Abstract

The rotary-cylinder engine is of the internal-combustion four-stroke type. The pistons (3) are mounted symmetrically and radially in cylinders (2) in a disc. The pistons bear via bosses and rollers against a central cam (1), so that as the disc containing the cylinders rotates they describe an oval path, thus moving up and down in the cylinders. There can be inlet and outlet ports in the housing (4), so that no valves are needed, while a single sparking plug in the housing can be arranged to serve all pistons.

Römerstr. 16 7590 Achern 18 Beschreibung Titel: Rotationszylindermotor Der Rotationszylindermotor ist ein Viertakt-Verbrennungsmotor. Die Kolben (3) befinden sich mit den Zylindern (Zylinderscheibe (2)) drehbar in einem kreisförmigen Gehäuse. Über Zapfen und Nadellager sind die Kolben mit einem Nocken in der Mitte des Gehäuses (Zentralnocken (1)) verbunden, um den sie eine ovale Bahn beschreiben. Der Zentralnocken (1) ist fest mit dem äu3eren Gehäuse (4) verbunden.Römerstrasse 16 7590 Achern 18 Description Title: Rotary cylinder engine The rotary cylinder engine is a four-stroke internal combustion engine. The pistons (3) are located rotates with the cylinders (cylinder disk (2)) in a circular housing. The pistons with a cam are located in the center of the housing via journals and needle bearings (Central cam (1)) around which they describe an oval path. The central cam (1) is firmly connected to the outer housing (4).

Beim Drehen der Zylinderscheibe (2) um den Zentralnocken (1) bewegen sich die Kolben (3) auf Grund der ovalen Gestalt des Zentralnocken <1) pro Umdrehung zweimal auf und ab Dabei wird über eine Öffnung im äußeren Gehäuse angesaugtes Gemisch verdichtet, gezündet, verbrannt und über eine weitere Öffnung wieder ausgestoßen. Steuerungsventile sind nicht erforderlich. Auf jede Umdrehung der Zylinderscheibe (2) kommen vier Arbeitstakte. Da Zündung und Verbrennung immer an der gleichen Stelle erfolgen, ist nur eine Zündkerze erforderlich.When turning the cylinder disk (2) move around the central cam (1) the pistons (3) move <1) per revolution due to the oval shape of the central cam twice up and down The mixture is sucked in through an opening in the outer housing compressed, ignited, burned and ejected again through another opening. Control valves are not required. On every revolution of the cylinder disk (2) there are four work cycles. Since ignition and combustion are always in the same place only one spark plug is required.

In der Zylinderscheibe (2) befindet sich ein Zahnkranz über den die Antriebswelle (5) angetrieben wird.In the cylinder disk (2) there is a ring gear over which the Drive shaft (5) is driven.

Vorteile des Rotationszylindermotors gegenüber dem Viertakt-Ottomotor 1. Durch die kreisförmige Bewegung der Zylinderscheibe ist ein vibriationsarmer Lauf zu erwarten.Advantages of the rotary cylinder engine compared to the four-stroke gasoline engine 1. Due to the circular movement of the cylinder disk there is less vibration Run to be expected.

2. Der Motor kann sehr klein und kompakt gebaut werden. 2. The motor can be built very small and compact.

3 Der Motor besitzt keine Ventile und damit auch keine Steuerungselemente für Ventile mit hin und ker bewegenden Massen. 3 The motor has no valves and therefore no control elements for valves with reciprocating masses.

4. Es ist nur eine Zündkerze erforderlich 5. Technologische Erkenntnisse des Otto-otors hinsichtlich 3rennraumgestaltun-g, Z-ündzetpunkt, Verdichtung usw können weitgehend übernommen werden 6 Der Bewegungsablauf der Kolben insbesondere nahe des oberen und unteren Totr--urJrt-es kann durch die Foragebung des Zentralnockens weitgehend beeinflußt werden. Dabei kann der Bewegungsablauf der Kolben für die vier Takte Ansaugen, Verdichten, Verbrennen und Ausstoßen unterschiedlich gestaltet werden 'ilfried tarck Kfz.-Meister Reiersbacher Str. 30 7592 Renchen-Ulm Reinhold Stark Dgl.Hdl. 4. Only one spark plug is required. 5. Technological knowledge of the gasoline engine with regard to the design of the racing space, ignition point, compression, etc. can largely be adopted 6 The sequence of movements of the pistons in particular near the upper and lower Totr - urJrt - it can be due to the shaping of the central cam are largely influenced.

Römerstr. 16 7590 Achern 18 Vorteile des Rotationszylindermotors gegenüber dem Zweitaktmotor Trotz einfacher Schlitzsteuerung ergibt sich ein sauberer Gaswechsel vorteile des Hotationszylindermotors gegenüber dem Siankelmotor Abdichtungsprobleme sind wesentlich einfacher zu lösen, da die Zvlinderscheibe in einem kreisförmigen Gehause rotiert. Mit Rattermarken ist deshalb nicht zu rechnen.Römerstrasse 16 7590 Achern 18 Advantages compared to the rotary cylinder engine the two-stroke engine Despite the simple slot control, the gas exchange is clean advantages of the hotation cylinder motor compared to the siankelmotor sealing problems are much easier to solve because the cylinder washer is in a circular shape Housing rotates. Chatter marks are therefore not to be expected.

Die Beschreibung eines lRotationszylindermotors im Schrifttum ist uns nicht bekannt ;ir sind uns bewußt, daß zur Ilerstellung eines funktionsfnhigen Modells und erst recht für einen Serienmotor noch eine Menge technischer Probleme zu lösen sind. Die Dimensionierung aller Teile ist zu rufen. Dt Formgebung des Zentralnockens hat einen eltscheidenden Einfluß auf den ;girkunsgrad und dürfte nur empirisch zu finden sein.The description of a rotary cylinder engine in literature is not known to us; we are aware that to create a functional Model and even more so for a series engine there are still a lot of technical problems are to be solved. The dimensioning of all parts is to be called. Dt shape of the central cam has a decisive influence on the degree of efficiency and should only be empirical find his.

Gehäuse und Zentralnocken wird man am besten aus mehreren Teilen herstellen, die dann versc@@@@@ werden.Housing and central cams are best made from several parts, which then become versc @@@@@.

Da die Verbrennungskräfte durch die iorm des Zentralnockens in eine Rotationsbewegung des Zylinderscheibe umgesetzt werden, treten zwisc,len Kolben und Zylinderwand erhebliche Drücke auf, die u.U. durch ein RuFel- oder Nadellager aufzefangen werden müssen. Weitere Überlezungen müssen angestellt werden hinsichtlich des Materials der Teile, Kühlung von Gehäuse und Zylinder usw.Since the combustion forces through the iorm of the central cam in a Rotational movement of the cylinder disk are implemented, occur between pistons and cylinder wall on considerable pressures, which may be caused by a roller or needle bearing must be collected. Further reflections must be made regarding the material of the parts, cooling of the housing and cylinder, etc.
