Abstract

The rotary pump for the Stirling engine has a bearing mounted rotor (3) moving in a housing split by thermal insulation (4) into heated and cooled sections. The gas is pumped alternately to the heated or cooled section of the engine. The walls of the engine are blackened for max. thermal transfer and have radial ribs. The alternating gas flow is ducted in one direction by directional valves. Hydrogen is a suitable gas. A membrane motor can be linked to the rotary section to eliminate a regenerator. ADVANTAGE - Simple construction; simple drive for pump.

Description

Stirlingmotoren wandeln Wärme- in Bewegungsenergie um. Ein Verdrängerkolben bewirkt das Verschieben des Arbeits­ gases wechselweise in eine heiße und eine kalte Kammer, wo­ durch eine Ausdehnung bzw. Zusammenziehung des Gases bewirkt wird. Der auftretende Druckunterschied betreibt den Arbeits­ kolben. Siehe: Stirlingmotor der Zukunft v. Manfred Künzel, Düsseldorf 1986.Stirling engines convert heat energy into kinetic energy. A displacement piston causes the work to be postponed gases alternately into a hot and a cold chamber where caused by expansion or contraction of the gas becomes. The pressure difference occurring does the work piston. See: Stirling engine of the future v. Manfred Künzel, Düsseldorf 1986.

Die Probleme die bisher hauptsächlich auftraten, waren die teuere Bauart, der Betriebsdruck (Dichtungsprobleme) der Wir­ kungsgrad (Totraum), die Phasenverschiebung von Verdränger und Arbeitskolben, eine schnelle Leistungsänderung und die starke Leistungsabnahme bei höheren Drehzahlen.The main problems so far have been expensive design, the operating pressure (sealing problems) of the We efficiency (dead space), the phase shift of the displacer and pistons, a quick change in performance and that strong decrease in performance at higher speeds.

Die mit der Erfindung erzielten Vorteile bestehen insbeson­ dere darin, daß die Bauweise einfacher und billiger als bis­ her ist und der Betriebsdruck wegen der guten Dichtigkeit hoch gewählt werden kann (bis über 300 bar) wodurch die Lei­ stung im Verhältnis zur Baugröße gut ist. Der Totraum ist klein und die Phasenverschiebung kann durch Computersteuerung im Verhältnis zur Drehzahl optimiert werden.The advantages achieved with the invention are in particular in that the construction is simpler and cheaper than up to ago and the operating pressure because of the good tightness can be selected high (up to over 300 bar) which means the lei is good in relation to the size. The dead space is small and the phase shift can be done by computer control be optimized in relation to the speed.

Der Innenraum des Läufergehäuses ist mit radialen Rippen aus­ gekleidet und hat eine rauhe geschwärzte Oberfläche. Dazu kann als Arbeitsgas Wasserstoff gewählt werden, wodurch höhere Drehzahlen möglich sind. Durch eine ventilgesteuerte Zuschal­ tung eines größeren Totraumes kann eine schnelle Leistungs­ änderung bewirkt werden, wie sie z. B. für Fahrzeuge nötig ist. Für Kraftwerke (z. B. Erdwärme) ist die Angleichsmöglichkeit an verschiedenste Hoch- und Tieftemperaturen, sowie die Com­ putersteuerung von Vorteil.The interior of the rotor housing is made with radial ribs dressed and has a rough blackened surface. To can be selected as the working gas hydrogen, making higher Speeds are possible. With a valve-controlled shutter a larger dead space can perform quickly Change can be brought about, such as. B. is necessary for vehicles. The adjustment option is available for power plants (e.g. geothermal energy) to various high and low temperatures, as well as the Com Computer control is an advantage.

Erläuterung der Erfindung nach Fig. 1Explanation of the invention according to FIG. 1

Gehäuseteil 1 wird durch eine beliebige Wärmequelle erhitzt. Gehäuseteil 2, der durch die Isolierdichtung 4 von Teil 1 ge­ trennt ist, wird gekühlt. Nun versetzt ein elektromagnetisches Wechselfeld in den Spulen 5 den kugelgelagerten Verdränger 3 mit dem Dauermagneten 6 in Drehbewegung. Das Gewicht 7 wuch­ tet den Läufer auf der ausgesparten Seite aus. Das elektro­ magnetische Wechselfeld wird elektronisch erzeugt.Housing part 1 is heated by any heat source. Housing part 2 , which is separated by the insulating seal 4 from part 1 , is cooled. Now an alternating electromagnetic field in the coils 5 rotates the ball-bearing displacer 3 with the permanent magnet 6 . Weight 7 balances the runner on the recessed side. The alternating electromagnetic field is generated electronically.

Die aus Fig. 1 ersichtliche Form des Verdrängers bewirkt nun ein wechselweises Verschieben der Hauptmasse des Arbeitsga­ ses in den heißen, oder den kalten Bereich der Läuferkammer. Man erhält nun eine Druckschwingung, die durch die Anschluß­ öffnung 8 in einen geeigneten Motor übertragen wird.The apparent from Fig. 1 shape of the displacer now causes an alternate displacement of the main mass of the Arbeitsga ses in the hot, or the cold area of the rotor chamber. A pressure oscillation is now obtained, which is transmitted through the connection opening 8 into a suitable motor.

Fig. 2 stellt die vereinfachte Darstellung eines Membran­ motors dar, dem mit einem variablen Absperrventil ein Druck­ raum (Totraum) zur schnellen Leistungsänderung zugeschaltet werden kann. Es können auch Kolbenmotoren verwendet werden. Fig. 2 shows the simplified representation of a diaphragm motor, which can be switched on with a variable shut-off valve, a pressure chamber (dead space) for rapid power change. Piston motors can also be used.

Fig. 3 zeigt einen verstellbaren, pneumatischen Flügelzellen­ motor und eine Ventilanordnung zur Umwandlung der Gasschwin­ gungen des Druckerzeugers in eine gleichströmende Bewegung. Fig. 3 shows an adjustable, pneumatic vane motor and a valve arrangement for converting the gas vibrations of the pressure generator into a co-current movement.

Fig. 4 ist die schematische Darstellung des Zusammenwirkens von Verdränger, Motor und Computer. Der Verdränger wird hier­ bei elektromagnetisch angetrieben, geregelt von einem ent­ sprechendem Computer, der die effektivste Phasenverschiebung, nach Drehwinkel des Motors und des Verdrängers zur Leistungs­ optimierung und Leistungssteuerung berechnet. Fig. 4 is a schematic representation of the interaction of the displacer, motor and computer. The displacer here is electromagnetically driven, controlled by a corresponding computer that calculates the most effective phase shift, based on the angle of rotation of the motor and the displacer for performance optimization and power control.
