing 1, 2, the abutment levers 8 are rotatably mounted on axes 9. Around in addition to the oscillating movement of the abutment 8, also to enable its radial movement, a sliding slip io is attached to the swing axis 9, which in a for example rectangular cutout z i of the abutment 8 is arranged. Here the arrangement is made so that, as can be seen from the left half of the figure, zwi, #; between the anti-friction bearing and sliding block io the game designated with a is present is.
Die radiale Bewegung der Widerlager 8' er-' folgt durch Achsen 12, die zu einem Exzenter' 12' ausgebildet sind. Das Exzenter 12' arbeitet beispielsweise mit dem Umfang des Widerlagers 8 zusammen, wie aus der linken =Hälfte der Figur ersichtlich.The radial movement of the abutments 8 'takes place through axes 12, which are designed as an eccentric '12'. The eccentric 12 'works for example with the circumference of the abutment 8 together, as from the left = half of the figure evident.
Auf der angetriebenen Welle 16 ist eine Nockenscheibe 13 befestigt, deren Nocken 14 mit den Hebeln 15, 16 zusammenarbeiten. Die Hebel 15, 16 sind um einen -mit dem Maschinengehäuse fest verbundenen Bolzen 17 drehbar. Außen auf den Achseng, 12 sind die Hebel 18, i9 befestigt, die durch Druckstangen 2o, 21 mit den Hebeln 15, 16 gelenkig verbunden sind, wie aus der rechten Hälfte der Figur ersichtlich. Eine Schraubenfeder 22 wirkt mittels einer Zugstange 23 derart auf .den Hebel i9 und damit auf die Achse 9 ein, daß sich das Widerlager 8 stets in seiner in der Zeichnung dargestellten eingeschwenk-. ten Lage befindet.A cam disk 13 is attached to the driven shaft 16, the cams 14 of which work together with the levers 15, 16. The levers 15, 16 are rotatable about a bolt 17 firmly connected to the machine housing. On the outside of the axles 12, the levers 18, 19 are attached, which are articulated to the levers 15, 16 by push rods 2o, 21, as can be seen in the right half of the figure. A helical spring 22 acts by means of a pull rod 23 on the lever i9 and thus on the axis 9 that the abutment 8 is always pivoted in its position shown in the drawing. ten location.
Durch die umlaufenden Nocken 14 wird das Widerlager in dem Augenblick aus dem Ringzylinder zurückgezogen, in dem der Kolben 4 ,die Widerlagerstelle durchläuft. Ist das geschehen; - so schwenkt das Wi.derlager wieder in seine in der Zeichnung dargestellten Lage'ein, und gleichzeitig wird unter Vermittlung der Hebel 16, 18 eine Verdrehung der Achse 12 vorgenommen derart, daß das Exzenter 12' die radiale Verschiebung des Widerlagers 8 bewirkt, wobei das Spiel a überbrückt wird. Infolge dieser radialen Bewegung wird das Widerlager 8 gut abdichtend gegen die Anliegeflächen 24 im Maschinengehäuse angepreßt. Ist -der Nocken 14 unter dem Hebel 16 durchzelaufen, dann hört die radiale Andrückbewegung auf, und das Widerlager kann beim Durchlaufen des .nächsten Kolbens wieder seine Drehbewegung 'äusführen.By rotating cams 14, the abutment is at the moment withdrawn from the ring cylinder in which the piston 4 passes through the abutment point. Has that happened? - so the pivot bearing swivels back into its in the drawing Position'ein shown, and at the same time with the intermediation of the levers 16, 18 a rotation of the axis 12 made such that the eccentric 12 'is the radial Displacement of the abutment 8 causes, the game a is bridged. As a result this radial movement, the abutment 8 is a good seal against the contact surfaces 24 pressed in the machine housing. If the cam 14 has passed under the lever 16, then the radial pressing movement stops, and the abutment can go through of the "next piston" perform its rotary motion again.
..:'Zwecks weiterer Abdichtung des Arbeitsrä.umes und zwecks Abdichtung zwischen @Widerlager und Kolbentrommel kann das Widerlager noch mit einem Kolbenring 25 versehen- sein. Dieser Kolbenring hat den weiteren Vorteil, daß sich das Widerlager federnd am Kolbentrommelumfang anlegt...: 'For the purpose of further sealing the work area and for the purpose of sealing between the abutment and the piston drum, the abutment can still be fitted with a piston ring 25 be provided. This piston ring has the further advantage that the abutment resiliently applied to the circumference of the piston drum.
