Abstract

The invention relates to internal combustion engines; subsumable concept: rotary piston engines. In the rotary piston engine described the cylinders are arranged radially and are accommodated in a rotor. In order to achieve uniform concentric running, 3 pistons or an odd number of pistons are employed. The elongated piston pins engage in guide stars fitted on each side, which are fixed to the housing. The rotor is set in rotation by the downwards movement of the piston. The guide star has 4 tdc and 4 bdc. 2 spark plugs, 2 inlet ports and 2 exhaust ports are located in the housing, see drawing, Fig. 1. The spark plugs are offset by 180@ in relation to one another. The tdc are offset by 90@ in relation to one another. Two working strokes are obtained for one revolution of the working shaft. The engine can be used for all internal combustion engines. <IMAGE>

Description

Die Erfindung betrifft einen Rotationshubkolben­ motor einfachster Bauart. In ihm sind eine ungerade Zahl von Zylindern in einem stationären bzw. sich drehenden Rotor angeordnet.The invention relates to a rotary piston Motor of the simplest design. There are an odd in it Number of cylinders in a stationary or itself rotating rotor arranged.

Es sind derartige Rotationshubkolbenmotoren bekannt DE 34 17 342 C2, P 30 41 405.2, WO 86/05 232 und WO 83/01 649.Such rotary reciprocating piston engines are known DE 34 17 342 C2, P 30 41 405.2, WO 86/05 232 and WO 83/01 649.

Bei den bekannten Motoren wird bei einer Umdrehung nur ein Arbeitshub pro Umdrehung der Arbeitswelle und Kolben erzielt, dementsprechend gering ist auch die Drehmonentabgabe.In the known engines, one revolution only one working stroke per revolution of the working shaft and piston achieved, is accordingly low the torque delivery.

Die Aufgabe der Erfindung besteht darin, den Motor so auszubilden, daß für eine gegebene Anzahl von Kolben-Zylinder-Einheiten eine möglichst große Drehmomentabgabe bei gleichzeitigem schwingungs­ armen- bzw. freien Lauf erzielt wird.The object of the invention is the engine to train so that for a given number of Piston-cylinder units as large as possible Torque output with simultaneous vibration poor or free run is achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Motor folgende Merkmale besitzt:According to the invention, this object is achieved by that the engine has the following features:

  • a) Die beiden Führungssterne sind mit einem jeweils um 90° versetzten OT versehen. Bei der Anordnung von 90° des OT sind die beiden Zündkerzen bei 0° und 180° angebracht.a) The two leadership stars are each with one provided at 90 ° offset OT. When arranging 90 ° of the OT, the two are Spark plugs attached at 0 ° and 180 °.
  • b) Daraus ergibt sich, daß jeder Kolben bei einer 180° Drehung einen Arbeitshub erzielt.b) It follows that each piston at one 180 ° rotation achieved a working stroke.

Bei einer Anordnung von 3 Kolben wird erreicht, daß der Kolben Nr. 1 während seines ersten Arbeits­ hubes den Kolben Nr. 2 aus Verdichten und den Kolben Nr. 3 zum Gasausstoß bringt. Wenn der Kolben Nr. 2 seinen Arbeitshub verrichtet, wird Kolben Nr. 3 verdichten. Daraus ergibt sich ein gleichförmiger Ablauf der einzelnen Arbeitstakte. Mit der Anordnung der 3 Zylinder wird die Wirkung eines 6 Zylinder-Motors erzielt. Die Anordnung der Einlaß- bzw. Auslaßkanäle E + A läßt erkennen, daß es sich um einen Motor handelt, der nach dem Querstromprinzip arbeitet.With an arrangement of 3 pistons it is achieved that the piston No. 1 during its first working stroke brings the piston No. 2 out of compression and the piston No. 3 for gas discharge. When piston # 2 is working, piston # 3 will compress. This results in a uniform sequence of the individual work cycles. With the arrangement of the 3 cylinders, the effect of a 6 cylinder engine is achieved. The arrangement of the inlet and outlet channels E + A shows that it is a motor that works on the cross-flow principle.

Der in Fig. 1, 2, 3 und 4 dargestellte Motor besteht aus einem Gehäuse 1, einem Rotor 2, Kolben 3, zwei Führungssternen 4, mit Gehäusedeckeln 5. Der Rotor ist mit der Arbeitswelle 6 fest verbunden. Die im Gehäuse 1 angebrachten Führungssterne 4 haben jeweils zwei Laufbahnen. Die Laufbahn a ist größer ausgearbeitet als Lauf­ bahn b. Laufbahn a hat die Aufgabe, den Druck der Explosion aufzunehmen, und muß dementsprechend stärker ausgelegt sein als Laufbahn b, die nur dazu dient, ein Abheben von Laufbahn a zu verhindern. So wird ein Kippmoment der Kolben verhindert. Die Arbeitswelle wird mittels zweier Lager in den Gehäusedeckeln 5, gehalten.The motor shown in FIGS. 1, 2, 3 and 4 consists of a housing 1 , a rotor 2 , pistons 3 , two guide stars 4 , with housing covers 5 . The rotor is firmly connected to the working shaft 6 . The guide stars 4 attached in the housing 1 each have two raceways. Career a is more extensive than race b . Career a has the task of absorbing the pressure of the explosion and must accordingly be designed to be stronger than career b , which only serves to prevent career a from being lifted off. This prevents the pistons from tipping over. The working shaft is held in the housing covers 5 by means of two bearings.
