Abstract

The rotor body (2) is rotatably located, displaced axially to the engine housing, and is provided with segments which are U-shaped and enclosed by sprung, wear-resistant U-shaped piston rings. Sealing of the segments in channels (5) is supported by pressure channels (10). In the chamber of the smallest volume between the segments, basic body (2) and housing (3) a flow channel is located in the air movement direction which allows compressed air from one or two adjoining compressors to flow into the combustion chamber. In the combustion chamber is an injection nozzle feeding fuel continuously, and which is so affected by the compressed air that a gas-air mixt. is produced, with combustion occurring in the expansion area, causing the engine system to be driven. USE/ADVANTAGE - For Otto or diesel engines, to convert combustion energy into rotary movement directly, to optimise compression of gas-air mixt. with combustion of the mixt. over a longer period, permitting better use of energy.

Titel der ErfindungTitle of the invention

Verbrennungsmotor zur kontinuierlichen Verbrennung des Kraftstoffes bei direkter Umwandlung in die Drehbewegung.Internal combustion engine for the continuous combustion of the Fuel with direct conversion into rotary motion.

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft einen Verbrennungsmotor mit hohem Wirkungsgrad und einer kontinuierlichen Verbrennung eines in den Brennraum eingespritzten Kraftstoffes, wodurch weniger Aufwand zur Schalldämpfung erforderlich wird und die ständige Zündung eines Verbrennungstaktes wie bei den Ottomotoren entfällt. Der Kraftstoff hat die Möglichkeit, über einen längeren Zeitintervall zu verbrennen. Dabei wird mehr Energie an die Antriebswelle übertragen. Er arbeitet ohne Kolben im herkömmlichen Sinne und ohne Ventile. Die Verbrenungsenergie wird sofort in eine Rotationsbewegung umgewandelt.The invention relates to an internal combustion engine with a high Efficiency and continuous combustion of a fuel injected into the combustion chamber, thereby less noise attenuation effort is required and the constant ignition of a combustion cycle as with the Gasoline engines are eliminated. The fuel has the possibility burn over a longer period of time. Doing so transmit more energy to the drive shaft. Developed without pistons in the traditional sense and without valves. The combustion energy is immediately converted into a rotational movement.

Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions

Motore, die mit Brennstoffen betrieben werden, sind die hinreichend bekannten Otto- oder Dieselmotore, bei denen die Verdichtung des Gas-Luftgemisches durch zylindrische Kolben erfolgt und die Verbrennung über Kolben und Kurbelwelle die notwendige Drehbewegung realisiert. Typisch ist dabei, daß die lineare Bewegung in eine Rotationsbewegung umgewandelt wird, wobei der Kolben in der Hubbewegung ständig beschleunigt und abgebremst wird.Engines that run on fuels are sufficient known gasoline or diesel engines, in which the compression of the gas-air mixture is carried out by cylindrical pistons and combustion via pistons and crankshafts the necessary Rotary movement realized. It is typical that the linear movement is converted into a rotational movement, whereby the piston constantly accelerates and brakes in the stroke movement becomes.

Eine Alternative, die sich jedoch nicht durchsetzen konnte, stellte der Drehkolbenmotor von Wankel dar. Weiterhin bekannte Arten von Verbrennungsmotoren sind Turbinen.An alternative that could not prevail, represented the rotary piston engine from Wankel.

Darlegung des Wesens der ErfindungState the nature of the invention

Es gibt zwei Varianten der Realisierung.There are two types of implementation.

Variante 1version 1

Auf einer durchgehenden Vielkeilwelle 1 sind rotationssymmetrische Teile 2 mit einem Querschnitt wie in Fig. 1 sichtbar aufgesteckt.On a continuous spline shaft 1 , rotationally symmetrical parts 2 with a cross section as in FIG. 1 are visibly attached.

Dazwischen und an den Stirnseiten befinden sich gechliffene Scheiben als Gehäuse 3 ausgebildet, deren Querschnitt wie im Bild 1 sichtbar ist und in denen sich Dichtungsringe 4 befinden. Gemäß Fig. 2 sind in dem Teil 2 in der Tiefe begrenzte Nuten 5 eingearbeitet (die Anzahl muß optimiert werden). In diesen Nuten gleiten Segmente 6, die sehr leicht sein sollten, deren Querschnitt in Fig. 3 dargestellt ist. In between and on the end faces are ground disks designed as a housing 3 , the cross section of which is visible as in Figure 1 and in which there are sealing rings 4 . According to FIG. 2, deep grooves 5 are incorporated in part 2 (the number must be optimized). In these grooves slide segments 6 , which should be very light, the cross section of which is shown in Fig. 3.

Über den U-förmigen Umfang (einseitig offen) sind ein oder mehrere Kolbenringe 7 aus federndem, verschleißfestem, gut gleitfähigem Material aufgesteckt. Unter den äußeren Kolbenringen befindet sich ein gewellter Federblechstreifen 8. Im Hohlraum der Segmente 6 steckt eine Feder 9, vorzugsweise aus hitzebeständiger Keramik, welche die Segmente 6 immer nach außen drücken. Der Kanal 10 in Fig. 4 und die Zentrifugalkraft unterstützt die Schubkraft der Feder bei Betrieb des Motors, insbesondere in dem Bereich, wo eine hohe Abdichtung erforderlich ist. Über axiale Rohrleitungen (Bohrungen) und Kanäle 11 werden die Segmente geschmiert.Over the U-shaped circumference (open on one side) one or more piston rings 7 made of resilient, wear-resistant, easily slidable material are attached. A corrugated spring steel strip 8 is located under the outer piston rings. In the cavity of the segments 6 there is a spring 9 , preferably made of heat-resistant ceramic, which always press the segments 6 outwards. The channel 10 in FIG. 4 and the centrifugal force support the thrust force of the spring during operation of the engine, especially in the area where a high seal is required. The segments are lubricated via axial pipes (bores) and channels 11 .

Das Gehäuse 3 ist exzentrisch zur Mittelachse der Vielkeilwelle versetzt angebracht, wie in Fig. 1 sichtbar. An der Stelle des kleinsten Volumens zwischen den Segmenten 6 des Gehäuses 3 und Teil 2, wie in Fig. 2 sichtbar, befindet sich die Einspritzdüse 12, in die der Treibstoff eingespritzt wird, der bei dessen Verbrennung den Körper 2 und damit die Vielkeilwelle in Drehung versetzt, wobei der Ruck des verbrannten Gas-Luftgemisches gleichzeitig die Segmente 6 über die Kanäle 10 nach außen drückt, damit sie besser abdichten. Im gegenüberliegenden Bereich ist der Umfang des Gehäuses schlitzförmig durchbrochen, durch die die verbrannten Gase durch den Auspuff 13 abgeleitet werden.The housing 3 is mounted eccentrically to the central axis of the splined shaft, as can be seen in FIG. 1. At the location of the smallest volume between the segments 6 of the housing 3 and part 2 , as can be seen in FIG. 2, there is the injection nozzle 12 , into which the fuel is injected which, when burned, rotates the body 2 and thus the splined shaft offset, the jerk of the burned gas-air mixture simultaneously pushes the segments 6 out through the channels 10 so that they seal better. In the opposite area, the circumference of the housing is perforated in a slit shape, through which the burned gases are discharged through the exhaust 13 .

In einem danebenliegenden Gehäuse, wie in Fig. 2 sichtbar, befindet sich die gleiche Konstruktion, die zum Ansaugen und Verdichten der Luft dient, jedoch zur Vergrößerung der Verdichtung breiter ausgeführt sein kann oder es können beiderseitig gleiche Gehäuse angebracht werden.In an adjacent housing, as can be seen in FIG. 2, there is the same construction, which is used for drawing in and compressing the air, but can be made wider to increase the compression, or the same housing can be attached to both sides.

Diese haben die Aufgabe nach dem gleichen umgekehrt wirkendem Prinzip über Ansaugkanal 13, in Fig. 5 sichtbar, Luft anzusaugen und zu verdichten. Die Figur zeigt, daß die Kanäle 14 auf der gegenüberliegenden Seite der Segmente eingebracht sind. Sie haben die Aufgabe, die Abdichtung der Segmente 6 bei der Verdichtung der Luft zu verbessern. Wie in Fig. 2 gezeigt, befinden sich in Drehrichtung vor der Kraftstoffeinspritzkammer der Überströmkanal 15.They have the task of sucking in and compressing air according to the same principle, acting in reverse, via intake duct 13 , visible in FIG. 5. The figure shows that the channels 14 are introduced on the opposite side of the segments. They have the task of improving the sealing of the segments 6 when the air is compressed. As shown in FIG. 2, the overflow channel 15 is located upstream of the fuel injection chamber in the direction of rotation.

Wenn sich der Motor dreht, wird kontinuierlich (je mehr Segmente desto gleichmäßiger) verdichtete Luft der Kraftstoffeinspritzkammer 16 zugeführt. As the engine rotates, compressed air is continuously supplied to the fuel injection chamber 16 (the more segments the more uniform).

Die Segmente 6, auch wenn sie aus leichtem Material bestehen, verschieben durch die exzentrische Anordnung den Schwerpunkt von der Mittelachse. Um ein Fibrieren des Motors zu vermeiden, sollte auf der gleichen Welle noch ein gleiches System aufmontiert werden, nur mit einem um 180° gedrehtem Gehäuse.The segments 6 , even if they are made of light material, shift the center of gravity from the central axis due to the eccentric arrangement. In order to prevent the motor from vibrating, the same system should be mounted on the same shaft, only with a housing rotated by 180 °.

Variante 2Variant 2

Eine andere, jedoch komplizierter herstellbare Variante des Gehäuses sichert das Ansaugen und Verdichten der Luft, das Verbrennen des eingespritzten Kraftstoffs und Ausstoßen der verbrannten Gase bei einer Umdrehung oder mehrmals bei einer Umdrehung in einem Gehäuse je nach Ausführung des Gehäuses. In Fig. 6 ist das Wirkprinzip für zwei Verbrennungsstationen pro Umdrehung erkennbar.Another, but more complicated to produce variant of the housing ensures the suction and compression of the air, the combustion of the injected fuel and the expelling of the burned gases in one revolution or several times in one revolution in a housing, depending on the design of the housing. The principle of action for two combustion stations per revolution can be seen in FIG. 6.
