Description

Die Erfindung betrifft eine Rotationskolbenbrennkraftmaschine mit einem Gehäuse, bestehend aus einem Mantel mit mehrbogiger Innenfläche und Seitenteilen, die zusammen einen Innenraum begrenzen, der senkrecht zu den Seitenteilen von einer Exzenterwelle durchsetzt ist, auf deren Exzenter ein mehrbogiger Kolben drehbar gelagert ist, wobei zwischen Kolben, Mantel und Seitenteilen Arbeitskammern gebildet sind, deren Arbeitsablauf durch in axialer Richtung in den Seitenteilen angeordnete Ventile gesteuert wird.The invention relates to a rotary piston internal combustion engine a housing consisting of a jacket with a multi-arched inner surface and side parts, which together define an interior space that is perpendicular to the side panels of one Eccentric shaft is penetrated, on whose eccentric a multi-lobed piston is rotatable is mounted, with working chambers formed between the piston, jacket and side parts are, whose workflow is arranged by in the axial direction in the side panels Valves is controlled.

Bei einer derartigen bekannten Rotationskolbenbrennkraftmaschine sind direkt auf der Exzenterwelle Nocken vorgesehen, die über radial angeordnete Stößelstangen auf Kipphebel einwirken, die jedem Ventil zugeordnet sind. Diese Art der Ventilsteuerung ist nur für Zweitaktbrennkraftmaschinen brauchbar. Für Viertaktbrennkraftmaschinen muß eine gesonderte Nockenwelle vorgesehen sein, da sich bei Viertaktbrennkraftmaschinen diese Nockenwelle mit der halben Geschwindigkeit der Exzenterwelle drehen muß. Es würde sich hierdurch ein verhältnismäßig komplizierter Aufbau der Ventilsteuerung ergeben.In such a known rotary piston internal combustion engine are Cams are provided directly on the eccentric shaft, via radially arranged push rods act on rocker arms associated with each valve. This type of valve control can only be used for two-stroke internal combustion engines. For four-stroke internal combustion engines a separate camshaft must be provided, as in four-stroke internal combustion engines this camshaft must rotate at half the speed of the eccentric shaft. It This would result in a relatively complicated structure of the valve control result.

Der Erfindung liegt die Aufgabe zugrunde, eine Rotationskolbenbrennkraftmaschine der eingangs erwähnten Bauart zu schaffen, bei der die Ventilsteuerung einen besonders einfachen Aufbau aufweist und sowohl für Zweitakt- als auch für Viertaktbetrieb verwendbar ist.The invention is based on the object of a rotary piston internal combustion engine To create the type mentioned at the beginning, in which the valve control is a special has a simple structure and is suitable for both two-stroke and four-stroke operation is usable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einer Rotationskolbenbrennkraftmaschine der eingangs erwähnten Bauart eine Nockenwelle in einer Ebene senkrecht zur Exzenterwelle angeordnet ist, die von der Exzenterwelle angetrieben ist und die Ventile über Kipphebel oder Kipphebel und Stangen direkt betätigt. Durch diese Ausbildung wird die Steuerung für Brennkraftmaschinen nach dem Viertaktprinzip ebenso einfach wie für solche nach dem Zweitaktprinzip. Für Viertaktbetrieb braucht das Getriebe zwischen der Exzenterwelle und der Nockenwelle nur entsprechend ausgelegt zu sein, damit sich bei zwei Umdrehungen der Exzenterwelle die Nockenwelle nur einmal dreht. Gleichzeitig können von der Nockenwelle weitere Hilfsaggregate, wie Ölpumpe, Kraftstoffpumpe und Zündverteiler, angetrieben werden, ohne daß hierdurch die axiale Baulänge des Motors vergrößert wird.According to the invention, this object is achieved in that in a rotary piston internal combustion engine of the type mentioned above, a camshaft in a plane perpendicular to the eccentric shaft is arranged, which is driven by the eccentric shaft and the valves via rocker arms or rocker arms and rods operated directly. This training becomes the control for internal combustion engines based on the four-stroke principle just as easily as for those based on the two-stroke principle. For four-stroke operation, the gear needs to be between the eccentric shaft and the camshaft only needs to be designed accordingly, so that it turns out at two revolutions the eccentric shaft rotates the camshaft only once. At the same time, the Camshaft other auxiliary units, such as oil pump, fuel pump and ignition distributor, be driven without increasing the overall axial length of the motor will.

Ein Ausführungsbeispiel der Erfindung ist im folgenden näher erläutert. Es zeigt F i g.1 einen Längsschnitt durch eine Rotationskolbenbrennkraftmaschine, F i g. 2 einen Querschnitt hierzu.An embodiment of the invention is explained in more detail below. FIG. 1 shows a longitudinal section through a rotary piston internal combustion engine, F i g. 2 shows a cross section for this.

Die in der Zeichnung dargestellte Rotationskolbenbrennkraftmaschine besitzt ein Gehäuse, bestehend aus einem Mantel 3 mit mehrbogiger Innenfläche 4 und Seitenteilen 5, 5', die zusammen einen Innenraum begrenzen. Dieser Innenraum ist senkrecht zu den Seitenteilen 5, 5' von einer Exzenterwelle 8 durchsetzt, auf deren Exzenter 8' ein mehrbogiger Kolben 1 drehbar gelagert ist. Die Außenkontur dieses Kolbens ist mit 2 bezeichnet. Hierbei werden zwischen Kolben, Mantel und Seitenteilen Arbeitskammern gebildet, deren Arbeitsablauf durch in axialer Richtung in dem Seitenteil s angeordnete Ventile 7 gesteuert wird.The rotary piston internal combustion engine shown in the drawing has a housing consisting of a jacket 3 with a multi-arched inner surface 4 and side parts 5, 5 ', which together define an interior space. This interior is perpendicular to the side parts 5, 5 'penetrated by an eccentric shaft 8, on the eccentric 8 'of which a multi-arch piston 1 is rotatably mounted. The outer contour this piston is denoted by 2. Here are between the piston, jacket and Formed side parts working chambers, the work flow through in the axial direction in the side part s arranged valves 7 is controlled.

Erfindungsgemäß ist in einer Ebene 9 senkrecht zu der Exzenterwelle 8 eine Nockenwelle 10 angeordnet, die über das Getriebe 11 von der Exzenterwelle 8 angetrieben wird. Von dieser Nockenwelle 10 werden die Ventile 7 mittels Kipphebeln und Stangen gesteuert. Zur Unterscheidung der einzelnen Ventile sind diese in den Zeichnungen mit den Buchstaben A bis J bezeichnet.According to the invention, in a plane 9 is perpendicular to the eccentric shaft 8 a camshaft 10 is arranged, which via the gear 11 of the eccentric shaft 8 is driven. From this camshaft 10, the valves 7 by means of rocker arms and rods controlled. To distinguish between the individual valves, these are shown in the Drawings designated with the letters A to J.

Wie weiterhin aus der Zeichnung ersichtlich ist, können an der Nockenwelle der Zündverteiler 17 sowie die Ölpumpe 18 angeordnet sein. Mittels eines weiteren Nockens 15 wird die Kraftstoffpumpe 16 betätigt. Es wird also nur ein einziges Zahnradpaar für den Antrieb der Nockenwelle 10, des Zündverteilers 17, der Ölpumpe 18 und der Kraftstoffpumpe 16 benötigt.As can also be seen from the drawing, on the camshaft the distributor 17 and the oil pump 18 can be arranged. By means of another Cam 15, the fuel pump 16 is actuated. So there will only be a single pair of gears for driving the camshaft 10, the distributor 17, the oil pump 18 and the Fuel pump 16 required.
