B. einen am Motorge häuse 2 angeordneten Zahnkranz aufweisen, der mit an den Kolbenstangen 9 exzentrisch gelagerten Zahnrädern in Eingriff ist. Durch diese Zwangsführung werden die Keilkolben 7 bei Rotation der Rotorwelle 3 in Drehrichtung der Rotorwelle 3 in die aufeinanderfolgenden Arbeitskammern 5 eingeführt und wieder herausgeführt.The wedge-piston radial engine 1 shown schematically in FIG. 1 has a motor housing 2 , over the inner circumference 6 of which working chambers 5 with a generally wedge-shaped cross section are arranged in a successive row. For each working chamber 5 , a wedge piston 7 is also provided with a wedge-shaped cross section, the piston crown 8 on one side projects beyond the radial plane of the piston rod 9 connected to the wedge piston 7 . Each piston rod 9 is mounted radially displaceably in the rotor shaft 3 . For this purpose, a positive guide, not shown, is provided, which extends coaxially to the central axis 4 over the inner circumference of the motor housing 2 . This positive control can, for. B. have a sprocket arranged on Motorge 2 , which is in engagement with the piston rods 9 eccentrically mounted gears. Through this forced guidance, the wedge pistons are inserted into the successive working chambers 5 during rotation of the rotor shaft 3 in the direction of rotation of the rotor shaft 3 and 7 out again.
Die Übergänge 10 zwischen den Arbeitskammern 5, die Kolben spitzen 11 und die Arbeitskammerböden 12 sind abgerundet ausgebildet (Fig. 1 und Fig. 2). Der Öffnungswinkel α der Arbeitskammern 5 ist kleiner als der Keilwinkel β der Keilkolben 7. Im kolbeneintrittsseitigen Bereich 14 der je weils einen Arbeitskammerwand 13 ist eine Dichtleiste 15 angeordnet. Im Bereich der Kolbenspitze 11 ist in jedem Keil kolben 7 eine Dichtleiste 17 vorgesehen, die radial zu der Ebene der der Arbeitskammerwand 13 zugewandten Keilkolben fläche 24 verschieblich ist und an der Arbeitskammerwand 18 anliegt. An den Seitenflächen eines jeden Keilkolbens 7 ist jeweils ein sich von der Dichtleiste 17 bis zum Kolbenboden 8 über die Dichtleiste 15 hinaus erstreckender weiterer Dicht streifen 18 angeordnet.The transitions 10 between the working chambers 5 , the pistons 11 and the working chamber floors 12 are rounded ( Fig. 1 and Fig. 2). The opening angle α of the working chambers 5 is smaller than the wedge angle β of the wedge piston 7 . A sealing strip 15 is arranged in the piston inlet-side area 14 of each of the working chamber walls 13 . In the area of the plunger tip 11 is in each wedge piston 7 a sealing strip 17 is provided, the radially facing to the plane of the working chamber wall 13 wedge piston surface 24 is movable and rests against the work chamber wall 18th On the side surfaces of each wedge piston 7 , one from the sealing strip 17 to the piston crown 8 over the sealing strip 15 and extending further sealing strip 18 is arranged.
Im kolbeneintrittsseitigen Bereich 14 der einen Arbeitskam merwand 13 ist jeweils eine Einlaßöffnung 19 für ein gasför miges Fluid wie z. B. Dampf und im Bereich des Arbeitskammer bodens 12 eine Auslaßöffnung 20 für expandiertes und damit entspanntes gasförmiges Fluid vorgesehen. Jede Einlaßöffnung 19 ist mit einer Gaszuführleitung 21 verbunden, in der ein intermittierend ansteuerbares Ventil 22 angeordnet ist.In the piston inlet side area 14 of a working chamber 13 merwall each have an inlet opening 19 for a gas-shaped fluid such. B. steam and in the region of the working chamber floor 12, an outlet opening 20 is provided for expanded and thus relaxed gaseous fluid.

Es ist möglich, einen Keilkolben-Sternmotor aus mehreren Motorsegmenten zusammenzusetzen, die jeweils eine Anordnung von Keilkolben 7 und Arbeitskammern 5 aufweisen. Diese Keil kolben 7 der mehreren Motorsegmente sind vorteilhaft jeweils über ihre Kolbenstangen 9 mit der einen Rotorwelle 3 verbun den.It is possible to assemble a wedge piston radial engine from several engine segments, each of which has an arrangement of wedge pistons 7 and working chambers 5 . These wedge pistons 7 of the several motor segments are each connected via their piston rods 9 to the one rotor shaft 3 .
Die Anzahl der Keilkolben 7 je Motorsegment ist variabel. Es können acht bis sechsunddreißig oder mehr oder weniger vorge sehen werden.The number of wedge pistons 7 per motor segment is variable. Eight to thirty-six or more or less can be seen.
Sofern mehrere Motorsegmente in Reihe geschaltet werden, ist es zweckmäßig, diese um einige Grade des Rotorwinkels ver setzt zusammenzubauen. Hierdurch ist jeweils ein Motorsegment immer im Arbeitstakt, wodurch sich ein besserer Rundlauf des Keilkolben-Sternmotors 1 ergibt und auf eine Schwungmasse verzichtet werden kann.If several motor segments are connected in series, it is advisable to put them together by a few degrees of the rotor angle. As a result, one motor segment is always in the work cycle, which results in a better concentricity of the wedge piston star motor 1 and a flywheel can be dispensed with.
Bei dem Keilkolben-Sternmotor 1 kann hochgespannter Dampf von 10 bis 250 at bei ca. 650°C über die jeweilige Gaszuführ leitung 21 nach Öffnen des Ventils 22 in den Expansionsraum 23 der Arbeitskammer 5 geleitet werden. Jeder Expansionsraum 23 wird hierbei durch die einander zugewandten Flächen des Keilkolbens 7 und der einen Arbeitskammerwand 13 im Umfang der Dichtleisten 15, 17 sowie der Dichtstreifen 18 bestimmt. Die Dampfmenge wird hierbei über eine Dosiereinrichtung ge steuert. Der expandierende Dampf drückt den Keilkolben 7 in die Arbeitskammer 5 und wird dabei gleichzeitig durch die mechanische Zwangsführung in die Arbeitskammer 5 bewegt. In der Stellung des Keilkolbens 7 nach Fig. 5 ist der Dampf entspannt. Der Keilkolben 7 bewegt sich aus der betreffenden Arbeitskammer 5 heraus und in Drehrichtung der Rotorwelle 3 zur folgenden Arbeitskammer 5 weiter und wird dann in diese nächste Arbeitskammer 5 eingeführt.In the wedge-piston radial engine 1 , high-tension steam from 10 to 250 at at approx. 650 ° C. can be passed via the respective gas supply line 21 after opening the valve 22 into the expansion space 23 of the working chamber 5 . Each expansion space 23 is determined here by the mutually facing surfaces of the wedge piston 7 and the one working chamber wall 13 in the circumference of the sealing strips 15, 17 and the sealing strips 18 . The amount of steam is controlled ge via a metering device. The expanding vapor forces the wedge piston 7 in the working chamber 5 and is moved at the same time by the mechanical forced guidance in the working chamber. 5 In the position of the wedge piston 7 according to FIG. 5, the steam is released. The wedge piston 7 moves out of the working chamber 5 in question and further in the direction of rotation of the rotor shaft 3 to the following working chamber 5 and is then introduced into this next working chamber 5 .
Der Keilkolben-Sternmotor 1 ist für unterschiedliche Leistungsgrößen einsetzbar und eignet sich insbesondere für den stationären Betrieb wie auch für den mobilen Einsatz.The wedge piston radial engine 1 can be used for different output sizes and is particularly suitable for stationary operation as well as for mobile use.
Zur Erzeugung des Dampfes können biologische Brennstoffe verwendet werden. Hierdurch ist es möglich, einen geschlos senen Energiekreislauf mit der Natur zu erzielen. Der Keil kolben-Sternmotor ist auch aufgrund seiner spezifischen Bau weise als Vielstoffmotor einzusetzen.Biofuels can be used to generate the steam be used. This makes it possible to lock one to achieve its energy cycle with nature. The wedge Piston radial engine is also due to its specific construction wise to use as a multi-fuel engine.
