Abstract

A rotor (2) turns in a casing (1), of which the internal peripheral surface comprises several inlet and combustion chambers (4, 5) which are swept, during rotation of the rotor, by radially mobile slides (7, 8). Since the combustion chambers are considerably larger than the inlet chambers, the combustion gases can expand more than in a piston engine, thereby increasing the output of the engine not equipped with pistons.

Description

Kolbenloser Verbrennungsmotor Pistonless internal combustion engine

Bei den bekannten Kolbenmotoren und auch beim Wankelmotor sind Ansaugraum und Verbrennungsraum stets gleich gross. Betrachtet man die Verhältnisse beim Kolbenmotor, so sieht man, dass am Ende eines Arbeitstaktes, wenn der Kolben sich im unteren Totpunkt befindet, sich immer noch relativ heisse Verbrennungsgase unter hohem Druck im Zylinder befinden. Es ist klar, dass man weitere Energie gewinnen könnte, wenn es möglich wäre, den Kolben weiter nach unten zu führen und das Gas weiter expandieren zu lassen, m.a.W. wenn man den Verbrennungsraum vergrössern könnte.In the known piston engines and also in the Wankel engine, the intake chamber and combustion chamber are always the same size. If you look at the conditions of the piston engine, you can see that at the end of a work cycle, when the piston is at bottom dead center, there are still relatively hot combustion gases under high pressure in the cylinder. It is clear that more energy could be gained if it were possible to lower the piston further and let the gas expand further, m.W. if you could enlarge the combustion chamber.

Die Erfindung stellt sich die Aufgabe, diese beträchtliche Restenergie weiter auszunützen, also einen Motor zu schaffen, bei dem Ansaugraum und Verbrennungsraum voneinander getrennt sind und letzterer wesentlich grösser als der erstere ist. Die wesentlichen Merkmale der Erfindung ergeben sich aus dem Patentanspruch 1.The object of the invention is to further utilize this considerable residual energy, that is to say to create an engine in which the intake space and the combustion space are separated from one another and the latter is substantially larger than the former. The essential features of the invention result from patent claim 1.

Ein Auaführungsbeispiel des erfindungsgemässen Motors wird anhand der Zeichnung näher erläutert, in dieser zeigen:An exemplary embodiment of the motor according to the invention is explained in more detail with reference to the drawing, in which:

Fig. 1 einen Schnitt durch den Motor, senkrecht zur Rotorachse, Fig. 2 einen Schnitt längs der Linie II - II von Fig. 1. Im Gehäuse 1 ist ein auf der Welle 3 sitzender Rotor 2 untergebracht, wobei das Spiel zwischen diesen beiden Teilen möglichst gering gehalten ist. Auf der Innenseite des Gehäuses 1 sind mehrere Ansaugräume 4 und Verbrennungsräume 5 ausgespart. Die Verbrennungsräume 5 sind - vorzugsweise mehrfachgrösser als die Ansaugräume 4. In Drehrichtung ist hinter jedem Ansaugraum 4 eine Zünkerze 6 angebracht. Zum Abgrenzen der im Betrieb periodisch zu variierenden Volumina von Ansaug- und Verbrennungsräumen dienen die Schieber 7 und 8. Die Schieber sind in radialen Nuten des Rotors beweglich und sind mit seitlichen Zapfen 11 versehen, die in Nutenbahnen 9 bzw. 10 der Gehäuse- seitenwände geführt sind. Die Nutenbahnen verlaufen konzentrisch zur Rotorachse, und zwar so, dass der Verlauf der Bahn 9 dem peripheren Umrissverlauf der Ansaugräume entspricht und derjenige der Bahn 10 demjenigen der Verbrennungsräume. Damit wird erreicht, dass die Schieber 7 die Ansaugräume 4 exakt abdichtend überstreichen, wärend die Schieber 8 dasselbe beiden Verbrennungsräumen 5 bewirken. Zwischen je einem Paar von Schiebern ist am Rotor eine Abdichtlippe 14 vorgesehen, welche eine gasdichte Trennung zwischen Ansaug und Verbrennungsräumen gewährleistet.Fig. 1 shows a section through the motor, perpendicular to the rotor axis, Fig. 2 shows a section along the line II - II of Fig. 1. In the housing 1, a rotor 2 seated on the shaft 3 is accommodated, the play between these two parts is kept as low as possible. On the inside of the housing 1, several suction chambers 4 and combustion chambers 5 are left out. The combustion chambers 5 are - preferably several times larger than the intake chambers 4. In the direction of rotation, a spark plug 6 is fitted behind each intake chamber 4. The slides 7 and 8 are used to delimit the volumes of intake and combustion chambers which have to be varied periodically during operation. The slides are movable in radial grooves of the rotor and are provided with lateral pins 11 which run in groove tracks 9 and 10 of the housing side walls are. The groove tracks run concentrically to the rotor axis, in such a way that the course of the track 9 corresponds to the peripheral contour course of the intake spaces and that of the track 10 corresponds to that of the combustion spaces. It is thereby achieved that the slides 7 pass over the suction spaces 4 in an exactly sealing manner, while the slides 8 effect the same in both combustion spaces 5. Between each pair of sliders, a sealing lip 14 is provided on the rotor, which provides a gas-tight separation between the intake and combustion chambers guaranteed.

Zwischen den Schiebern jedes Taares ist am Rotorumfang eine Ausnehraung 13 vorgesehen die den Kompressionsraum darstellt, dessen Grosse so bemessen ist, dass sich ein vorgegebenes Kompressionsverhältnis ergibt. Nachfolgend wird die Arbeitsweise des Motors näher erläutert. Durch die Ansaugöffnung 12 wird das Gemisch im Fall eines Vergasermotors, bzw. die Luft eines Einspritzmotors, durch die Bewegung des Schiebers 7 angesaugt und in den Kompressionsraum 13 gepresst, anschliessend durch die Kerze 6 gezündet worauf die Verbrennung im Raum 5 erfolgt. Der Verbrennungsraum wird durch den Schieber 8 abgedichtet, auf den durch expandierenden Gase die tangential gerichtete Antriebskraft ausgeübt wird. Da dieser Raum 5 wesentlich grösser als der Ansaugraum 4 ist, kann die bei der Expansion frei werdende Energie wesentlich weiter als bei normalen Kolbenmotoren ausgenützt werden. Eine Rückwirkung des hohen Gadrucks im Verbrennungsraum auf den vorangehenden Ansaugraum wird durch die Abdichtlippe 14 verhindert.A recess 13 is provided on the rotor circumference between the slides of each pair, which represents the compression space, the size of which is dimensioned such that a predetermined compression ratio results. The operation of the engine is explained in more detail below. In the case of a carburetor engine or the air of an injection engine, the mixture is sucked in through the movement of the slide 7 and pressed into the compression space 13, then ignited by the candle 6, whereupon the combustion takes place in the space 5. The combustion chamber is sealed by the slide 8, on which the tangentially directed driving force is exerted by expanding gases. Since this space 5 is significantly larger than the suction space 4, the energy released during the expansion can be used much further than in normal piston engines. The sealing lip 14 prevents the high gad pressure in the combustion chamber from having an effect on the preceding intake space.

Im gezeigten Beispiel sind 12 Schieberpaare 7,8 in Winkelabständen von 30 vorhanden, so dass bei einer Umdrehung des Rotors in jedem VerbrennungsraumIn the example shown, there are 12 pairs of sliders 7, 8 at angular intervals of 30, so that in one combustion revolution of each rotor

12 Arbeitstakte stattfinden, insgesamt bei vier Ansaug- und Verbrennungs- räumen 48 Arbeitstakte, was einen sehr ruhigen und vibrationsfreien Lauf des Motors ergibt.12 work cycles take place, with a total of four intake and combustion chambers, 48 work cycles, which results in a very quiet and vibration-free running of the engine.

Es ist möglich mehrere der beschriebenen Mbtoreinheiten auf einer gemeinsamen Rotorwelle zu kombinieren. In einen solchen Fall wird man die Ansaug- und Verbrennungsräume der Motoreinheiten wihkelversetzt zueinander anordnen, wodurch sich eine weitere Erhöhung der Laufruhe des Motors erzielen lässt. Es ist für den Fachmann klar, dass sich der Motor auch als Dieselmotor ausbilden lässt. It is possible to combine several of the described door units on a common rotor shaft. In such a case, the intake and combustion chambers of the engine units will be arranged so as to be staggered from one another, thereby further increasing the smoothness of the engine. It is clear to the person skilled in the art that the engine can also be designed as a diesel engine.
