Abstract

Bei einer Wärmekraftmaschine, insbesondere einem Stirling-Motor, umfassend einen Verdrängerkolben und ei­ nen Arbeitskolben, welche miteinander gekoppelt in einem nach außen dicht abgeschlossenen Gehäuse linear geführt schwingungsfähig angeordnet sind, wobei der Gasraum zwischen Verdränger- und Arbeitskolben mit dem Gasraum zwischen Verdrängerkolben und Gehäuse über eine Erhit­ zer-, Kühler-, Regenerator-Anordnung verbunden ist, und wobei eine externe Wärmequelle anschließbar ist, ist zur­ Ermöglichung einer problemlosen Auskopplung mechani­ scher Energie durch das geschlossene Gehäuse nach au­ ßen vorgesehen, daß wenigstens mit dem Arbeitskolben (2) eine magnetische oder magnetisierbare, innerhalb des Ge­ häuses (1) angeordnete Kopplungs-Einrichtung (9, 15) ver­ bunden ist, und daß eine korrespondierende magnetische oder magnetisierbare Kopplungs-Einrichtung (8, 18) außer­ halb des Gehäuses (1) parallel zum Kolbenweg beweglich gelagert ist. In a heat engine, especially one Stirling engine, comprising a displacement piston and egg NEN piston, which are coupled together in one linearly sealed housing sealed to the outside are arranged to vibrate, the gas space between the displacer and the working piston with the gas space between displacement piston and housing via a heater zer, cooler, regenerator arrangement is connected, and whereby an external heat source can be connected Enable problem-free coupling mechani energy through the closed housing to the outside ß provided that at least with the working piston (2) a magnetic or magnetizable, within the Ge housing (1) arranged coupling device (9, 15) ver is bound, and that a corresponding magnetic or magnetizable coupling device (8, 18) except half of the housing (1) movable parallel to the piston path is stored.

Um insbesondere das Schwingungsverhalten von Ar­ beitskolben und Verdrängerkolben in jeder Betriebsphase kontrollieren zu können, ist weiterhin vorgesehen, daß eine Vorrichtung zur Vorgabe der Phasenlage zwischen Arbeits­ kolben (2) und Verdrängerkolben (4) durch ein magnetisch angekoppeltes mechanisches Getriebe, insbesondere ein Kurbelwellengetriebe gebildet wird. Insbesondere ist vor­ gesehen, daß von der translatorischen Bewegung der Kol­ ben eine auf diese übertragene Drehbewegung abgegriffen wird, wobei die hierzu dienenden Übertragungs-Einrichtun­ gen gleichzeitig auch die Phasenlage der Kolben festlegen können. Die Drehbewegung der Kolben kann mittels der erfindungsgemäßen Kopplungs-Einrichtungen magnetisch ausgekoppelt und direkt auf eine Abtriebswelle übertragen werden. In particular, the vibration behavior of Ar working pistons and displacement pistons in every operating phase to be able to control, it is also provided that a Device for specifying the phase position between work piston (2) and displacement piston (4) by a magnetic coupled mechanical transmission, in particular a Crankshaft gear is formed. In particular is before seen that from the translational movement of the Kol ben tapped a rotary motion transferred to this the transmission equipment used for this purpose also determine the phase position of the pistons can. The rotation of the pistons can be controlled by means of the Coupling devices according to the invention magnetic uncoupled and transferred directly to an output shaft will.
