Abstract

The engine has a screw with a layer lying between a smaller head end (11) and a larger head end (15), assembled with a counter part of a screw part of a ball layer. Rotors are formed to engage into each other such that a tight hollow cavity forms combustion chambers. The rotors run into boreholes at the larger head end to form a ball segment at a bearing to tighten the screw at the smaller head end. An air inlet (16) is formed towards inclination of a screw winding so that the screw winding of the inlet is completely closed in a preset position.

Description

Die Erfindung betrifft einen Brennkraftmotor, der in der Art eines Schraubenkompressors aufgebaut ist. Eine ähnliche Maschine ist aus der Patentschrift DE 87685 bekannt und wurde als Dampfmaschine oder Pumpe benutzt. Als Neuerung wird hier jedoch durch spezielle Brennraumformung, Einspritzdüsen und Zündung ein Brennkraftmotor gebildet.The invention relates to an internal combustion engine which is constructed in the manner of a screw compressor. A similar machine is from the patent DE 87685 known and used as a steam engine or pump. As an innovation, however, an internal combustion engine is formed here by special combustion chamber molding, injectors and ignition.

Da er aus zwei sich entgegengesetzt drehenden konischen Schrauben (1, 2) in einem entsprechenden Gehäuse (3) mit zwei sich überschneidenden konischen Bohrungen besteht, wird er hier Schraubenmotor genannt.Because it consists of two counter-rotating conical screws ( 1 . 2 ) in a corresponding housing ( 3 ) with two overlapping conical holes, it is called screw motor.

Der Schraubenmotor ist sphärisch aufgebaut. Sowohl das kleine Kopfende (11) als das große Kopfende (15) und jede parallel dazwischen liegende Schicht einer Schraube ist zusammen mit dem Pendant der anderen Schraube Teil einer Kugelschicht. Alle Schichten weisen auf den gleichen Kugelmittelpunkt (M). Auch die Bohrungen, in denen die Rotoren laufen, sind am Kopfende (10) ebenfalls um die Lagerung herum kugelsegmentähnlich geformt, um den Brennraum am kleinen Kopfende abzudichten. Dieser sphärische Aufbau ist notwendig, um die Brennräume in jeder Drehposition untereinander und auch gegen das Gehäuse lückenlos abzudichten.The screw motor is spherical. Both the little headboard ( 11 ) as the big headboard ( 15 ) and each parallel layer of one screw together with the counterpart of the other screw is part of a spherical layer. All layers point to the same sphere center (M). Even the holes in which the rotors are running, are at the head ( 10 ) are also spherically shaped around the bearing so as to seal the combustion chamber at the small head end. This spherical structure is necessary to seal the combustion chambers in each rotational position with each other and also against the housing gapless.

Die Rotoren sind so geformt, dass sie ineinander greifen und dabei dichte Hohlräume bilden. Dies geschieht durch die in 1 dargestellte Form. Sie entsteht durch das gegenseitige Eingreifen von je drei Kreissegmenten auf zwei gegeneinander drehenden Achsen. Jedes Kreissegment hat eine Breite von genau einem Sechstel des Kreisumfangs. Der Achsenabstand beträgt dabei etwa den 1,5-fachen Radius. Der Lufteinlaß (16) befindet sich am kleinen Ende des Gehäuses, wo bei der Drehung der Schrauben die Hohlräume entstehen. An den Seiten ist der Lufteinlass in der Schräge den Gewindesteigungen nachgeformt (16), so dass das Schraubengewinde den Einlass zum Hohlraum verschließt. Sobald der Einlass geschlossen ist, wird Brennstoff eingespritzt oder zugegeben und gezündet. Die Einspritzdüsen (4) werden mit der Zündeinrichtung (5) ebenfalls parallel zur Gewindesteigung mittig zum eben geschlossenen Brennraum angeordnet. Im Verlauf der weiteren Drehung nimmt das Volumen des Brennraums nicht linear wie etwa in einem Zylinder, sondern kubisch zu, weil er nicht nur in der Länge, sondern auch in der Breite und Tiefe zunimmt.The rotors are shaped so that they interlock and form dense cavities. This is done by the in 1 illustrated form. It is created by the mutual intervention of three circle segments on two mutually rotating axes. Each circle segment has a width of exactly one sixth of the circumference. The axis distance is about 1.5 times the radius. The air intake ( 16 ) is located at the small end of the housing, where the cavities arise when the screws are turned. On the sides of the air inlet in the slope of the thread pitches is formed ( 16 ), so that the screw thread closes the inlet to the cavity. Once the inlet is closed, fuel is injected or added and ignited. The injectors ( 4 ) are used with the ignition device ( 5 ) Also arranged parallel to the thread pitch centered to the just closed combustion chamber. In the course of further rotation, the volume of the combustion chamber does not increase linearly, as in a cylinder, but cubically, because it increases not only in length, but also in width and depth.

So kann sich das Volumen im Verlauf von nur einer Drehung auf das 30-fache bis 100-fache vergrößern.So The volume can increase 30 times over a single turn enlarge up to 100 times.

Dadurch hat das heiße Verbrennungsgas die Möglichkeit, sich vollständig zu entspannen. Dies bedeutet auch eine nahezu vollständige Abgabe der Spannungsenergie und damit einen enormen Wirkungsgrad. Der Wirkungsgrad wird mittels eine vorgeschalteten Kompressors für die Verbrennungsluft noch weiter gesteigert. Das entspannte Abgas wird im weiteren Verlauf der Drehung dann drucklos ausgetrieben (7).As a result, the hot combustion gas has the opportunity to completely relax. This also means an almost complete release of the voltage energy and thus an enormous efficiency. The efficiency is further increased by means of an upstream compressor for the combustion air. The expanded exhaust gas is then expelled without pressure in the further course of the rotation ( 7 ).

Wegen der hohen Temperaturen im Brennraum ist es sinnvoll, den Schraubenkern gegen den brennraumseitigen Teil der Schraube mit einem die Wärme schlecht leitenden Material zu isolieren (13). Des weiteren ist wegen der zu erwartenden Wärmeausdehnung der brennraumseitige Teil der Schraube nur am kleineren Kopfende mit dem Schraubenkern formschlüssig zu verbinden (12), und nach dem großen Kopfende in axialer Richtung verschiebbar jedoch nicht drehbar. Dies kann durch eine Längsnut oder eine eckige Form erreicht werden. Auf diese Weise sorgt die gleichzeitige Längsausdehnung in axialer Richtung und die radiale Ausdehnung für eine gleichbleibende Abstand der Schraube zur konischen Bohrung und damit für gleichbleibende Dichtheit des Brennraums.Because of the high temperatures in the combustion chamber, it makes sense to isolate the screw core against the combustion chamber-side part of the screw with a material which conducts the heat poorly ( 13 ). Furthermore, due to the expected thermal expansion of the combustion chamber side part of the screw to connect positively only at the smaller head end with the screw core ( 12 ), and after the large head end in the axial direction displaceable but not rotatable. This can be achieved by a longitudinal groove or an angular shape. In this way, the simultaneous longitudinal extent in the axial direction and the radial extent for a constant distance of the screw to the conical bore and thus ensures a constant tightness of the combustion chamber.

Auf den Achsen sind noch zwei gegenläufige Zahnräder (8) befestigt, die für einen Gleichlauf der Schrauben sorgen.On the axes are still two counter-rotating gears ( 8th ), which ensure a synchronization of the screws.

Die Schraube und das Gehäuse können aus temperaturfester Keramik hergestellt werden.The Screw and the housing can be made more temperature resistant Ceramics are produced.

Die Vorteile dieses Motors ergeben sich aus den wenigen beweglichen Teilen, es werden keine Ventile, Kolben und Pleuel gebraucht. Der Brennraum ist im Verhältnis zur Gesamtgröße des Motors sehr groß, hiermit kann man also verhältnismäßig große Leistung erzielen. Durch die gute Ausnutzung der inneren Energie des Brenngases bei der vollständigen Entspannung ist ein hoher Wirkungsgrad zu erwarten. Da das Abgas drucklos entweicht, gibt es auch hier keine Energieverluste und es entsteht ein leiseres Auspuffgeräusch.The Advantages of this engine arise from the few moving ones Parts, no valves, pistons and connecting rods are needed. Of the Combustion chamber is in proportion to the overall size The engine is very large, so you can thus relatively large Achieve performance. By the good utilization of the internal energy of the fuel gas at the complete relaxation is a high efficiency expected. Since the exhaust gas escapes without pressure, There are no energy losses and a quieter one is created Exhaust noise.
