Description

Doppeltwirkende Zweitaktbrennkraftmaschine Die Erfindung betrifft eine doppeltwirkende Zweitaktbrennkraftmaschine mit einem auf der Arbeitskolbenstange sitzenden, als Kolben einer doppeltwirkenden Ladepumpe dienenden Kreuzkopf, dessen mit dem Arbeitskolben gemeinsame Kolbenstange in einer den einwärts liegenden Arbeitsraum gegen den auswärts liegenden Pumpenraum trennenden Wand geführt ist. Bei einer solchen Maschine ist für eine gute Abdichtung der in der Trennwand gleitenden Kolbenstange zu sorgen. Zu diesem Zweck ist erfindungsgemäß folgende Einrichtung vorgesehen. In einer in der Zwischenwand vorgesehenen Ringkammer liegen zwei Dichtungsringe ,mit einem Querschnitt von der Form eines rechtwinkligen Dreiecks nebeneinander an der Kolbenstange und werden von zwei Ringen ebensolchen Querschnitts, die mit ihren Hypotenusen an denjenigen der erstgenannten Ringe und mit der einen Kathete an der Ringwand der Kammer liegen, an die Kolbenstange angedrückt, und zwar durch den Druck in dem an die Trennwand sich anschließenden Arbeitsraum einerseits und denjenigen. in dem an die Trennwand sich anschließenden Pumpenraum anderseits, welche Drücke sich durch feine Bohrungen in den beiden Stirnwänden der Kammern auf letztere fortpflanzen.Double Acting Two-Stroke Internal Combustion Engine The invention relates to a double-acting two-stroke internal combustion engine with one on the working piston rod seated cross head serving as a piston of a double-acting charge pump, its with the working piston common piston rod in one of the inwardly lying working space is guided against the outward wall separating the pump chamber. With such a Machine is for a good seal of the piston rod sliding in the partition to care. For this purpose, the following device is provided according to the invention. Two sealing rings are located in an annular chamber provided in the partition , with a cross section in the shape of a right triangle side by side on the piston rod and are supported by two rings of the same cross-section, with their hypotenuses on those of the first-named rings and with one cathetus are on the ring wall of the chamber, pressed against the piston rod, through the pressure in the working space adjoining the partition wall on the one hand and those. in the pump space adjoining the partition wall, on the other hand, which Press yourself through fine bores in the two end walls of the chambers on the latter propagate.

In der Zeichnung zeigt Abb. 1 die gesamte Maschine im Querschnitt. Abb. 2 zeigt einen Schnitt durch die Trennwand. Abb.3 eine Draufsicht auf die Ringkammer und Abb.4 die Dichtungsringe.In the drawing, Fig. 1 shows the entire machine in cross section. Fig. 2 shows a section through the partition. Fig.3 is a top view of the annular chamber and Fig.4 the sealing rings.

Aus dem nichtgezeichneten Vergaser gelangt das frische Gemisch über den: Kanal f und die Saugventile g bzw. i in die beiden Räume c und lz der doppeltwirkenden Pumpe und von dort über die Druckventile o und L in die zum doppeltwirkenden Zweitaktzylinder führende Überströmleitung m. Der Ein- und der Auslaß des Arbeitszylinders wird von dem Arbeitskolben d gesteuert. Bei I und II sind die Zündkerzen angebracht.The fresh mixture passes over from the carburetor (not shown) the: channel f and the suction valves g and i in the two spaces c and lz of the double-acting Pump and from there via the pressure valves o and L to the double-acting two-stroke cylinder leading overflow line m. The inlet and outlet of the working cylinder is from controlled by the working piston d. At I and II the spark plugs are attached.

In der Trennwand zwischen dem Arbeitszylinder und der Pumpe ist eine Ringkammer mit Dichtungsringen vorgesehen. Mit q ist eine Platte bezeichnet, die auf der Trennwand aufliegt. Diese Platte weist ebenso wie die Abschlußwand zur Pumpe kleine Bohrungen r auf. Die Ringe 1, 2, 3 und 4 sind geteilt. Diese Ringe haben im Querschnitt die Form eines rechtwinkligen Dreiecks. Die Ringe 2 und 3 liegen mit der einen Kathete in voller Kammerhöhe an der Kolbenstange an und mit der anderen Kathete nebeneinander. Die Ringe i und 4 liegen mit ihren Hypotenusen auf denjenigen der letztgenannten Ringe 2 und 3 und mit der einen Kathete an der Ringwand der Kammer ebenfalls in voller Kammerhöhe an. Der Druck des einwärts liegenden Arbeitsraumes einerseits und des auswärts liegenden Pumpenraumes anderseits wirken, nun durch die feinen Bohrungen auf die zugeordneten Ringe i und 4,. die ihrerseits die Ringe 2 und 3 an die Kolbenstange anpressen.In the partition between the working cylinder and the pump is a Annular chamber provided with sealing rings. With q a plate is referred to, the rests on the partition. Like the end wall, this plate faces the pump small holes r. Rings 1, 2, 3 and 4 are divided. Have these rings in cross section the shape of a right triangle. Rings 2 and 3 are located with one catheter at full chamber height on the piston rod and with the other Side by side. The rings i and 4 lie with their hypotenuses on them the latter rings 2 and 3 and with one cathetus on the ring wall of the chamber also at full chamber height. The pressure of the inward working space on the one hand and the outwardly lying pump chamber on the other hand, now through the fine bores on the associated rings i and 4 ,. which in turn the rings Press 2 and 3 onto the piston rod.
