Gegenstand der Erfindung ist eine luftgekühlte Verbundverbrennungskraftmaschine mit sich drehenden Laufrädern für flüssige oder gasförmige Brennstoffe (aber auch für Dampf), bei der die sämtlichen (hier drei) Laufräder (kreisenden Kolben) zu einem einzigen Hohlkörper ausgestaltet und vereinigt sind, so daß die Luft kühlend hindurchstreichen kann, Zwischenwände der Gehäuse völlig wegfallen ίο und die Arbeit der Gase beim Überströmen von einem Laufrade zum anderen durch Reaktion teilweise nutzbar gemacht wird. Das Gehäuse ist in so viel Einzelabteilungen > getrennt, wie Laufräder vorhanden sind, und die Luft kann ' zwischen den Einzelgehäusen auch seitlich in den Hohlraum der Laufräder eindringen, so" daß eine allseitige Luftkühlung ermöglicht wird. Die Pfeile in Fig. 1 zeigen den Weg der Kühlluft.The invention relates to an air-cooled compound internal combustion engine with rotating impellers for liquid or gaseous fuels (but also for steam), in which all (here three) impellers (rotating pistons) form a single hollow body are designed and united so that the air can pass through cooling, Partition walls of the housing are completely omitted ίο and the work of the gases when flowing over is made partially usable by reaction from one impeller to the other. That Housing is divided into as many individual compartments as there are impellers, and the air can 'between the individual housings laterally into the cavity of the impellers penetrate, so that air cooling on all sides is made possible. The arrows in FIG. 1 show the way of the cooling air.

bilden Gehäuse a¹ und Laufrad δ¹ zusammen mit acht Widerlagschiebern d das System 1, die Hochdrückmaschine, Gehäuse a² und Laufrad δ² zusammen mit ihren acht Widerlagschiebern System 2, die Mitteldruckmaschine, Gehäuse a³ und Laufrad δ³ zusammen mit ihren acht Widerlagschiebern System 3, die Niederdruckmaschine. Jedes Laufrad hat drei als Kolben wirkende Vorsprünge c. Die Widerlagschieber sind federbelastet, können aber auch wie bei bekannten Maschinen gesteuert werden; sie sind hohl und ermöglichen so eine Luftkühlung, die nötigenfalls dadurch verstärkt werden kann, daß man die Führungen der Schieber durch zwei Klappenventile abschließt, so daß der Widerlagschieber wie eine Pumpe beim Niedergehen durch das eine Ventil Kühlluft ansaugt, beim Hochgehen durch das andere ausstößt. Die Kühlung der Laufräder und Gehäuse geschieht durch einen Luftstrom, der, zwischen den Laufradspeichen der Hochdruckmaschine und seitlich zwischen den Gehäuseteilen eindringend, die Maschine durchstreicht und bei dieser durch die schräggestellten flachen Speichen der Niederdruckmaschine (Fig. ι und 5), welche nach Art eines Sauggebläses wirken, erzeugt wird. Man kann diesen Luftstrom auch durch komprimierte Luft oder in anderer Weise erzeugen, je nach der Stellung der Speichen und nötigenfalls dazu auch die Speichen des Rades der Hochdruckmaschine benutzen. Die Abdichtung des Laufrades gegen das Gehäuse erfolgt auf beiden Seiten durch einen ^ich unmittelbar an die Wangen und Vorsprünge anschließenden breiten Ring mit Nuten für Kolbenringe (hier drei) mit rechteckigem oderHousing a ¹ and impeller δ ¹ together with eight abutment slides d form system 1, the push-up machine, housing a ² and impeller δ ² together with their eight abutment slides system 2, the medium-pressure machine, housing a ³ and impeller δ ³ together with their eight abutment slides System 3, the low pressure machine. Each impeller has three projections c acting as pistons. The abutment slides are spring-loaded, but can also be controlled as in known machines; They are hollow and thus allow air cooling, which can be increased if necessary by closing the guides of the slide with two flap valves so that the abutment slide sucks in cooling air like a pump when it goes down through one valve and expels it through the other when it goes up. The cooling of the impellers and housing is done by an air stream, penetrating between the impeller spokes of the high-pressure machine and laterally between the housing parts, sweeps through the machine and in this through the inclined flat spokes of the low-pressure machine (Fig. Ι and 5), which in the manner of a Suction fan act, is generated. This air flow can also be generated by compressed air or in some other way, depending on the position of the spokes and, if necessary, also use the spokes of the wheel of the high-pressure machine. The impeller is sealed against the housing on both sides by a wide ring directly adjoining the cheeks and projections with grooves for piston rings (here three) with rectangular or

Claims

U-shaped cross-section. These piston rings, which are visible in cross section in FIG., Rotate with the impeller. Each impeller has side cheeks running from one protrusion to the other, of which those on the exhaust side, however, have triangular cutouts f directly on each protrusion - on the side facing away from the nozzles - which represent exhaust openings and lead into a channel i from the shape of a hollow prism (see. 'Fig. 3 \ and 6) open, which leads the burned gases from one impeller to the other. Since three such hollow prisms, the interior of which could also be tubular, are present between two running wheels with three projections, all wheels are thereby united into a rigid whole, so that 'every shaft inside is superfluous if it is not used as with this one Machine for supplying the. Wants to use propellants from the exhaust side. These channels are designed so that part of the flow energy can act by reaction. The machine works in such a way that compressed air produced by a fan coupled to the engine blows gasoline or another propellant into chamber e in a finely atomized form and is ignited here electrically or through glow tubes. The high combustion temperature causes the compressed air increases to five to six times the volume and also does five to six times the work that was needed to produce it.From the chamber, the gases enter the hollow spokes, which, like chamber e, are lined with fireproof thermal insulation the nozzles of the projections c of the impeller of the high-pressure machine and through the nozzles into the continuously forming explosion chambers, the side, back and bottom walls of which form the impeller, the top and front walls of which form the housing and abutment slide. that the exhaust behind the abutment slide in question can only take place when the next one ste abutment slide has descended and has formed a new chamber with the relevant projection and its cheeks. The machine does not need any valves for operation. The gases that have escaped from the high-pressure machine pass all the impellers, performing work, as shown in FIG. 6, and finally collect in the exhaust chamber g of FIG. 1, from where they reach the open air. The number of voltage levels can of course be increased or decreased and the high-pressure machine can be replaced by a known explosion motor of the appropriate construction (also known as an action motor). If the machine is provided with a heat protection jacket, it is also ideally suited for operation with steam or compressed air. Pa ten τ-An Proverbs:

1. Compound internal combustion engine with impellers (rotating pistons) and thrust slides, characterized in that the burned gases flow over from impeller to impeller in special channels Perform work.

2. composite internal combustion engine according to claim i, characterized in that the Impellers are designed and combined into a hollow body, and that the Air penetrating laterally between the individual housings and the impellers on all sides Causes cooling.
