Abstract
Description
Beschreibung eines hermetisch geschlossenen Heizkreissy stemes für den unteren und mittleren Temperaturbereich, geeignet zum berührungslosen Antrieb von Drehkolbenmotoren.Description of a hermetically sealed heating circuit stemes for the lower and middle temperature range, suitable for contactless drive of rotary lobe motors.
Die bekannten Drehkolbenmotore scheiterten bisher im allge meinen an der Problematik der Abdichtung und der Schmierung. Nachfolgend ist ein Heizkreissystem beschrieben, welches mit zwei verschiedenen Flüssigkomponenten arbeitet. Aus Sicherheits- und Funktionsgründen ist das Motor- und Rohr system nach außenhin dicht verschlossen. Die Wärmezufuhr wirkt von außenher auf den Verdampfer.The known rotary piston engines have so far generally failed mean the problem of sealing and lubrication. A heating circuit system is described below, which works with two different liquid components. Out The engine and pipe are safety and functional reasons system tightly sealed to the outside. The heat supply acts on the evaporator from the outside.
Die wesentlichen Bestandteile dieses Kreissystems bestehen aus Verdampfer, Drehkolbenmotor, Kondensation und Speise pumpe. Diese Bauelemente und verschiedene Armaturen sind mittels Druckrohrleitungen miteinander fest bzw. dicht verbunden. Als Kraftkomponente ist im Inneren des Systems Flüssiggas eingefüllt. Dieses Flüssiggas (Propangas, Benzin, Freon etc.) wird im Verdampfer in Druck umgesetzt und dem Drehkolbenmotor als Antrieb zugeführt, wo die Drehbewegung erfolgt. Den Dampffüllungsgrad im Arbeitsraum bestimmt ein Drehschieber oder ein Ventil, die nachfolgende Expansion kann dann infolge des langen kreisförmigen Arbeitshubes bis nahe des Kondensationspunktes des Flüssiggases erfolgen. In der Kondensation wird das entspannte Gas, natürlich unter Berücksichtigung des zur Flüssiggastemperatur gehörenden Druckes, gesammelt. Dem Flüssiggas wird eine Dicht- und Schmierkomponente in Form eines temperaturbeständigen Öles beigemengt. Beide Komponenten müssen mischbar sein, dürfen also keine chem. Verbindung bei Temperaturerhöhung eingehen. Bekannte Mischungen sind z. B. Benzin und Additive, welche bei Verbrennungsmotoren im kleinen Mischungsverhältnis ver wendet werden.The essential components of this circular system exist consisting of evaporator, rotary lobe motor, condensation and feed pump. These components and various fittings are tight or tight with each other by means of pressure pipelines connected. As a force component is inside the system LPG filled. This liquid gas (propane gas, gasoline, Freon etc.) is converted into pressure in the evaporator and the Rotary piston motor supplied as a drive where the rotary motion he follows. The degree of steam filling in the work area determines Rotary vane or a valve, the subsequent expansion can then due to the long circular working stroke to close to the condensation point of the liquid gas. In the condensation, the relaxed gas is, of course, below Consideration of the liquid gas temperature Pressure, collected. The LPG becomes a sealing and Lubrication component in the form of a temperature-resistant oil added. Both components must be miscible so no chem. Establish a connection when the temperature rises. Known mixtures are e.g. B. gasoline and additives, which for internal combustion engines in a small mixture ratio be applied.
Im Gegensatz zum Kolbenmotor, bei welchem die metallische Abdichtung mittels elastischer Kolbenringe gut möglich ist, gibt es beim Kreiskolbenmotor erhebliche Probleme. Anders bei dem hier beschriebenen System: Von der Kondensation aus wird das Flüssiggas-Additivgemisch mittels Speisepumpe dem Verdampfer zugeleitet. Dort trennen sich unter Temperatur einwirkung beide Flüssigkeiten, das Additiv bleibt flüssig und wird von einem Sammler bzw. Sumpf aus abgeführt und über Dosierventil den Lagerstellen der Rotoren des Dreh kolbenmotors zugeleitet. Durch separate Kanäle gelangt es in den schmalen Zwischenraum von Rotor und Gehäuse und infolge der Fliehkraft dort in den Arbeitsraum. Allseits sorgt es dann im ständig strömenden Fluß für Dichtung und Schmierung. Im Arbeitsraum selbst gleitet die schmale Dichtfläche des Zahnkolbens wie eine Kufe über die mit Additiv benetzte Gehäu sewand und dichtet perfekt ab.In contrast to the piston engine, in which the metallic Sealing with elastic piston rings is possible, there are considerable problems with the rotary piston engine. Different in the system described here: from the condensation the liquefied gas additive mixture by means of a feed pump Evaporator fed. There separate under temperature both liquids act, the additive remains liquid and is discharged from a collector or swamp and via dosing valve the bearings of the rotors of the rotary piston engine fed. It comes in through separate channels the narrow space between the rotor and housing and as a result the centrifugal force there into the work area. Everyone cares then in the constantly flowing river for sealing and lubrication. The narrow sealing surface of the Toothed piston like a skid over the housing wetted with additive sewand and seals perfectly.
Der vorgesehene Drehkolbenmotor gehört nicht zur Erfindung, er ist bereits seit längerer Zeit bekannt.The intended rotary piston engine is not part of the invention, it has been known for a long time.
Zwei kreisrunde Rotoren, welche sich um ihre Achse drehen und sich mit den Zylinderflächen berühren, sind auf ihrem Umfang mit je einem Zahn und einer Zahnlücke versehen. Bei Rotation greift der Zahn des einen Rotors in die Zahnlücke des anderen Rotors. Das Gehäuse, in welchem sich das Ganze bewegt, gleicht dem Innenraum einer Zahnradpumpe. Der Gleich lauf wird erzielt durch ein separates Zahnradpaar, welches sich außerhalb in einen geschlossenen Nebengehäuse befindet. Die wirksame Kolbenfläche im Arbeitsraum beträgt:Two circular rotors that rotate around their axis and touch with the cylinder surfaces are on theirs Provide circumference with one tooth and one tooth gap. At Rotation engages the tooth of one rotor in the tooth gap of the other rotor. The housing in which the whole is moved, resembles the interior of a gear pump. The same run is achieved by a separate pair of gears, which is outside in a closed secondary housing. The effective piston area in the work area is:
F = 2 · Kopfhöhe · Zahnbreite. F = 2 · head height · tooth width.
Da die Energieträger innerhalb des Kreissystems vorwiegend brennbare Flüssigkeiten sind, kann aus Sicherheitsgründen keine drehende Welle nach außen geführt werden. Es ist des halb zweckmäßig, innerhalb des Systems einen elektr. Magnet anker mit den Rotoren zu koppeln und durch einen dünnen anti magnetischen Zylinder in einen außerhalb befindlichen Stator Wechselstrom zu indizieren. Gehäuseinnenräume, welche nicht zum Hochdruckteil gehören (Gleichlaufzahnräder u. Magnet anker), sind mit dem Niederdruckgasraum der Kondensation verbunden.Because the energy sources within the circular system predominantly are flammable liquids for safety reasons no rotating shaft can be guided outside. It is the half expedient, an electrical within the system. Magnet to couple the anchor with the rotors and with a thin anti magnetic cylinder in an external stator Index alternating current. Housing interiors, which are not belong to the high pressure part (synchronous gears and magnet anchor), are with the low-pressure gas space of the condensation connected.
Infolge des niedrigen Siedepunktes der Flüssiggase ist es möglich, viele zur Verfügung stehender Energien im Nieder temperaturbereich, mit dieser Erfindung wirkungsvoll elektr. Strom zu erzeugen.As a result of the low boiling point of liquid gases, it is possible, many available energies in the low temperature range, with this invention effectively electr. To generate electricity.
