Description

Die Erfindung bezieht sich auf eine innenachsige Rotationskolben-Brennkraftmaschine mit einem Mantel, der in radialer Richtung nach innen sich erstreckende Trennwände aufweist, die Arbeitskammern begrenzen und mit zwei an einer Nabe exzentrisch angeordneten, drehbar gelagerten Kolben, die achsnahe und achsferne Zonen aufweisen.The invention relates to an internal-axis rotary piston internal combustion engine with a jacket, the partition walls extending inward in the radial direction has, limit the working chambers and with two eccentrically arranged on a hub, rotatably mounted pistons, which have zones close to and away from the axis.

Soweit solche Maschinen bereits bekannt geworden sind, z. B. durch die USA.-Patentschrift 2 478 924, haben jedoch die Arbeitskammern eine komplizierte Form, und es entstehen zerklüftete Verbrennungs-und Expansionsräume. Aufgabe der Erfindung ist es nun, eine solche Maschine so auszubilden, daß die Form der Arbeitskammern möglichst einfach wird und gleichzeitig dafür zu sorgen, daß bei einer für den Wirkungsgrad möglichst günstigen Ausbildung der Kolben gleichzeitig eine hinreichende Dichtung bei möglichst geringer Reibung erzielt wird.As far as such machines are already known, z. B. by U.S. Patent 2,478,924, however, the working chambers are complicated Form, and jagged combustion and expansion spaces are created. Task of The invention is now to design such a machine so that the shape of the working chambers is as simple as possible and at the same time to ensure that one for the efficiency as favorable as possible design of the piston at the same time an adequate seal is achieved with the lowest possible friction.

Diese Aufgabe wird dadurch gelöst, daß jeder Kolben im Querschnitt doppel-T-förmig ausgebildet ist, daß die Arbeitskammern im Querschnitt kreissektorförmig ausgebildet sind und daß die die Arbeitskammern begrenzenden Flächen der Trennwände in die Mittelachse der Rotationskolben-Brennkraftmaschine schneidenden Axialebenen liegen.This object is achieved in that each piston in cross section Is designed double-T-shaped that the working chambers in cross-section in the shape of a sector of a circle are formed and that the working chambers delimiting surfaces of the partition walls Axial planes intersecting the central axis of the rotary piston internal combustion engine lie.

Im folgenden ist an Hand der Zeichnung ein Ausführungsbeispiel für eine Rotationskolben-Brennkraftmaschine gemäß der Erfindung beschrieben. Die Zeichnung zeigt die Maschine im Querschnitt.In the following, an exemplary embodiment for described a rotary piston internal combustion engine according to the invention. The drawing shows the machine in cross section.

Innerhalb des Mantels 1 ist um dessen Mittelachse 10 die Nabe 2 drehbar gelagert, in der zwei Ausnehmungen 11,12 vorgesehen sind. In den Ausnehmungen 11,12 sind die doppel-T-förmigen Kolben 3, 4 gleichfalls drehbar angeordnet, deren Durchmesser gerade halb so groß ist, wie der Innendurchmesser des Mantels 1. Der von dem Mantel 1 umschlossene Innenraum ist durch die Trennwände 5, 5' in vier Sektoren geteilt, deren jeder eine Arbeitskammer 9 bildet. Die Trennwände 5, 5' schließen den Auslaßkanal 7 ein, wobei die Trennwand 5' in der Mitte etwas kürzer ist als seitlich, so daß ein Durchlaß 13 für die verbrannten Gase entsteht, der die Arbeitskammer 9 mit dem Auslaßkanal verbindet. Die Flächen der die Kammern 9 begrenzenden Trennwände 5, 5' liegen in Achsialebenen, die sich in der Mittelachse 10 der Maschine schneiden. Da sich die Kanten der doppel-T-förmigen Kolben 3, 4 gleichfalls in solchen Ebenen bewegen, ist auf diese Weise eine weitgehende Dichtung der Arbeitskammern 9 bei geringster Reibung gewährleistet, während gleichzeitig die Arbeitskammern eine einfache, nicht zerklüftete Form aufweisen. Auch wird sowohl für den Kompressionsvorgang als auch für die Entspannung der verbrannten Gase eine besonders günstige Angriffsrichtung der auftretenden Kräfte an der Nabe erreicht.Within the shell 1 , the hub 2 is rotatably mounted about its central axis 10, in which two recesses 11, 12 are provided. In the recesses 11, 12 the double-T-shaped pistons 3, 4 are also rotatably arranged, the diameter of which is just half as large as the inner diameter of the jacket 1 'Divided into four sectors, each of which forms a working chamber 9. The partition walls 5, 5 'enclose the outlet channel 7, the partition wall 5' being slightly shorter in the middle than on the side, so that a passage 13 for the burned gases is created which connects the working chamber 9 to the outlet channel. The surfaces of the partition walls 5, 5 ′ delimiting the chambers 9 lie in axial planes which intersect in the central axis 10 of the machine. Since the edges of the double-T-shaped pistons 3, 4 also move in such planes, this ensures extensive sealing of the working chambers 9 with minimal friction, while at the same time the working chambers have a simple, non-jagged shape. A particularly favorable direction of attack of the forces occurring on the hub is also achieved both for the compression process and for the expansion of the burnt gases.

In der Nabe 2 sind die Einlaßkanäle 6 vorgesehen, durch die das explosive Gasgemisch den Arbeitskammern 9 zugeführt werden kann; der öffnungs-und Schließungszeitpunkt für den Gaseintritt werden beispielsweise selbsttätig durch die Nabe 2 gesteuert. Die Bohrungen 8 dienen zum Einsetzen der Zündkerzen. An Stelle eines Gasgemisches kann auch Luft zugeführt werden, die alsdann in den Arbeitskammern 9 komprimiert wird und in die mittels in den Bohrungen 8 an Stelle von Zündkerzen eingesetzter Einspritzdüsen ein beispielsweise flüssiger Brennstoff eingespritzt wird.In the hub 2, the inlet channels 6 are provided through which the explosive Gas mixture can be fed to the working chambers 9; the opening and closing times for the gas inlet are controlled automatically by the hub 2, for example. The holes 8 are used to insert the spark plugs. Instead of a gas mixture Air can also be supplied, which then compresses in the working chambers 9 is and inserted into the means in the bores 8 instead of spark plugs Injection nozzles, for example, a liquid fuel is injected.
