Abstract

The engine comprises cylinder sections (11, 12) provided with feed chambers (15, 16) for additional fresh air. The two outer rings (4a, 4c) acting as pistons, draw in fresh air through intake ports (17a, 18b) and force that air to enter combustion chambers (13, 14) through communication ducts (9a, 9b) and ports (19, 20). The middle ring (4b) is intended for the fresh gas supply of the combustion chambers (13, 14). The radial grooves (21, 22) for fresh air are provided at a shorter distance from the ports (19, 20) than the radial grooves (8a, 8b) for fresh gas. Burned and expanded gas is first exhausted from the combustion chambers (13, 14) by fresh gas; then, the combustion chambers (13, 14) are filled with fresh gas and fresh air. Thus, exhausting unburned gas together with burned gas is avoided and an improved combustion is provided within the combustion chambers (13, 14).

Der dargestellte Zweitakt-Schwingkolbenmotor weist wenigstens einen hin und her bewegbaren Kolbenkörper 1 auf, der von einem aus mehreren parallelen, koaxial zusammengeschraubten Teilen bestehenden Hohlzylinder 2 umgeben ist (Fig. 1) . Der Kolbenkörper 1 ist in Wirkverbindung mit einem in der Zeichnung nicht dargestellten speziellen Kurbelgetriebe, dessen Kurbelbolzen in einem rechtwinklig zur Längsachse des Kolbenkörpers 1 schwingenden Gleitzapfen gelagert ist, wobei das den Gleitzapfen aufnehmende Getriebeteil mit dem Kolbenkörper 1 fest verbunden ist. Der Gleitzapfen soll die radialen Kraftkomponenten auf den Kolbenkörper 1 durch Umgehung der Pleuelstange möglichst klein halten.The two-stroke oscillating piston engine shown has at least one reciprocating piston body 1, which is surrounded by a hollow cylinder 2 consisting of several parallel, coaxially screwed parts (FIG. 1). The piston body 1 is operatively connected to a special crank mechanism (not shown in the drawing), the crank pin of which is mounted in a sliding pin which swings at right angles to the longitudinal axis of the piston body 1, the gear part receiving the sliding pin being firmly connected to the piston body 1. The sliding pin should keep the radial force components on the piston body 1 as small as possible by bypassing the connecting rod.
Der Kolbenkörper 1 weist eine zylindrische Welle 3 auf. Auf dieser sind drei zylinderförmige, als Kolben wir kende Ringe 4a, 4b, 4c verstiftet. Der Hohlzylinder 2 ist inbezug auf seine Längsmitte symmetrisch, ebenso das mittlere Hohlzylinderstück 5. Die axiale Bohrunng dieses Hohl zylinderstückes 5 wird durch den mittleren Ring 4b in zwei Frischgasvorschubräume 6a, 6b unterteilt. Symmetrisch zu seiner Längsmitte weist das Hohlzylinderstück 5 zwei nebeneinander angeordnete Frischgaseinlassöffnungen 7a, 7b auf. Die äusseren Enden der Vorschubräume 6a, 6b des Hohl zylinderstückes 5 sind durch je eine Uebergangsnut 8a, 8b mit einem linken oder einem rechten Frischgasübergangskanal 9a, 9b verbunden. An beiden Stirnseiten des mittleren Hohl zylinderstückes 5 sind gleiche Zwischenwände 10a, 10b mit einem durchgehenden Teil des entsprechenden Frischgasüber gangskanals 9a, 9b vorgesehen (Fig. 3, 5) . Anschliessend an diese beiden Zwischenwände 10a, 10b sind zur Längsmitte des Hohlzylinders 2 zwei symmetrische Arbeitszylinderstücke 11, 12 eingebaut, deren axiale Bohrungen durch die beiden äusseren Ringe 4a, 4c des Kolbenkörpers 1 in je einen inneren Raum als Verbrennungsraum 13, 14 und je einen äusseren Raum als Frischluftvorschubraum 15, 16 unterteilt sind. Mindestens annähernd in der Längsmitte dieser Arbeitszylinderstücke 11, 12 sind je zwei radiale Oeffnungen vorgesehen. Die äusseren Oeffnungen dienen als Frischlufteinlassöffnungen 17a, 18b, die inneren Oeffnungen als Abgasauslassöffnungen 17b, 18a.The piston body 1 has a cylindrical shaft 3. On this are three cylindrical, like pistons we pending rings 4a, 4b, 4c pinned. The hollow cylinder 2 is symmetrical with respect to its longitudinal center, as is the middle hollow cylinder piece 5. The axial bore of this hollow cylinder piece 5 is divided by the middle ring 4b into two fresh gas feed spaces 6a, 6b. Symmetrical to its longitudinal center, the hollow cylinder piece 5 has two fresh gas inlet openings 7a, 7b arranged side by side. The outer ends of the feed spaces 6a, 6b of the hollow cylinder piece 5 are each connected by a transition groove 8a, 8b to a left or a right fresh gas transition channel 9a, 9b. On both end faces of the central hollow cylinder piece 5, the same partition walls 10a, 10b are provided with a continuous part of the corresponding fresh gas transition channel 9a, 9b (Fig. 3, 5). Following these two intermediate walls 10a, 10b, two symmetrical working cylinder pieces 11, 12 are installed to the longitudinal center of the hollow cylinder 2, the axial bores of which through the two outer rings 4a, 4c of the piston body 1 each in an inner space as combustion space 13, 14 and one outer space Space as fresh air feed space 15, 16 are divided. At least approximately in the longitudinal center of these working cylinder pieces 11, 12, two radial openings are provided. The outer openings serve as fresh air inlet openings 17a, 18b, and the inner openings serve as exhaust gas outlet openings 17b, 18a.
Diametral gegenüber den Abgasauslassöffnungen 17b, 18a sind radiale Oeffnungen 19, 20 vorgesehen, welche die Frischgasübergangskanäle 9a, 9b zeitweise mit den Verbrennungsräumen 13, 14 verbinden. An ihren äusseren Enden sind die Fristluftvorschubräume 15, 16 durch radiale Uebergangsnuten 21, 22 mit den Frischgasübergangskanälen 9a, 9b verbunden (Fig. 2, 4). Die beiden Arbeitszylinderstücke 11, 12 sind in axialer Richtung durch je eine Aussenwand 23, 24 abgeschlossen. Bei jeder Kolbenbewegung nach links expandiert das entzündete Gasgemisch im Verbrennungsraum 13 zwischen der linken Zwischenwand 10a und dem linken äusseren Ring 4a. Anschliessend wird durch diesen linken äusseren Ring 4a Frischluft und durch den mittleren Ring 4b Frischgas zum Ausstossen des verbrannten, expandierten Gases vorgeschoben, während der äussere rechte Ring 4c Frischgas mit Zusatzfrischluft im Verbrennungsraum 14 komprimiert. Bei der Kolbenbewegung nach rechts wiederholen sich die entsprechenden Vorgänge sinngemäss.Radial openings 19, 20 are provided diametrically opposite the exhaust gas outlet openings 17b, 18a, which temporarily connect the fresh gas transition channels 9a, 9b to the combustion chambers 13, 14. At their outer ends, the deadline air feed spaces 15, 16 are connected to the fresh gas transition channels 9a, 9b by radial transition grooves 21, 22 (FIGS. 2, 4). The two working cylinder pieces 11, 12 are each closed off in the axial direction by an outer wall 23, 24. With each piston movement to the left, the ignited gas mixture in the combustion chamber 13 expands between the left intermediate wall 10a and the left outer ring 4a. Fresh air is then advanced through this left outer ring 4a and fresh gas through the middle ring 4b to expel the burned, expanded gas, while the outer right ring 4c compresses fresh gas with additional fresh air in the combustion chamber 14. When the piston moves to the right, the corresponding processes are repeated analogously.
Wie aus Fig. 1 ersichtlich, ist der Abstand der radialen Frischluftübergangsnuten 21, 22 zu den radialen Uebergangsöffnungen 19, 20 kleiner als der Abstand der radialen Frischgasübergangsnuten 8a, 8b zu den radialen Uebergangsöffnungen 19, 20. Dies hat zur Folge, dass zunächst Frischluft zum Ausstossen des verbrannten Gases verwendet wird, wobei anschliessend Frischgas zusammen mit Zusatzfrischluft den Verbrennungsraum 13 füllen. Dabei wird verhindert, dass mit dem verbrannten Gas auch noch unverbranntes Frischgas ausgestossen wird. Zudem bewirkt die Zugabe von Frischluft eine vollkommenere Verbrennung des Brennstoffes im Verbrennungsraum. Zum Ausgleich des Drehmoments können mehrere Hohlzylinder 2 und Kolbenkörper 1 vorgesehen sein. As can be seen from FIG. 1, the distance between the radial fresh air transition grooves 21, 22 and the radial transition openings 19, 20 is smaller than the distance between the radial fresh gas transition grooves 8a, 8b and the radial transition openings 19, 20. This has the consequence that fresh air is initially supplied to the Ejection of the burned gas is used, with fresh gas then filling the combustion chamber 13 together with additional fresh air. This prevents the unburned fresh gas from being ejected with the burned gas. In addition, the addition of fresh air results in a more complete combustion of the fuel in the combustion chamber. A plurality of hollow cylinders 2 and piston bodies 1 can be provided to compensate for the torque.
