Beschreibung description
liv erbrennungskrf tmnschine" Die Erfindung bezieht sich auf eine Verbrennungskraftmaschine, bestehend aus einem Gehäuse, einem Rotor in dem Gehäuse mit radial verlaufenden Zylinderbohrungen, Kolben in den Bohrungen, einer weitgehend ovalen Führung für eine zweimalige Hin- und Herbewegung der Kolben pro einer Rotorumdrehung, welche Führung aus einer ersten nach außen weisenden Fläche und einer zweiten nach innen weisenden Fläche besteht, einer Zündkerze und An-und Absaugkanälen im Gehäuse. liv ernigungskrf tmnschine "The invention relates to a Internal combustion engine, consisting of a housing, a rotor in the housing with radial cylinder bores, pistons in the bores, one largely oval guide for two reciprocating movements of the pistons per revolution of the rotor, which guide consists of a first outward-facing surface and a second after inside facing surface consists of a spark plug and intake and exhaust channels in the housing.
Bei einer bekannten Maschine dieser Art (DE-OS 26 48 395) befinden sich zwei erste und zweite Führungsflächen jeweils seitlich neben den Kolben. Auf diesen rollen zwei Rollen, die über eine einen Kolben durchdringende und mit diesem fest verbundene Welle miteinander verbunden sind. Diese Konstruktion hat den Nachteil, daß sich die Welle verbiegen kann. Hinzu kommt, daß die Herstellung der Maschine insofern erhebliche Schwierigkeiten bereitet, als die beiden Führungsflächen absolut gleich geartet sein sollten, was in der Praxis nur annäherungsweise erreicht werden kann. Schließlich sind die beiden Führungsflächen Kühlräumen, die möglichst nahe an die Zylinderräume herangelegt werden müssen, im Wege.In a known machine of this type (DE-OS 26 48 395) are located there are two first and second guide surfaces on each side of the piston. on These roll two roles, one of which penetrates a piston and with it firmly connected shaft are connected to each other. This construction has the disadvantage that the shaft can bend. In addition, the manufacture of the machine to the extent that it causes considerable difficulties, as the two guide surfaces absolutely should be of the same type, which in practice can only be approximated can. After all, the two guide surfaces are as close as possible to cooling spaces to the cylinder spaces must be placed in the way.
Der Erfindung liegt die Aufgabe zugrunde, die eingangs erwähnte Verbrennungskraftmaschine derart auszubilden, daß sie einfacher und genauer als die bekannte Maschine herstellbar ist und daß ein einwandfreier Betrieb mehr als bei dieser gewährleistet ist.The invention is based on the object of the internal combustion engine mentioned at the outset to be designed in such a way that they can be produced more easily and precisely than the known machine is and that perfect operation is guaranteed more than with this one.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kolben die erste und/oder zweite Führungsfläche übergreifen.This object is achieved according to the invention in that the pistons overlap the first and / or second guide surface.
Auf diese Weise wird folgendes erreicht: Einerseits entfällt die bei der bekannten Maschine vorgesehene Welle, die sich während des Betriebes verbiegen kann. Andererseits ist nur eine erste und/oder zweite Führungsfläche vorhanden, so daß das Problem entfällt oder reduziert ist, zwei Kurven so zu bearbeiten, daß sie möglichst gleich ausgebildet sind. Schließlich kann bei der erfindungsgemäßen Maschine der Kühlraum dichter an die Zylinderräume herangebracht werden.In this way, the following is achieved: On the one hand, the is omitted of the known machine provided shaft, which is during of Operation can bend. On the other hand, there is only a first and / or second guide surface present, so that the problem is eliminated or reduced to process two curves in such a way that that they are designed as identically as possible. Finally, in the case of the invention Machine the cold room can be brought closer to the cylinder rooms.
Eine Weiterentwicklung der Erfindung besteht darin, daß die Führung eine solche, von der ovalen Form abweichende Form hat, daß die Kolben im Hinblick auf den Wirkungsgrad optimale Bewegungen vollführen.A further development of the invention is that the leadership has such a shape deviating from the oval shape that the piston with respect to perform optimal movements for efficiency.
So ist es in Weiterbildung dieses Gedankens insbesondere sinnvoll, daß der Arbeitshub der Kolben kleiner als der Gas-Ausstoß-Hub ist und/oder daß der Gas-Ansaughub der größte Hub von allen Hüben ist.In further developing this idea, it is particularly useful to that the working stroke of the piston is smaller than the gas ejection stroke and / or that the Gas suction stroke is the largest stroke of all strokes.
Weiterhin wird vorgeschlagen, daß die Abtriebswelle der Maschine nur auf einer Seite aus dem Gehäuse herausragt und daß die die Führungsflächen aufweisenden Teile auf der anderen Seite des Gehäuses an diesem befestigt sind. Der Vorteil dieser Maßnahme besteht' darin, daß die Kolben bzw. die Zylinder relativ weit bis zum Zentrum des Gehäuses heranreichen können, so daß die Kolben entsprechend lang sein können und damit eine gute Führung besitzen.It is also proposed that the output shaft of the machine only protrudes from the housing on one side and that the guide surfaces having Parts on the other side of the housing are attached to this. The advantage of this Measure is' that the piston or the cylinder relatively far to the center of the housing can reach so that the pistons can be correspondingly long and thus have good leadership.
Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung. Darin zeigen: Fig. 1 einen Querschnitt durch eine Verbrennungskraftmaschine gemäß der Erfindung nach der Linie I-I der Fig. 2, Fig. 2 einen Schnitt nach der Linie 11-11 der Fig. 1, Fig. 3 einen Schnitt nach der Linie III-III der Fig. 2 und Fig. 4 eine Einzelheit.Further details of the invention emerge from the drawing. 1 shows a cross section through an internal combustion engine according to FIG of the invention along the line I-I of FIG. 2, FIG. 2 shows a section along the line 11-11 of Fig. 1, Fig. 3 is a section along the line III-III of Figures 2 and 4 show a detail.
Der in den Fig. 1 - 3 veranschaulichte Motor besteht aus einem Gehäuse 1, einem Rotor 2, Kolben 3, die in radialer Richtung in Zylindern 4 des Rotors 2 hin- und herlaufen, einer Platte 5, die eine erste Führungsfläche 6 besitzt,und einer zweiten Platte 7, die eine Führungsfläche 8 aufweist. Die Kolben berühren die Führungsfläche 6 mit einer Spitze 9 und die Führungsfläche 8 mit einer Rolle 10. Mit 11 ist eine Zündkerze, mit 12 ein Gas-Auslaßkanal und mit 13 ein Gas-Ansaugkanal bezeichnet. Eine Abtriebswelle 14 ist an dem Rotor 2 festgeschraubt und mittels Lager 15 im Gehäuse 1 gelagert. Ferner ist an dem Rotor 2 ein Rohr 16 befestigt, das mittels eines Lagers 17 in dem Gehäuse gelagert ist und durch das öl in einen ersten Kühlraum 18 strömt, von wo das öl in Hohlräume 19 und durch Kanäle 20 (s. Fig. 1) in die Zylinderräume strömt. Das Gehäuse 1 besteht aus einer Gehäuseschale 1a und einem Gehäusedeckel 7b, der an der Gehäuseschale 1a festgeschraubt ist und über weitere Schrauben die Platten 5 und 7 trägt. Mit 20 sind Dichtungsringe bezeichnet, die die Zylinderräume umgeben und diese gegenüber dem Gehäuse abdichten. Der Rotor 2 ist mit Rollen 21 bestückt, die auf der Platte 7 laufen.The engine illustrated in Figures 1-3 consists of a housing 1, a rotor 2, pistons 3, which in the radial direction in cylinders 4 of the rotor 2 back and forth, a plate 5 which has a first guide surface 6, and a second plate 7 which has a guide surface 8. Touch the pistons the guide surface 6 with a tip 9 and the guide surface 8 with a roller 10. With 11 is a spark plug, with 12 a gas outlet channel and with 13 a gas intake channel designated. An output shaft 14 is screwed to the rotor 2 and means Bearing 15 mounted in the housing 1. Furthermore, a tube 16 is attached to the rotor 2, which is mounted by means of a bearing 17 in the housing and through the oil in a first cooling chamber 18 flows, from where the oil flows into cavities 19 and through channels 20 (see Fig. Fig. 1) flows into the cylinder spaces. The housing 1 consists of a housing shell 1a and a housing cover 7b, which is screwed to the housing shell 1a and The plates 5 and 7 are supported by further screws. With 20 sealing rings are designated, which surround the cylinder spaces and seal them against the housing. The rotor 2 is equipped with rollers 21 which run on the plate 7.
Während des Betriebes dreht sich der Rotor 2 in dem Gehäuse 1, und zwar in bezug auf Fig. 1 im Uhrzeigersinn. Die Kolben 3 vollführen während einer Umdrehung des Rotors 2 eine zweimalige Hin- und Herbewegung, d.h. es folgen in üblicher Art und Weise aufeinander: der Arbeitshub, bei dem das Luft-Gas-Gemisch, welches von der Zündkerze 11 gezündet worden ist, den Kolben nach innen drückt, was zur Folge hat, daß dem Rotor eine Drehbewegung oktroyiert wird; der Gas-Ausstoß-Hub, bei dem die verbrannten Gase aus dem Gas-Austrittskanal 12 austreten; der Gas-Ansaughub, bei dem ein Luft-Gas-Gemisch über den Kanal 13 in den Zylinder angesaugt wird; der Verdichtungshub, bei dem das in dem Zylinder befindliche Gas verdichtet wird. Das Verdichtungsverhältnis ist bei dem erfindungsgemäßen Motor das gleiche wie bei einem Kolbenmotor.During operation, the rotor 2 rotates in the housing 1, and with respect to FIG. 1 in a clockwise direction. The piston 3 perform during a Rotation of the rotor 2 a double back and forth movement, i.e. it follows in the usual way Way on each other: the working stroke, in which the air-gas mixture, which has been ignited by the spark plug 11, pushes the piston inwards, which leads to The consequence is that a rotary movement is imposed on the rotor; the gas exhaust stroke, in which the burned gases emerge from the gas outlet duct 12; the gas intake stroke, at an air-gas mixture is sucked into the cylinder via the channel 13; the compression stroke, in which the gas in the cylinder is compressed. The compression ratio is the same in the engine according to the invention as in a piston engine.
Eine wesentliche Weiterentwicklung der Erfindung ist in der Form der beiden Führungskurven 8 und 9 zu erblicken. Diese sind, wie der Fig. 1 zu entnehmen ist, nicht rein oval, sondern so geartet, daß die Kolben Hübe vollführen, die besonders günstig sind. So sind die Kurven derart ausgebildet, daß der Gas-Ansaughub der größte aller Hübe ist und der Arbeitshub kleiner als der Gas-Ausstoß-Hub ist.A major advancement of the invention is in the form of the can be seen on both guide curves 8 and 9. These can be seen from FIG. 1 is not purely oval, but designed in such a way that the pistons perform strokes that are special are cheap. The curves are designed in such a way that the gas intake stroke is the largest of all strokes and the working stroke is smaller than the gas ejection stroke.
Die Räume in den Fig. 1 - 3, die mit horizontalen Strichen ausgefüllt sind, sind mit Wasser gefüllte Kühlräume.The spaces in Figs. 1-3, filled in with horizontal lines are cold rooms filled with water.
Fig. 4 zeigt eine Abwandlung gegenüber der Ausführungsform gemäß den Fig. 1 - 3. Diese Figur zeigt einen Kolben 3 innerhalb eines Zylinders 4. Die zweite Führungsfläche befindet sich in diesem Falle ebenfalls in einem solchen Bereich, daß sie von dem Kolben umgriffen wird. Sie ist mit 8' bezeichnet.Fig. 4 shows a modification compared to the embodiment according to the Figs. 1-3. This figure shows a piston 3 within a cylinder 4. The second In this case, the guide surface is also located in such an area that it is encompassed by the piston. It is labeled 8 '.
Anspruch 6 hat auch unabhängig vom Kennzeichen des Anspruchs 1 Bedeutung.Claim 6 also has meaning regardless of the characteristic of claim 1.
