Abstract
Description
Bei der Vorrichtung handelt es sich um eine Pumpe, die Wärme für den Antrieb von Schiffen und Hydromotoren nutzbar macht, wie es bisher überwiegend mit Kolben motoren mit innerer Verbrennung erreicht wird. Die herkömmliche Methode verursacht eine hohe Schadstoff- und Geräuschbelastung der Umwelt und deren Verminderung ist sehr aufwendig und teuer. Auch der Kurbel- und Ventiltrieb ist sehr aufwendig und erschütternd. Zudem ist das Drehmoment der Kolbenmotoren drehzahlabhängig, so daß es häufig durch ein Getriebe an die Erfordernisse angepaßt werden muß. Hier sollte eine deutliche Verbesserung erreicht werden.The device is a pump that uses heat to drive Ships and hydraulic motors can be used, as was previously the case with pistons engines with internal combustion is achieved. The conventional method causes is a high pollution and noise pollution of the environment and their reduction very complex and expensive. The crank and valve train is very complex and shattering. In addition, the torque of the piston motors is speed-dependent, so that it often has to be adapted to the requirements by a gear. Here should a significant improvement can be achieved.
Kernstück (Bild 1) des Verfahrens ist ein zylindrischer Rotor (1) mit axial angeordneten zylindrischen Zellen (8), in denen sich Kolben (3) zwischen den Enden frei bewegen kön nen. Der Rotor ist umgeben von einem Gehäuse (2), das an seinen Enden einerseits Öffnungen oder Anschlüsse als Dampfein- (4) bzw. -Austritt (5) und andererseits Vor laufanschluß (6) und Rücklaufanschluß (7) für einen Hydromotor aufweist. Die An schlüsse sind so angeordnet, daß jeweils Dampfeintritt (4) und Vorlaufanschluß (6) als auch Dampfaustritt (5) und Rücklauf (7) durch höchstens die Hälfte der Rotorzellen, beispielsweise eine Zelle, zumindest zeitweise miteinander verbunden sind.The heart of the process ( Figure 1) is a cylindrical rotor ( 1 ) with axially arranged cylindrical cells ( 8 ) in which pistons ( 3 ) can move freely between the ends. The rotor is surrounded by a housing ( 2 ), which has at one end openings or connections as steam inlet ( 4 ) or outlet ( 5 ) and on the other hand before run connection ( 6 ) and return connection ( 7 ) for a hydraulic motor. The connections are arranged so that each steam inlet ( 4 ) and flow connection ( 6 ) as well as steam outlet ( 5 ) and return ( 7 ) by at most half of the rotor cells, for example a cell, are at least temporarily connected to each other.
Strömt nun Dampf aus dem Verdampfer unter Druck durch den Eintritt (4) in die Zelle (8) so wird der Kolben (3) an das andere Ende des Rotors (1) geschoben. Die Hydraulik flüssigkeit wird dadurch aus der Vorlauföffnung (6) in die Leitung zu einem Hydromotor und zurück in die Rücklauföffnung (7) der Pumpe gedrückt und verdrängt dort den Dampf aus der Zelle des Rotors, die sich jetzt aufgrund seiner Drehung zwischen dem Rücklaufanschluß (7) und dem Dampfaustritt (5) befindet. Der Dampf verläßt die Pumpe und strömt in einen Kondensator, um dann als Flüssigkeit wieder in den Verdampfer eingespritzt zu werden.If steam now flows from the evaporator under pressure through the inlet ( 4 ) into the cell ( 8 ), the piston ( 3 ) is pushed to the other end of the rotor ( 1 ). The hydraulic fluid is thereby pressed from the feed opening ( 6 ) into the line to a hydraulic motor and back into the return opening ( 7 ) of the pump, where it displaces the steam from the rotor cell, which is now due to its rotation between the return connection ( 7 ) and the steam outlet ( 5 ). The steam leaves the pump and flows into a condenser, in order to be then injected as a liquid back into the evaporator.
Ersetzt man den Kondensator und den Verdampfer durch einen Kühler, einen Regenerator einen Verdichter und einen Erhitzer, so arbeitet die Vorrichtung als Heißgasmotor.If you replace the condenser and the evaporator with a cooler, one Regenerator a compressor and a heater, so the device works as Hot gas engine.
Anstelle des Hydraulikkreises kann auch Wasser direkt aus einem Gewässer entnommen und die Vorrichtung als Jetantrieb für Schiffe genutzt werden. Dazu bietet es sich an, die Einbaulage der Pumpe so zu wählen, daß ein Teil der Zellen sich durch die Fahrt des Schiffes zumindest teilweise mit Wasser füllen und bei Stillstand nicht leerlaufen kann. Instead of the hydraulic circuit, water can also be taken directly from a body of water removed and the device can be used as a jet propulsion system for ships. To do this It is important to choose the installation position of the pump so that a part of the cells can penetrate fill the ship's voyage at least partially with water and not when it is at a standstill can run empty.
Das Verfahren kommt mit einfachen Baugruppen aus, was eine erhebliche Gewichts- und Kostenersparnis bedeutet. Die Äußere Beheizung läßt alle denkbaren Wärme quellen zu, bei Verbrennung mit geringster Abgasbelastung. Sowohl der Betrieb als Dampfkraftmaschine als auch als Antrieb nach dem Stirlingprinzip kann realisiert werden. Schon im Stillstand wird der Höchstdruck erreicht, so daß ein Drehmoment wandel in vielen Fällen entfallen kann.The process works with simple assemblies, which means a considerable weight and cost savings means. The outside heating leaves all possible warmth swell when burning with the lowest exhaust gas pollution. Both the operation as Steam engine as well as a drive according to the Stirling principle can be realized become. The maximum pressure is reached even at a standstill, so that a torque change can be omitted in many cases.
Durch eine Wärmerückgewinnung kann ein hoher Wirkungsgrad erreicht werden. Es ist eine Heizung vorhanden, die auch für die Fahrgastraumbeheizung genutzt werden kann. Die Geräuschentwicklung ist niedrig, da nur gleichmäßige Strömungen und Drücke mit geringer Welligkeit auftreten. Der Hydraulische Antrieb kann mit wenig Zusatzaufwand als Bremse, Differential und Drehmomentwandler ausgebildet werden.A high level of efficiency can be achieved by heat recovery. It is there is a heater that can also be used to heat the passenger compartment can. The noise level is low because there are only even currents and Low ripple pressures occur. The hydraulic drive can do with little Additional effort to be trained as a brake, differential and torque converter.
