BrennkraftmaschineInternal combustion engine

Die Erfindung bezieht sich auf eine Zweitaktbrennkraftmaschine mit einem symmetrischen, freifliegenden Stufenkolben mit zwei ringförmigen, zentralen Vorverdichterkammern und axial außen liegenden Brennkammern. Eine derartige Maschine ist bekannt. Die Schwierigkeit bei Freikolbenmaschinen liegt aber darin, daß sie sich nur indirekt anwenden lassen. Eine mechanische Arbeit kann unmittelbar nicht ausgeführt werden.The invention relates to a two-stroke internal combustion engine with a symmetrical, free-flying stepped piston with two annular, central pre-compression chambers and axially external combustion chambers. Such a one Machine is known. The difficulty with free piston machines is that they are only indirect let apply. Mechanical work cannot be carried out immediately.

Demgegenüber wird mit der Erfindung vorgeschlagen, die Brennkammern ringförmig zu gestalten, wobei der Kolben über die Brennkammern und das Gehäuse axial hinaus verlängert ist. Dadurch ist es möglich, bei einer vorteilhaft symmetrisch gestalteten und arbeitenden Maschine eine beliebige Arbeit, beispielsweise eine Verdichterarbeit, durch den an beiden Seiten frei zugänglichen Stufenkolben ausführen zu lassen.In contrast, the invention proposes the combustion chambers to be annular in shape, the piston being extended axially beyond the combustion chambers and the housing. This makes it possible, with an advantageously symmetrically designed and working machine, to do any work, For example, a compression work can be carried out through the stepped piston, which is freely accessible on both sides.

Gemäß einer Ausgestaltung ist der Kolben hohl, vorzugsweise konisch hohl. Der hohle Innenraum dient zunächst der Kühlung. Er kann aber auch als Arbeitsteil der Maschine nutzbar gemacht werden. Die Konizität des hohlen Innenraums schafft die Möglichkeit, ein beliebiges Medium zu verdichten oder zu fördern. Bei niedrigen Frequenzen wird es notwendig sein,According to one embodiment, the piston is hollow, preferably conical hollow. The hollow interior is initially used for cooling. But it can also be used as a working part of the machine will. The conicity of the hollow interior creates the possibility of compressing or closing any medium support financially. At low frequencies it will be necessary to

ein in Strömungsrichturig sich öffnendes Flatterventil vorzusehen. Bei höheren Frequenzen, beispielsweise ab 15.000 Schwingungen, die mit der Maschine ohne weiteres erreichbar sind, erfolgt die Mediumsbewegung bzw. Mediumsbeschleunigung durch die Konizität des Hohlraums auch ohne Flatterventil.a flutter valve that opens in the direction of flow is to be provided. At higher frequencies, for example from 15,000 Vibrations that can be easily achieved with the machine are, the medium movement or medium acceleration takes place due to the conicity of the cavity even without a flutter valve.

Gemäß beiliegender Zeichnung ist bei einem Ausführungsbeispiel der Maschine ein Zylinder mit einer Zyiinderwand 12 vorhanden. Im Inhenraum befindet sich ein stufenförmiger, freifliegender Kolben 14. Die Stufen werden im wesentlichen durch zwei Ringscheiben 18 gebildet. Der Zylinderinnenraum weist ein Mittelstück 22 auf, in dem der Kolben 14 mittels Kolbenringen 40 geführt und abgedichtet ist. Symmetrisch an das Mittelstück 22 schließen sich rechts und links ringförmige Ladekammern 24 an. Jenseits der Kolbenstufen 18 befinden sich axial nach außen zwei Brennkammern 26. Das Brenngas tritt über Einiaßschlitze 30 in die Ladekammern 24 ein. über Äuslaßschlitze 32 und durch Überströmkanäle 34 gelangt das vorverdichtete Gas in Einlaßschlitze 36 und von dort in die Brennkammern 26. Nach der Zündung und Expansion verlassen die verbrannten Gase nach dem Prinzip der bekannten Querstromspülung die Brennkammern 26 durch die AuslaßschlitzeAccording to the accompanying drawing, in one embodiment of the machine a cylinder with a cylinder wall 12 available. In the interior there is a step-shaped, free-flying piston 14. The stages are essentially formed by two annular disks 18. The cylinder interior has a center piece 22 in which the piston 14 by means of Piston rings 40 is guided and sealed. Symmetrically on the middle piece 22 close to the right and left annular Loading chambers 24. Beyond the piston steps 18 there are two combustion chambers 26 axially outward. The fuel gas enters the loading chambers 24 via inlet slots 30. above Äuslaßschlitze 32 and through overflow channels 34 get the precompressed gas into inlet slots 36 and from there into combustion chambers 26. Leave after ignition and expansion the burned gases according to the principle of the well-known cross-flow purging the combustion chambers 26 through the exhaust ports

Als Zündhilfe ragen Zündkerzen 32 in die Brennkammern 26 hinein.Spark plugs 32 protrude into combustion chambers 26 as an ignition aid into it.

Die axial über die Brennkammern 26 sich hinaus erstreckenden Verlängerungen 50, 52 des Kolbens 14 werden mittels Kolbenringen 40 geführt und abgedichtet. Auch die ringförmige Stufe 18 des Kolbens 14 weist Kolbenringe 40 auf.The axially extending beyond the combustion chambers 26 also Extensions 50, 52 of the piston 14 are guided and sealed by means of piston rings 40. Even the ring-shaped Step 18 of piston 14 has piston rings 40.

In dem dargestellten Ausführungsbeispiel weist der Kolben einen hohlen Innenraum 48 auf, der konisch ausgebildet istIn the illustrated embodiment, the piston a hollow interior 48 which is conical in shape
