Description

Schiebersteuerung für Viertaktbrennkraftmaschinen mit gegenläufigen Kolben Es sind Schiebersteuerungen für Viertaktbrennkraftmaschinen mit gegenläufigen Kolben bekannt, welche mit einem einzigen Rohrschieber arbeiten. Hierbei liegen aber die Sehlitze des Rohrschiebers auf verschiedenen Höhen, wodurch nicht verhindert werden kann, daß Schlitze von den Kolbenringen eines Arbeitskolbens bestrichen werden können, was ein Hängenbleiben möglich macht. Um diesen Nachteil zu verhindern, ist beim Gegensand der vorliegenden Erfindung der Rohrschieber mit in einer Reihe in gleicher Höhe liegenden Schlitzen versehen, welche abwechselnd den Einlaß und den Auspuff steuern. Dabei bewegt sich die Schlitzreihe nur zwischen den Bahnen der Kolbenringe der beiden Arbeitskolben und legt in ihrer Mittelstellung die Zündkerzen frei.Slide control for four-stroke internal combustion engines with counter-rotating Pistons There are slide controls for four-stroke internal combustion engines with counter-rotating Pistons known which work with a single pipe slide. Here lie but the seatballs of the tubular valve at different heights, which does not prevent can be that slots are swept by the piston rings of a working piston can do what makes getting stuck possible. To prevent this disadvantage is In the subject of the present invention, the pipe slide with in a row in the same height provided slots, which alternate the inlet and the Control the exhaust. The row of slots only moves between the tracks of the Piston rings of the two working pistons and places the spark plugs in their middle position free.

In der Zeichnung ist der Gegenstand der Erfindung in-einem Ausführungsbeispiel dargestellt und zeigt Fig. i die Maschine in senkrechtem Schnitt, Fig.2 die Stellung des Schiebers während des Einlasses, Fig.3 denselben während der Explosion und -Fig. q. denselben in der Auspuffstellung. Es sind i und 2 zwei gleichachsig übereinanderliegende und starr miteinander verbundene Zylinder, in welchen sich die mit Dichtungsringen 5 versehenen Kolben 3 und q. durch Getriebe 6 gegenläufig bewegen. Es ist 7 (Fig.3) der Explosionsraum, welcher den beiden Zylindern i und 2 gemeinsam ist. Zwischen den Wänden der Zylinder i und 2 und den Kolben 3 und q. befindet sich ein dünner, zylindrischer Rohrschieber 8, welcher durch ein Getriebe i o an sich bekannter Art eine ungleichmäßig oszillierende Bewegung erhält. Es ist i i der Einlaß und 12 der Auspuff. 13 und 1¢ sind die Zündkerzen. Der Rohrschieber 8 hat in seiner Mitte eine einzige Reihe von Schlitzen 15, mit deren Hilfe die Steuerung von Einlaß i i und Auspuff i z erfolgt. Dabei liegen die zur Zylinderachse quer gerichteten Kanten 17 der Schlitze 15 außerhalb der von den Kolben 3 und q. bestrichenen inneren Zylinderfläche (Fig. z bis q), so daß ein Hängenbleiben der Kolbenringe 5 an den Schlitzen i 5 nicht stattfinden kann. Damit die Dichtung des Schiebers bei der Verdichtung durch den Innendruck erfolgt, sind in den Kanten 17 der Schlitze 15 Einschnitte 16. Weil die Kolben 3 und q. in einander entgegengesetzten Richtungen laufen, so werden sämtliche seitlichen Kolbendrücke auf den Schieber 8 aufgehoben.In the drawing, the subject matter of the invention is in an exemplary embodiment and shows Fig. i the machine in vertical section, Fig.2 the position of the slide during the inlet, Fig. 3 the same during the explosion and -Fig. q. same in the exhaust position. There are i and 2 two coaxially superimposed and rigidly interconnected cylinders, in which the with sealing rings 5 provided piston 3 and q. move in opposite directions through gear 6. It's 7 (Fig.3) the explosion space, which is common to the two cylinders i and 2. Between the walls of cylinders i and 2 and pistons 3 and q. there is a thin, cylindrical pipe slide 8, which by a gear i o known type receives an unevenly oscillating movement. It's i i the inlet and 12 the Exhaust. 13 and 1 ¢ are the spark plugs. The pipe slide 8 has one in its center single row of slots 15 by means of which the control of inlet i i and Exhaust i z takes place. The edges directed transversely to the cylinder axis are located here 17 of the slots 15 outside of the piston 3 and q. painted inner cylinder surface (Fig. Z to q), so that the piston rings 5 sticking to the slots i 5 cannot take place. So that the seal of the slide through the compression the internal pressure takes place, in the edges 17 of the slots 15 incisions 16. Because the pistons 3 and q. run in opposite directions, so will all Lateral piston pressures on the slide 8 canceled.

Außerdem hat der Gegenstand der Erfindung den- Vorteil, daß die Durchgänge, weil nur eine einzige Schlitzreihe vorhanden ist, große Querschnitte erhalten können, zumal da jede der beiden Kanten 17 die eine den Auspuff und .die andere den Einlaß steuert.In addition, the object of the invention has the advantage that the passages, because there is only a single row of slots, large cross-sections can be obtained, especially since each of the two edges 17 the one the exhaust and .the other the inlet controls.
