Die Ölschmierung des Kolbens erfolgt durch Kanäle in der Zentralstange und im Kolben.The piston of a four-stroke engine can run two strokes at the same time, the cylinder tube is closed at both ends with a head in which there is a central opening through which a rod slides airtight, which central and vertical the piston, which has two equal circular surfaces penetrates and is firmly connected to it. The piston is lubricated with oil through channels in the central rod and in the piston.

Description

Ein 4-Takt-Motor mit beidseitig befeuertem Kolben geht aus der DE 195 37 055 A1 hervor.A 4-stroke engine with double-fired pistons goes out of the DE 195 37 055 A1 out.

Der Anmeldung liegt die Aufgabe zu Grunde, derartige Motoren zu verbessern.Of the Registration is based on the task of improving such engines.

Schließt man nämlich eine Zylinderröhre an beiden Enden mit je einem Kopf, einer Deckplatte, in der sich je ein Einlaß- und ein Auslaßventil, eine Zünd- oder Glühkerze und eine zentrale Öffnung befinden, durch die eine Stange luftdicht gleitet, die einen Kolben, der zwei gleiche Kreisflächen hat, zentral und senkrecht durchdringt und mit ihm fest verbunden ist, so kann der Kolben bei einer Bewegung zwei Takte ausführen. Die Zentralstange kann sich fortsetzen in einen ebensolchen zweiten Zylinder, wo dann gleichzeitig der dritte und vierte Takt ausgeführt werden. Ein Ende der Zentralstange kann mit einem Pleuel gelenkig verbunden werden und so eine Kurbelwelle treiben. Die kann auch eine zweite Kröpfung haben für den zweiten Zylinder, der dann z.B. neben dem ersten oder ihm leicht schräg gegenüber angeordnet ist. Stellung und Zahl der Zylinder sind wie bisher variabel. Will man keine kreisförmige Bewegung, sondern kann die kurzen geraden Bewegungen der Kolben gebrauchen, so müssen diese Bewegungen in beiden Richtungen z.B. mit Stahlfedern an der Zentralstange begrenzt werden, z.B. dadurch, daß eine Verdickung der Zentralstange eine diese umringende Spiralfeder zusammendrückt. Für die Zündstromverteilung und Ventilsteuerung muß die gerade Bewegung aber dann auch wieder in eine kreisförmige umgewandelt werden.Does one close one namely cylinder tube at both ends, each with a head, a cover plate in which each one intake and an exhaust valve, an ignition or glow plug and a central opening through which a rod slides airtight, which is a piston, the two equal circular areas has penetrated, central and vertical and firmly connected with it is, the piston can perform two cycles during a movement. The Central rod can continue into just such a second Cylinder, where then simultaneously the third and fourth clock are executed. One end of the central rod can be hingedly connected to a connecting rod and so drive a crankshaft. That can also be a second Have cranking for the second cylinder, which is then e.g. next to the first or him easily aslant across from is arranged. Position and number of cylinders are variable as before. Do not want a circular one Movement, but can the short straight movements of the piston need, so must these movements in both directions e.g. with steel springs on the central rod be limited, e.g. in that a thickening of the central rod a compresses this surrounding coil spring. For the ignition current distribution and valve control must the straight movement but then again transformed into a circular become.

Die Ölschmierung der Kolben erfolgt durch einen zentralen Längskanal in der Zentralstange, der in der Mitte des Kolbens unterbrochen ist, wo das Öl durch sternförmig angeordnete Kanälchen in eine breite ringförmige Rinne am Kolbenmantel geführt wird, dort einen Ölgürtel bildet und dann durch einen zweiten Stern von Kanälchen wieder zur Fortsetzung des Zentralkanals gelangt. Auf beiden Seiten des Ölgürtels befinden sich die Dichtungsringe des Kolbens. Die Länge des Kolbens kann reduziert werden, wie die zur Wirksamkeit erforderliche Breite des Ölgürtels und der Dichtungsringe es zulassen.The oil lubrication the piston takes place through a central longitudinal channel in the central rod, which is interrupted in the middle of the piston where the oil passes through star shape arranged canals in a wide annular Channel is guided on the piston skirt, there forms an oil belt and then through a second star of channels again to the continuation of the Central channels arrives. On both sides of the oil belt are the sealing rings of the piston. The length of the piston can be reduced, as required for the effectiveness Width of the oil belt and the sealing rings allow it.

Die Ölschmierung der Zentralstange muß durch eigene Ölbäder erfolgen, wo sie aus dem Zylinder geschoben und nicht vom Kurbelwellenölbad erreicht wird. Alle Ölbäder müssen kommunizieren und das Öl, besonders das vom Kolbengürtel, in Fluß gehalten werden. Vielleicht ist dazu keine eigene Pumpe notwendig, sondern genügen schon zwei Ventile, eines am einen Ende der Zentralstange angebracht, das andere an einer Öffnung des umgebenden Ölbades, und so gebaut und gerichtet, daß sich das eine bei steigendem Druck im Ölbad schließt, während sich das andere öffnet, und sich beide bei fallendem Öldruck, also bei der Gegenbewegung des Kolbens, umgekehrt verhalten. Soll das Öl in die Gegenrichtung fließen, sind die Ventile umzudrehen.The oil lubrication the central rod must go through own oil baths take place, where it is pushed out of the cylinder and not reached by the crankshaft oil bath becomes. All oil baths need to communicate and the oil, especially the piston belt, kept in flow become. Maybe this is not a separate pump necessary, but suffice already two valves, one attached to one end of the central rod, the others at an opening the surrounding oil bath, and so built and judged that the one closes with increasing pressure in the oil bath, while the other opens, and both at falling oil pressure, so in the counter-movement of the piston, behave vice versa. Should the oil flow in the opposite direction, the valves are to be turned over.

Zur Ventilsteuerung an den Zylinderköpfen muß die Nockenwelle je nach Zylinderanordnung in mehrere Stücke geteilt werden, die durch eine geeignete Antriebsmechanik miteinander zu verbinden sind.to Valve control on the cylinder heads must be the camshaft depending on the cylinder arrangement can be divided into several pieces by to connect a suitable drive mechanism with each other.

Der Nachteil dieser größeren Zahl von erforderlichen Teilen und damit von größerem Gewicht, Raumbedarf und vermehrter Reibung schmälert den Gewinn der Teile- und Raumeinsparung im übrigen Motor nur geringfügig.Of the Disadvantage of this larger number of required parts and thus of greater weight, space requirements and Increased friction reduces the gain of parts and space savings in the rest of the engine only slightly.
