Abstract
Technische Aufgabe und Zielsetzung Bei einer bekannten Rotationskolbenmaschine (s. DE 10 256 722 A1) wird die Fluidführung durch das Innere eines Dichtrotors geleitet. Auf diese Weise kann ein Fluid durch ein variierendes Arbeitsvolumen nur pulsierend aus diesem Arbeitsvolumen (2) in den Dichtrotor (4) geschoben werden, was den Einsatz derartiger Maschinen aufgrund der äußerst geringen Kompressibilität von Flüssigkeiten als Flüssigpumpen unmöglich macht. Des Weiteren ist es bei bekannter Bauweise nur mit erheblichem Aufwand möglich, derartige Maschinen mit variablem Kompressionsdruck zu betreiben. Die hier dargestellte Erfindung ermöglicht den Einsatz von Rotationskolbenmaschinen zur Flüssigkeitsförderung und als Kompressor mit variablem Kompressionsdruck. Lösung des Problems Durch die hier dargestellte Erfindung wird die Anwendung von Rotationskolbenmaschinen zur Flüssigkeitsförderung und zum Einsatz als Kompressor mit variablem Kompressionsdruck mit einer neuartigen Fluidführung ermöglicht. Die Fluidführung wird durch einen speziellen Strömungskanal im Inneren des Arbeitsrotors, ohne den Weg über den Dichtrotor, bewerkstelligt. Durch die hier beschriebene Erfindung wird eine flüssige Strömung nahezu laminar durch die Maschine geleitet, was einen äußerst guten Wirkungsgrad zur Folge hat. Anwendungsgebiet Eine nach dieser Erfindung gestaltete Rotationskolbenmaschine kann als Flüssigkeitspumpe zur Förderung von Flüssigkeiten in nahezu allen Bereichen eingesetzt werden. Beim Einsatz der Rotationskolbenmaschine als Kompressor mit variablem Kompressionsdruck kann diese in allen Bereichen der technischen Chemie, der Lufterzeugung, der Erdölindustrie und als Ladeluftkompressor für Verbrennungsmaschinen eingesetzt werden.Technical Problem and Objective In a known rotary piston machine (see DE 10 256 722 A1), the fluid guide is passed through the interior of a sealing rotor. In this way, a fluid can be pushed by a varying working volume only pulsating from this working volume (2) in the sealing rotor (4), which makes the use of such machines impossible due to the extremely low compressibility of liquids as liquid pumps. Furthermore, it is possible only with considerable effort to operate such machines with variable compression pressure in known construction. The invention presented here allows the use of rotary piston machines for fluid delivery and as a compressor with variable compression pressure. Solution to the Problem The present invention enables the use of rotary-piston machines for fluid delivery and for use as a variable-compression-pressure compressor with a novel fluid guide. The fluid guide is accomplished by a special flow channel in the interior of the working rotor, without the way through the sealing rotor. By the invention described herein, a liquid flow is almost laminar passed through the machine, which has an extremely good efficiency result. Field of application A rotary piston machine designed according to this invention can be used as a liquid pump for conveying liquids in almost all areas. When using the rotary piston engine as a compressor with variable compression pressure, this can be used in all areas of technical chemistry, air production, the oil industry and as a charge air compressor for internal combustion engines.
