Bei Verbrennungsmotoren, bei welchen die Zylinder entgegengesetzt der Richtung der Kurbelwelle sich drehen, wurde versucht, die gyroskopischen Kräfte durch Gegengewichte an der Kurbel auszugleichen. Beim Gegenstand der Erfindung sind jedoch die Zylinder gruppenweise angeordnet, wobei die Kolben um eine feststehende Achse rotieren. Jede Gruppe bildet eine Maschine für sich und dreht sich entgegengesetzt der Richtung der andern Gruppe, so daß die gyroskopischen Wirkungen nicht durch ein totes Gewicht, sondern durch eine Arbeit leistende Maschine ausgeglichen werden. Die beiden Gruppen drehen sich vorzugsweise umIn internal combustion engines, in which the cylinders are opposite to the direction of the Crankshaft turning, an attempt was made to counterbalance the gyroscopic forces balance the crank. In the subject matter of the invention, however, the cylinders are in groups arranged, wherein the pistons rotate about a fixed axis. Each group educates a machine of its own and turns opposite to the direction of the other group, so that the gyroscopic effects are not caused by a dead weight, but by work performing machine can be compensated. The two groups preferably turn around

Fig. ι ist eine Draufsicht auf ein Ausführungsbeispiel einer solchen Maschine und Fig. 2 ein Schnitt durch einen Zylinder und das Getriebe. Der in der Zeichnung dargestellte Motor besteht aus zwei Zylindergmppen ι und 2, welche so gelageit sind, daß sie in entgegengesetzten Richtungen um die gleiche feststehende Achse rotieren. Jede Gruppe besteht aus einer Anzahl von Zylindern 3, die sternförmig um die feststehende Achse herum angeordnet sind. Aus Fig. 2 ist die innere Konstruktion jeder Gruppe ersichtlich. Zwischen jedem Paar anstoßender Zylinder stehen Befestigungsflanschen 6 vor, mit deren Hilfe die Zylinder vermittels der Schrauben 7 aneinander befestigt werden. Über die Schultern 4 und Flanschen 5 der Zylinder greift ein Paar gegenüber angeordneter Deckelplatten oder Kappen 8, welche ein luft- und gasdichtes Kurbelgehäuse bilden. In jedem Zylinder 3 ist hin und her bewegbar ein hohler Kolben gelagert, welcher vermittels einer Pleuelstange 11 mit einem festliegenden Kurbelzapfen 56 verbunden ist. Da die Zylinder 3 um eine feste Achse rotieren, während die Kolben 9 um den im Abstand von der festen Achse angeordneten Kurbelzapfen rotieren, so werden während der Drehung der Zylinder die Kolben 9 mit Bezug auf die Zylinder 3 nach innen und außen bewegt.Fig. Ι is a plan view of an embodiment of such a machine and FIG Section through a cylinder and the gearbox. The engine shown in the drawing consists of two cylinder groups ι and 2, which are guided so that they are in opposite directions Rotate directions around the same fixed axis. Each group consists of one Number of cylinders 3, which are arranged in a star shape around the fixed axis. From Fig. 2, the internal construction of each group can be seen. Adjacent between each pair Cylinders are facing mounting flanges 6, with the help of which the cylinder mediates the screws 7 are fastened to one another. Over the shoulders 4 and flanges 5 the cylinder engages a pair of oppositely disposed cover plates or caps 8, which form an airtight and gas-tight crankcase. In each cylinder 3 can be moved back and forth a hollow piston mounted, which by means of a connecting rod 11 with a fixed Crank pin 56 is connected. Since the cylinders 3 rotate around a fixed axis, while the pistons 9 rotate around the crank pin arranged at a distance from the fixed axis, so During the rotation of the cylinders, the pistons 9 move with respect to the cylinders 3 moved inside and out.

In Fig. ι ist eine Fußplatte 44 dargestellt, auf welcher ortsfest ein Paar Lagerböcke 45 und 46 gelagert sind, welche mit konachsialen Lagern in ihren äußeren Enden versehen sind. In dem Lager in dem äußeren Ende des Lagerbockes 46 ist eine Welle 47 vermittels eines Stiftes 48 befestigt, der sowohl durch das Lager als auch die Welle hindurchgeht. Die Gruppe oder Hälfte 2 des Motors ist auf dieser Welle 47 und auf der von dem oberen Ende 50 des mittleren Lagerbockes 51 vorstehenden Zapfen welle 49 drehbar gelagert. Der Zapf en welle 49 gegenüber ist eine zweite Zapfenwelle 52 gelagert, auf welcher drehbar die Zylindergruppe 1 gelagert ist. Auf dem Ende dieser Welle 52 ist vermittels eines Stiftes 54 ein Kurbelarm 55 befestigt, welcher mit einem mit ihm einheitlich ausgebildeten und seitlich vorstehenden Kurbelzapfen 56 versehen ist; der letztere trägt an seinem Ende eine Schraube 57, vermittelst deren er an einem zweiten Kurbelarm 58 befestigt ist, welcher an einer Hülse 59 sitzt, die durchIn Fig. Ι a base plate 44 is shown on which stationary a pair of bearing blocks 45 and 46 are mounted, which with conaxial bearings are provided in their outer ends. In the bearing in the outer end of the bearing block 46 a shaft 47 is secured by means of a pin 48 which passes through both the bearing and the Wave passes through it. The group or half 2 of the engine is on this shaft 47 and on the pin shaft 49 protruding from the upper end 50 of the central bearing block 51 rotatably mounted. A second pin shaft 52 is mounted opposite the pin shaft 49, on which the cylinder group 1 is rotatably mounted. On the end of this shaft 52 is by means of a pin 54, a crank arm 55 is attached, which is integral with one with it formed and laterally projecting crank pin 56 is provided; the latter carries on at its end a screw 57, by means of which it is attached to a second crank arm 58 is, which sits on a sleeve 59 that passes through

Claims

the pin 6ο ^Λ is attached to the shaft 53. As can be seen from FIG. 2, a metal chuck 60 * is provided between the pin shaft 53 xind of a coil-like sleeve 61; the sleeve 61 is provided with a connecting flange 62 abutting the crankcase, by means of which it is fastened to the cover plate 8, and furthermore has a flange 63 at its outer end for connection to the coupling member 64 of a drive shaft 65 carries a bearing shell 66 in which the sleeve 61 is mounted.

As can be seen from Fig. 1 and 2, the opposite cover plates 8 are the Cylinder groups in rigid connection with bevel gears 79 and 80, which with a Pair of bevel gears 81 mesh so that the two cylinder groups are mechanically connected stand. The bevel gears 81 are mounted on pins 82 which are laterally of the the outer end of the central bearing block 51 protrude. As can be seen from Fig. 2, each of the peg shafts 49, 52 designed to be hollow to provide a passage for the fuel-air mixture to create inside the crankcase. For that purpose is the top end of the middle bearing block 51 is provided with an inlet channel 83, which is in two after Branch channels 84 and 85 leading to the hollow interiors of the PTO shafts 49 and 52 forks. Within the hollow interior of the bearing block 51 is connected to the inlet channel 83 Feed line 86 stored. The channels 84 and 85 are equipped with three-way valves 87 and 88. This facility allows to turn the three-way cock 87 or 88 in such a position that only the motor half 1 or only the motor half 2 is supplied with carburized air while the carburized air is admitted Air to the motor half 2 or to the motor half ι through the three-way valve 88 or 87 is cut off. Here, the three-way cock in question is set so that it not only closes the access of carburized air to the half of the engine controlled by it, but also the interior of the housing with a channel 80 leading to the outside atmosphere in Connection.

With the three-way cock in this position, pure air is drawn into the crankcase and into the Cylinder through the pistons .pumped so that the individual parts of this engine half are thoroughly be cooled. At the same time, this engine half fulfills due to its mechanical connection with the other half of the motor by means of the bevel gears 79, 80 and 81 the function a flywheel for the engine half in operation and overwinds at the same time the gyroscopic effects of them. Since the valve control on the inner wall of the Cover plate 8, directly opposite and in line with the outlet of the gas-air mixture is mounted in the crankcase, so when a lubricant is introduced with the gas-air mixture, the various Parts of the control system thoroughly and continuously lubricated; this is the case with an engine of this type a property of great importance. In addition, the control parts are those responsible for the lubrication most need to be located some distance from the axis of rotation, so that the lubricant by centrifugal force is thrown at these parts. Accessible to the inside of the crankcase To make it is only necessary to remove one of the outer cover plates 8, which carries a large part of the control.
