Derartige Vorrichtungen, die beispielsweise als Stirlingmotoren ausgebildet sein können, sind Arbeitsmaschinen, die häufig zur Bereitstellung von elektrischer Energie dienen. Große Vorteile dieser Maschinen sind in erster Linie ein relativ hoher Wirkungsgrad des theoretischen Kreisprozesses und die vielfältigen Gestaltungsmöglichkeiten bei der Zufuhr von thermischer Energie. Bei Stirlingmaschinen kann die Wärmezufuhr sowohl durch Verbrennung fester, flüssiger oder gasförmiger Brennstoffe erfolgen als auch mittels konzentrierter Solarstrahlung. Damit bietet dieses Antriebsprinzip vielfältige Einsatzmöglichkeiten und kann bei entsprechender Brennstoffauswahl (beispielsweise Biomasse), verbunden mit einem hohen Wirkungsgrad, auch wesentlich zur Reduzierung des klimaschädlichen Treibhausgases CO2 bei der Erzeugung und Umwandlung von Energie beitragen.Such devices, which may be designed, for example, as Stirling engines, are working machines which often serve to provide electrical energy. The great advantages of these machines are first and foremost a relatively high efficiency of the theoretical cycle and the many design options for the supply of thermal energy. In Stirling engines, the heat can be supplied both by burning solid, liquid or gaseous fuels as well as by means of concentrated solar radiation.

Hinsichtlich ihrer Ausführungsform können Stirlingmotoren in einen sog. Alpha-Typ, einen Beta-Typ und einen Gamma-Typ eingeteilt werden. Während der Alpha-Typ zweizylindrig ausgebildet ist, beinhaltet der Beta-Typ lediglich einen Zylinder mit einer Kaltzone und einer Heißzone. Eine Mischform aus Alpha- und Beta-Typ bildet der sog. Gamma-Typ, der einen Verdrängerzylinder mit einer heißen und einer kalten Zone aufweist und zudem einen, hinsichtlich seines Volumens zumeist kleiner ausgebildeten Arbeitszylinder.With regard to their embodiment, Stirling engines can be classified into a so-called alpha type, a beta type and a gamma type. While the alpha type is two-cylinder, the beta type includes only one cylinder with a cold zone and a hot zone. A mixed form of alpha and beta type forms the so-called.

Weiter soll die Vorrichtung hinsichtlich ihrer Bauform einfach ausgebildet sein und kostengünstig realisierbar sein.An object of the present invention is to provide an improved apparatus for reducing or increasing a volume of gas having the highest possible efficiency. Next, the device should be simple in design and be inexpensive to implement.
Die obige Aufgabe wird durch eine Vorrichtung gelöst, welche die Merkmale des Anspruchs 1 umfasst. Merkmale vorteilhafter Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The above object is achieved by an apparatus comprising the features of
Die erfindungsgemäße Vorrichtung kann insbesondere als Stirlingmotor ausgebildet sein und umfasst einen ersten Zylinder mit einem ersten Kolben und einen zweiten Zylinder mit einem zweiten Kolben. Der Stirlingmotor der vorliegenden Erfindung kann in der sog. Alpha-Konfiguration ausgebildet sein. Vorzugsweise jedoch ist der Stirlingmotor in der Gamma-Konfiguration ausgebildet. Die beiden kommunizierenden Zylinder der vorliegenden Erfindung können hinsichtlich ihres Volumens unterschiedlich ausgebildet sein. Beispielsweise kann der erste Zylinder ein größeres Volumen aufweisen als der zweite Zylinder. Besonders in der Gamma-Konfiguration kann es von Vorteil sein, das Volumen des ersten Zylinders größer zu wählen als das Volumen des zweiten Zylinders, wenn der erste Zylinder als Verdrängerzylinder und der zweite Zylinder als Arbeitszylinder ausgebildet ist.The device according to the invention can in particular be designed as a Stirling engine and comprises a first cylinder with a first piston and a second cylinder with a second piston. The stirling engine of the present invention may be formed in the so-called alpha configuration. Preferably, however, the Stirling engine is configured in the gamma configuration. The two communicating cylinders of the present invention may be different in volume. For example, the first cylinder may have a larger volume than the second cylinder. Especially in the gamma configuration, it may be advantageous to choose the volume of the first cylinder larger than the volume of the second cylinder, when the first cylinder is designed as a displacement cylinder and the second cylinder as a working cylinder.
Weiter können der erste und/oder der zweite Kolben als Regenerator ausgebildet sein. Dies kann dadurch erfolgen, indem zur Ausgestaltung des jeweiligen Kolbens Materialien mit hoher Wärmekapazität und geringer Wärmeausdehnung gewählt werden. Beispielsweise kommen zur Ausgestaltung des Kolbens Materialien auf Kupferbasis in Frage. Zudem sind beispielsweise eine Vielzahl von Legierungen geeignet, die dem Fachmann bekannt sind und daher nicht explizit erwähnt werden. Ist ein Kolben als Regenerator ausgebildet, so kann der Stirlingmotor mit höheren Temperaturen betrieben werden, woraus ein zusätzlicher verbesserter Wirkungsgrad resultiert.Further, the first and / or the second piston may be formed as a regenerator. This can be done by selecting materials with high heat capacity and low thermal expansion for the design of the respective piston. For example, come to design the piston materials based on copper in question. In addition, for example, a variety of alloys are suitable, which are known in the art and are therefore not explicitly mentioned. If a piston is designed as a regenerator, then the Stirling engine can be operated at higher temperatures, resulting in an additional improved efficiency results.
Der erste Zylinder und der zweite Zylinder weisen jeweils einen Durchbruch auf, der sich vom Innenraum des jeweiligen Zylinders durch die Zylinderaußenwand erstreckt. Der Verlauf des Durchbruchs durch die Zylinderaußenwand kann homogen oder inhomogen ausgebildet sein. Beispielsweise kann der Verlauf des jeweiligen Durchbruchs geradlinig und/oder kurvenartig ausgebildet sein. Der Durchmesser der Durchbrüche kann im Rahmen seines Verlaufes variieren. Der mittlere Durchmesser des Durchbruchs durch die erste Zylinderaußenwand und der mittlere Durchmesser des Durchbruchs durch die zweite Zylinderaußenwand können unterschiedlich ausgebildet sein.The first cylinder and the second cylinder each have an opening which extends from the interior of the respective cylinder through the cylinder outer wall. The course of the breakthrough through the cylinder outer wall may be formed homogeneous or inhomogeneous. For example, the course of the respective breakthrough be rectilinear and / or curved. The diameter of the apertures may vary within the course of its course. The mean diameter of the opening through the first cylinder outer wall and the average diameter of the opening through the second cylinder outer wall can be designed differently.
Mittels der Durchbrüche wird ein Strömungskanal zur direkten Weiterleitung eines Arbeitsmediums zwischen dem ersten und dem zweiten Zylinder ausgebildet. Dies kann dadurch erfolgen, indem der Durchbruch durch die erste Zylinderaußenwand am Durchbruch durch die zweite Zylinderaußenwand angeordnet wird. Auf einen zusätzlichen Strömungskanal, wie bei herkömmlichen Stirlingmotoren der Alpha- oder Gamma-Konfiguration vorhanden, kann hierdurch verzichtet werden. Die Weiterleitung des Arbeitsmediums erfolgt demnach direkt.By means of the apertures, a flow channel for the direct forwarding of a working medium between the first and the second cylinder is formed. This can be done by the breakthrough is arranged by the first cylinder outer wall at the opening through the second cylinder outer wall. On an additional flow channel, as in conventional Stirling engines of the alpha or gamma configuration present, this can be omitted. The forwarding of the working medium is therefore directly.
Auch können zwischen den beiden Durchbrüchen Dichtmittel vorhanden sein, um einen Austritt des Arbeitsmediums während der Weiterleitung zu unterbinden.Also, sealing means may be present between the two apertures to prevent leakage of the working medium during forwarding.
In einer bevorzugten Ausführungsform der vorliegenden Erfindung ist eine erste Achse A vorhanden, die durch den ersten Zylinder und parallel zur Zylinderaußenwand des ersten Zylinders verläuft und eine zweite Achse B, die durch den zweiten Zylinder und parallel zur Zylinderaußenwand des zweiten Zylinders verläuft, wobei die Achse A und die Achse B einen Winkel α einschließen für den gilt: α<90°. Durch diese Anordnung ergeben sich weitere Vorteile, wie beispielsweise die Möglichkeit den Phasenwinkel innerhalb bestimmter Grenzen zu variieren und so im Vergleich zu herkömmlichen Stirlingmotoren einen deutlich höheren Wirkungsgrad zu erreichen. In einer bevorzugten Ausführungsform der vorliegenden Erfindung beträgt der Winkel α zumindest annäherungsweise 35°.In a preferred embodiment of the present invention, there is a first axis A passing through the first cylinder and parallel to the cylinder outer wall of the first cylinder and a second axis B passing through the second cylinder and parallel to the cylinder outer wall of the second cylinder, the axis A and the axis B include an angle α for which applies: α <90 °. By this arrangement, there are further advantages, such as the ability to vary the phase angle within certain limits and thus to achieve a much higher efficiency compared to conventional Stirling engines. In a preferred embodiment of the present invention, the angle α is at least approximately 35 °.
Gemäß einer weiteren Ausführungsvariante der erfindungsgemäßen Vorrichtung bzw. des erfindungsgemäßen Stirlingmotors liegen die durch den ersten Zylinder verlaufende erste Achse und die durch den zweiten Zylinder verlaufende zweite Achse windschief zueinander, wodurch die beiden Zylinder näher zueinander rücken können, wodurch wiederum der zwischen den beiden Zylindern verlaufende Strömungskanal kürzer ausgebildet sein kann. Der Abstand der beiden Achsen kann vorzugsweise wenigstens 20% eines Durchmessers eines der beiden Zylinder entsprechen. Wäre der Abstand geringer, kann durch den Versatz kein nennenswerter Raumgewinn erzielt werden, der die Zylinder näher zueinander rücken lassen würde. Der Abstand kann sinnvoller Weise auch größer sein, ist jedoch zweckmäßigerweise immer im Zusammenhang mit der Neigung der beiden Achsen der Zylinder gegeneinander zu wählen, da nur bei einer abgestimmten Konstruktion der maximale Effekt aufgrund der bestmöglichen Kompaktheit der Bauform erzielt werden kann.According to a further embodiment of the invention Device or the Stirling engine according to the invention are extending through the first cylinder and the first axis extending through the second cylinder skew each other, whereby the two cylinders can move closer to each other, which in turn can be formed shorter between the two cylinders flow channel. The distance between the two axes may preferably correspond to at least 20% of a diameter of one of the two cylinders. If the distance were smaller, the offset can not achieve any appreciable space gain, which would bring the cylinders closer to each other. The distance may be meaningful way to be greater, but is expediently always in connection with the inclination of the two axes of the cylinder to choose against each other, since only with a coordinated design of the maximum effect due to the best possible compactness of the design can be achieved.

Dem ersten Bereich kann eine Heizvorrichtung zugeordnet sein. Weiter ist es möglich dem zweiten Bereich eine Kühlvorrichtung zuzuordnen. In dieser Ausführungsform kann der zweite Zylinder als Arbeitszylinder ausgebildet sein. Das Volumen des ersten Zylinders kann hierbei größer gewählt werden als das Volumen des zweiten Zylinders. Grundsätzlich gilt bei allen Konfigurationen, dass mit zunehmender Temperaturabsenkung mittels der Kühlvorrichtung der Wirkungsgrad des Stirlingmotors gesteigert werden kann.The first cylinder or the second cylinder may be designed as a displacement cylinder. The displacer cylinder may be divided into a first and a second area. The first area may be associated with a heater. It is also possible to assign a cooling device to the second area. In this embodiment, the second cylinder may be formed as a working cylinder. The volume of the first cylinder can be chosen to be greater than the volume of the second cylinder. Basically, in all configurations, the efficiency of the Stirling engine can be increased with increasing temperature reduction by means of the cooling device.
Weiter können Mittel am ersten und/oder am zweiten Bereich angeordnet sein, so dass der erste Bereich vom zweiten Bereich thermisch isoliert ist. Zur Isolation kommen beispielsweise Materialien mit geringer Wärmeleitfähigkeit in Betracht.Furthermore, means may be arranged on the first and / or on the second region, so that the first region is thermally insulated from the second region.
