Abstract

The rotationally reciprocating piston engine comprises a cylindrical housing (1) with two piston members (2, 3) on a central shaft. Each is independently reciprocated by a crank via a swivel lever coupled by a connection rod to a common crankshaft. The pistons define four combustion chambers (9-12) between them, served by two inlet ports (35, 36) and two outlet ports (37, 38) in the housing wall, so that there are eight working strokes for each revolution of the crankshaft. Sealing may be by strips in grooves in the piston. These strips are in contact with the cylindrical wall and the end walls of the housing, with a seal ring in an annular groove concentric with the shaft on which the pistons rotate.

Description

Betr.: Patentanmeldung einer Gegenkolben-Verbrennungs- Re: patent application for an opposed piston combustion

kraftmaschine mit vierfacher Kolbenbeaufschlagung. engine with fourfold piston loading.

Beschreibun Die bekannteste Gegenkolben-Verbrennungskraftmaschine ist wohl der von Professor Junkers entwickelte Zweitakt-Dieselflugmotor Wegen des guten thermischen Wirkungsgrades, der unsymetrischen Gleichstromspülung und des ausgezeichneten Massenausgleichs war der Bauaufwand ein negativer Faktor. Description The best-known opposed piston internal combustion engine is probably the two-stroke diesel aircraft engine developed by Professor Junkers because of the good thermal efficiency, asymmetrical direct current purging and des excellent mass balance, the construction effort was a negative factor.

Ziel unserer Überlegung war, die guten Eigenschaften des Gegenkolbenprinzips mit geringerem Bauaufwand zu erreichen. The aim of our consideration was the good properties of the opposed piston principle to achieve with less construction effort.

-Ufn eine größere Energiedichte zu erzeugen, wurde das von uns entwickelte Antriebssystem als vierfache Kolbenbeaufschlagung ausgelegt.-In order to generate a greater energy density, this was developed by us Drive system designed as fourfold piston loading.

In einem runden Gehäuse 1 ( Fig, 1 ) schwingen zwei gegenläufige Kolben 2 und 3 ( Fig, 1 ), gesteuert durch die Kurbelwelle 4 ( Fig. 2 ), zwei Pleuelstangen 5 und 6 ( Fig. 2 und zwei Schwinghebel 7 und 8 ( Fig. 2 ) um den Mittelpunkt und bilden die Arbeitsräume 9, 10, 11, 12 ( Fig, 1 ). In a round housing 1 (Fig, 1), two oscillating in opposite directions Pistons 2 and 3 (Fig, 1), controlled by the crankshaft 4 (Fig. 2), two connecting rods 5 and 6 (Fig. 2 and two rocker arms 7 and 8 (Fig. 2) around the center and form the working spaces 9, 10, 11, 12 (Fig, 1).

Bei Jeder Kurbelwellenumdrehung ergeben sich vier Zündungen und acht Arbeitstakte. For every revolution of the crankshaft there are four ignitions and eight Work cycles.

Der Gaswechsel kann nach einem unsymetrischen Steuerdiagramm arbeiten, so daß auch eine Aufladung möglich ist. The gas exchange can work according to an asymmetrical control diagram, so that charging is also possible.

Weil die Kolben 2 und 3 ( Fig. i ) um den Mittelpunkt schwingen, wird das Gehäuse 1 ( Fig. 1 ) nicht zur Führung der Kolben 2 und 3 ( Fig. 1 ) herangezogen, Die Kolben 2 und 3 ( Fig. 1 ) haben Je eine Aussparung 13 (Fig. 2 ), so daß die Kolben 2 und 3 ( Fig. 1 ) mit den Gehäuseseiten 14 und 15 ( Fig. 2 ) abschließen. Because pistons 2 and 3 (Fig. I) swing around the center, If the housing 1 (Fig. 1) is not used to guide the pistons 2 and 3 (Fig. 1), The pistons 2 and 3 (Fig. 1) each have a recess 13 (Fig. 2), so that the Complete piston 2 and 3 (Fig. 1) with the housing sides 14 and 15 (Fig. 2).

Die Schwinghebel 7 und 8 ( Fig. 2 ) und die Kurbelwelle 4 ( Fig. 2 ) können so ausgelegt werden, daß der Weg kleiner als der Kolbenweg ist. The rocker arms 7 and 8 (Fig. 2) and the crankshaft 4 (Fig. 2) can be designed so that the path is smaller than the piston path.

Alle Bauteile sind so dimensioniert, daß für die Unterbringung der Dichtelemente viel Platz zur Verfügung steht. All components are dimensioned so that for accommodating the Sealing elements a lot of space is available.

Die Stirndichtleiste 16 ( Fig. 3 ) hat an den beiden Enden Abschrägungen 17 und 18 ( Fig. 3 ). The front sealing strip 16 (Fig. 3) has bevels at both ends 17 and 18 (Fig. 3).

Die Seitendichtleisten 19 und 20 ( Fig. 3 ) haben an einem Ende Je eine-Abschrägung 21 und 22 ( Fig. 3 ) und drücken durch Federkraft in den Dichtsplinten 23 und 24 ( Fig. 3 die Stirndichtleiste 16 ( Fig. 3 ) an das Gehäuse. The side sealing strips 19 and 20 (Fig. 3) have each at one end a bevel 21 and 22 (Fig. 3) and press by spring force in the split pins 23 and 24 (Fig. 3, the front sealing strip 16 (Fig. 3) on the housing.

Die Seitendichtleisten 25, 26, 27, 28 ( Fig. 4 ) fassen mit einem Ende in die Nuten des Dichtsplints 29 ( Fig, 4 ). The side sealing strips 25, 26, 27, 28 (Fig. 4) grasp with a End into the grooves of the sealing pin 29 (Fig, 4).

Die Wellendichtleisten 30 und 31 ( Fig. 4 ) fassen in die Nuten des Dichtsplints 29 ( Fig. 4 ). The shaft sealing strips 30 and 31 (Fig. 4) engage in the grooves of the Sealing splints 29 (Fig. 4).

Die Wellendichtleiste 32 ( Fig. 4 ) hat die Form eines Ringes. The shaft sealing strip 32 (Fig. 4) has the shape of a ring.

Welle 33 ( Fig. 2 ), Einlaßöffnungen 35 u.36 ( Fig. 1 ), Kurbelgehäuse 34 ( Fig. 2 ), Auslaßöffnungen 37 u.38 ( Fig. 1 ). Shaft 33 (Fig. 2), inlet openings 35 and 36 (Fig. 1), crankcase 34 (Fig. 2), outlet openings 37 and 38 (Fig. 1).

Das Antriebssystem benötigt keinen Ventiltrieb und keine Zylinderköpfe. Es zeichnet sich durch hohe Energiedichte, durch geringen Bauaufwand, durch leichte, steife und kompakte Bauweise aus und kann als Dieselverfahren bzw. mit Fremdzündung für alle fossilen Brennstoffe ausgelegt werden. Das Antriebssystem ist für viele Anwendungsgebiete und Größenordnungen interessant. The drive system does not require a valve train or cylinder heads. It is characterized by high energy density, by low construction costs, by light, stiff and compact design and can be used as a diesel process or with external ignition designed for all fossil fuels. The propulsion system is for many Areas of application and orders of magnitude interesting.
