Abstract
(DE)
Bei einer Stirlingmaschine umfassend einen Kompressionskolben mit einem zugeordneten Kompressionszylinderraum (3), einem Expansionskolben mit einem zugeordneten Expansionszylinderraum (2) und wenigstens eine Verbindungsleitung zwischen Kompressionszylinderraum (3) und Expansionszylinderraum (2), wobei in der Verbindungsleitung (4) eine Erhitzer-Regenerator-Kühler-Anordnung (5) vorgesehen ist, sowie eine Vorrichtung zur Koordinierung der relativen Bewegung von Kompressionskolben und Expansionskolben, ist zur Erzielung einer Phasenverschiebung zwischen Kompression und Verdrängung von im wesentlichen 90° bei relativ hohen und höchsten Drehzahlen vorgesehen, dass im Expansionszylinderraum (2) und im Kompressionszylinderraum (3) Totvolumina vorgesehen sind, dass diese Totvolumina (1) zusammen mit den Hubräumen als Gasfedern dienen, und dass die Grössen der beiden Totvolumina (1) die Phasenlage zwischen Kompression und Verdrängung bestimmen.
(EN)
The invention concerns a Stirling engine comprising a compression piston with an associated compression cylinder chamber (3), an expansion piston with an associated expansion cylinder chamber (2) and at least one connection line between the compression cylinder chamber (3) and the expansion cylinder chamber (2). Provided in the connection line (4) is a heater-regenerator-cooler arrangement (5). A device for co-ordinating the relative movement of the compression and expansion pistons is also provided. In order to bring about a phase shift of substantially 90° between compression and displacement at relatively high and maximum engine speeds, the expansion cylinder chamber (2) and compression cylinder chamber (3) have dead volumes (1) which, together with the total displacement volumes, act as pneumatic springs. The sizes of the two dead volumes (1) determine the phase relation between compression and displacement.
(FR)
L'invention concerne un moteur Stirling comprenant un piston de compression avec un cylindre de compression (3) associé, un piston de détente avec un cylindre de détente (2) associé, et au moins une conduite de raccordement entre le cylindre de compression (3) et le cylindre de détente (2). Un dispositif réchauffeur-régénérateur-refroidisseur (5) est monté dans la conduite de raccordement (4). Un dispositif coordonne le mouvement relatif du piston de compression et du piston de détente. Afin d'obtenir un décalage de phase entre la compression et le déplacement de pratiquement 90°, à des vitesses de rotation relativement élevées et maximales, le cylindre de détente (2) et le cylindre de compression (2) présentent des volumes morts (1) qui servent de ressorts à gaz avec les cylindrées. Les dimensions des deux volumes morts (1) déterminent la relation des phases entre compression et déplacement.
