Title
(EN) COMPOUND ROTARY INTERNAL COMBUSTION ENGINE
(FR) MOTEUR A COMBUSTION INTERNE ROTATIF COMPOSITE
Abstract
(EN)
An internal combustion engine of the rotary type in which a pair of axially spaced combustion chambers (24a, 26a) are provided and a common ratchet or control mechanism (16) is positioned between the spaced combustion chambers. A pair of vanes (40, 42, 44, 46) are mounted in each combustion chamber with the vanes mounted on concentric shafts (36, 38) and free to rotate relative to each other. The ratchet mechanism positioned between the combustion chambers functions to resist counterclockwise movement of the vanes in one combustion chamber while allowing free clockwise movement thereof. The reaction forces generated in the ratchet mechanism from the two combustion chambers thus tend to cancel each other out. The central ratchet mechanism includes a housing which absorbs the reaction forces from both combustion chambers and which is free to rotate in the event that the reaction forces generated in the two combustion chambers become unbalanced.
(FR)
Dans le moteur à combustion interne de type rotatif décrit, deux chambres de combustion espacées axialement (24a, 26a) sont prévues et un mécanisme d'encliquetage ou de commande commun (16) est placé entre les chambres de combustion espacées. Deux ailettes (40, 42, 44, 46) sont montées dans chaque chambre de combustion sur des arbres concentriques (36, 38), et peuvent tourner librement l'une par rapport à l'autre. Le mécanisme d'encliquetage placé entre les chambres de combustion fonctionne de façon à s'opposer au mouvement des ailettes dans le sens contraire à celui des aiguilles d'une montre dans l'une des chambres de combustion, tout en permettant leur mouvement dans l'autre sens. Les forces de réaction générées dans le mécanisme d'encliquetage à partir des deux chambres de combustion tendent par conséquent à s'éliminer les unes les autres. Le mécanisme d'encliquetage central comprend un logement qui absorbe les forces de réaction provenant des deux chambres de combustion et qui peut tourner librement dans le cas où les forces de réaction générées dans les deux chambres de combustion ne sont pas équilibrées.
